The dependence of such a large population to meet their daily dietary requirements on this tropical crop causes different insect-pests of rice that significantly reduce crop yield, and quality as well as affect marketability in different parts of the world. Traditionally, several pesticides have been utilized to prevent the insect-pest, but this approach has various drawbacks, including the development of pesticide resistance, and negative effects on the environment and human health. Therefore, it was essential to screen the bacterial leaf blight (BLB), blast, brown spot, narrow brown leaf spot (NBLS), sheath rot, yellow stem borer (YSB) and leaf folder resistant rice genotypes under sodic soil conditions at Main Experimental Station of ANDUAT, Ayodhya, (U.P.), during 2016 to 2018. The present investigation reveals that the genotype Sushk Samrat showed high resistance for brown spot, NBLS, sheath rot, YSB, and leaf folder as well as resistance for Blast followed by CSR 10 showed high resistance for BLB, sheath rot, YSB and resistance for brown spot & Sarjoo 52 showed highly resistant for brown spot, sheath rot, leaf folder and resistant BLB, NBLS, YSB, respectively. The majority of cross combinations of the highly resistant parents showed high resistance and resistance in F 1 s, the best heterotic combination is Narendra Usar Dhan 2 x Narendra Usar Dhan 3 showed highly resistant for blast, brown spot, sheath rot, YSB, and resistance for BLB, NBLS, leaf folder; IR-85897x Narendra Usar Dhan 3 showed highly resistant for NBLS, sheath rot, YSB, and resistant for BLB, blast, leaf folder; Sushk Samrat x Narendra Usar Dhan 3 showed highly resistant for brown spot, YSB, and resistant for BLB, blast, NBLS, sheath rot, leaf folder; Sarjoo 52 x Narendra Usar Dhan 3 showed highly resistant for sheath rot, YSM, and resistant for BLB, blast, brown spot, NBLS and leaf folder. It reflects that Sushk Samrat and Sarjoo 52 have strong genetic backgrounds responsible for resisting these elite genetic stocks against various diseases prevalent in this northeast plainagro-climatic zone. Hence, these varieties can be utilized as donors in hybridization programmes to pyramid various biotic and abiotic stresses in widely adopted cultivars to increase productivity in sodic soil areas. Rice bacterial leaf blight blast brown spot narrow brown leaf spot sheath rot yellow stem borer and leaf folder Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Figure 8 Introduction Rice ( Oryza sativa L.), belongs to the family Gramineae (Poaceae), chromosome number 2n = 24 (n = 12) and basic chromosome number x = 5, which is due to a meiotic irregularity in chromosome number 2. The genome (AA) of rice comprises a total length of 430 Mb (megabase, a nucleotide length of 1000 000 base pairs) corresponding to about 1500 cM (centiMorgan, a genetic unit of length measured by the crossing-over frequency in genetic recombinations at meiosis) (Kurata et al., 1994 b; Harushima et al., 1998 ). Thus, in rice, each cM corresponds to a mean of 290 kb and 15 meiotic recombinations. This statistic varies amongst species and with genome size; rice has a relatively small genome (430 Mb) compared with that of other common cereals [maize, 3000 Mb; barley, 3500 Mb; wheat (a hexaploid species with A, B and D genomes), 7000 Mb]. However, in contrast to genome size, the genetic distance of these plants is very similar and lies between 1200 and 1500 cM. Thus, recombination occurs at much the same frequency in meiosis in each cereal, even though the genome sizes differ by more than eight‐fold. The genus Oryza comprises 24 species, only two of which are widely cultivated, O. sativa (Asian rice) and O. glaberrima (African rice). Oryza sativa is widely cultivated from tropical to temperate zones, whereas O. glaberrima is traditionally grown in West Africa, although O. sativa cultivation is becoming steadily more dominant in Africa due to superior grain quality features, ease of grain processing, and higher yield. The three subspecies or races of cultivated Asian rice ( O. sativa) are Indica (India), Japonica (Japan), and Javanica (Indonesia). Rice is one of the oldest cereal grains in the world, and people have grown it ii 5,000 BC. It is the major source of calories for more than half of the global population, and 90% of the world’s rice comes from Asia. Rice provides more than 15 essential vitamins and minerals including, folic acid, B vitamins, potassium, magnesium, selenium, fibre, iron, and zinc. It is gluten-free, highly digestible, and the least allergenic of all grains, making it an important grain option for those with celiac disease, gluten intolerance, or other food sensitivities. Asia is the leader in rice production accounting for about 90% of the world’s production. In Asia, China is the largest producer of rice with 149 million metric tons in 2021-22 followed by India (129.47 million metric tons) and Bangladesh (35.85 million metric tons). In India, Uttar Pradesh is the largest rice producer state with 16.76 million metric tons in 2021-22 followed by West Bengal (15.27 million metric tons) and Punjab (12.88 million metric tons). About 75% of the world’s supply is consumed by people in Asian countries and thus, rice is of immense importance to food security of Asia. The demand for rice is expected to increase with a continuous increase in global population. Rice, being the staple food for more than 70 per cent of our national population and a source of livelihood for 120–125 million rural households, is the backbone of Indian Agriculture. Although, the average productivity of rice is much lower in India than the average productivity at the world level. Therefore, the development of high-yielding, widely adapted pure line rice varieties coupled with advances in production technology in past four decades has enabled us to cope with the demand of rice to a satisfactory level. Thus, development of improved high yielding pure line and hybrid rice varieties suitable for adverse conditions (salt affected soil) and having multiple resistance would be an important strategy to meet this challenge. In India, rice productivity is very low as compared to other developed nations due to several biotic and abiotic factors. Generally, rice crop is affected by more than 20 diseases and certain diseases are more common in rice varieties. Among the different diseases, bacterial leaf blight, blast, brown spot, narrow brown spot, sheath blight, and stem rot are considered important in various parts of rice growing areas of the world. Bacterial leaf blight (BLB), caused by Xanthomonas oryzae. pv. oryzae , which belongs to Domain- Bacteria , Phylum- Pseudomonadata , Class- Gammaproteobacteria , Order- Xanthomonadales , Family- Xanthomonadaceae , Genus- Xanthomonas and Species- oryzae. The Xanthomonas bacteria are single-celled, rod-shaped gram-negative bacteria with dimensions of 1.2 x 0.3–0.5 µm. They lack capsules and do not generate spores. On nutrient agar, their colonies are round, smooth, and pale yellow with an entire border. The gene Xa21 is sufficient to confers resistance to multiple X. oryzae pv. oryzae isolates in rice plants. There are three phases of BLB disease viz. , Leaf blight, Kresek (the seedling blight or wilt phase) and Pale-yellow leaf. It occurs mostly during the rainy season and in some Asian regions, reducing crop production by up to 50%. (Latif et al., 2011 ). Rice blast ( Pyricularia oryzae ) is one of the most severe diseases, particularly where rice crop is irrigated or receives high amounts of rainfall (RH 90% or higher) and affects the leaves, causes diamond-shaped white to grey or reddish-brown lesions with reddish to brown borders; the lesions may enlarge, coalesce, and kill entire leaves. It also attacks on the panicle neck node and is called the neck rot, neck blast, or panicle blast stage of the disease. If infection of the panicle neck occurs early, the grains do not fill and the panicle remains erect. If the panicle neck is infected late, the grains become partially filled, and because of the weight of the grains, the base of the panicle breaks and the panicle droops. Rice seedlings and young leaf and stem tissues are more susceptible than older plants and tissues. Rice blast is favoured greatly by high nitrogen fertilization, prolonged leaf wetness, and night temperatures around 20°C. The teleomorph stage ( Magnaporthe grisea ), has not been found in nature, but it has been produced after crossing appropriate compatible isolates in the laboratory. It has seven chromosomes and a genome size of 40Mb, with approximately 9,000 genes. The pathogen is a haploid ascomycete that produces conidia on aerial conidiophores emerging from the center of lesions. The conidia consist of three cells. Each conidium contains an adhesive glycoprotein. When rice leaf or stem surfaces are wet, the conidia germinate and the germ tube produces an appressorium through which the fungus penetrates plant surfaces or enters through stomata. New disease lesions become apparent about 4 days after inoculation. The fungus also produces several toxins, e.g., pyricularin and a-picolinic acid that seem to contribute to the development of rice blast. The production and accumulation of melanins in the appressorium cell wall seem to be necessary for successful penetration. The presence of glycerol increases the turgor pressure of the appressorium allowing the penetration peg to puncture the plant epidermal cells and the cell wall and enter the cell. Appressorial walls of Magnaporthe grisea contain melanin that prevents glycerol from leaking out, while Melanin-deficient mutants are unable to generate turgor pressure and are, therefore, non-pathogenic. In M. grisea , several genes have been shown to control appressorial development. One such gene, hydrophobin (MPG1), is essential for appressorial formation and, when disrupted, the fungus not only has reduced pathogenicity, it produces 100 times fewer conidia. Transcription of the mpg1 gene is controlled by three regulatory genes, two of which are also involved in the regulation of nitrogen metabolism. Another gene expressed in spores of M. grisea resembles transcription factors, but its disruption leads to the production of defective conidia and impaired appressorium formation, both of which cause loss of pathogenicity. A still different gene, pth11, encodes a protein that is embedded in the cell membrane and apparently enables the fungus to recognize the host surface and to form normal appressoria; disruption of that gene makes the fungus unable to infect the host. Mutants missing Pth11 do not form appressoria and cannot infect plants. The rice blast fungus ( Magnaporthe grisea ) also carries the avirulence gene avr-Pi-ta effective on rice cultivars carrying the resistance gene Pi-ta. Pi-ta encodes a cytoplasmic protein that contains an NBS domain and a leucine-rich carboxyl terminus. Brown spot of rice caused by Helminthosporium oryzae (Sexual stage: Cochliobolus miyabeanus ), which belongs to Domain- Eukarya , Kingdom- Fungi , Phylum- Ascomycota , Class- Dothideomycetes , Order- Pleosporales , Family- Pleosporaceae , Genus- Cochliobolus , and Species- miyabeanus. It reduces crop production by up to 40%. However, rice genotypes may vary in their response to disease tolerance. The fungus is reported to survive in soil and infected plant parts including stubbles, straw and grains for 2–3 years, which act as a primary source of inoculums. The primary infection is usually initiated by the infected seed as necrotic lesions on the coleoptile and sheath of first leaves appear. The subsequent lesion on leaves mostly arise from secondary infection by air-borne spores produced on primary lesions. The spores of H. oryzae were found present throughout the year in the air but their quantities were greater during the cooler months with higher humidity. Sheath blight is an important soil-borne disease caused by Rhizoctonia solani (Sexual stage: Thanetophorus cucumeris ), which belongs to Domain- Eukarya , Kingdom- Fungi , Phylum- Basidiomycota , Class- Agaricomycetes , Order- Cantharellales , Family- Ceratobasidiaceae , Genus- Rhizoctonia and Species- solani. The crop is affected by the fungus from the tillering to the heading stages. On leaf sheaths close to the water's surface, the first signs are observed. Oval, elliptical, or irregular greenish-gray dots develop on the leaf sheath. When a leaf sheath has numerous big lesions, the entire leaf usually dies, and in extreme circumstances, the entire plant's leaves may be blighted.The infection extends to the inner sheaths resulting in death of the entire plant. It causes up to 25% yield loss (Kumar et al., 2009 ). Sheath rot of rice is caused by Sarocladium oryzae , which belongs to Kingdom: Fungi, Phylum: Ascomycota, Order: Hypocreales, Family: Sarocladiaceae, Genus: Sarocladium and Species: oryzae. It was originally described as Acrocylindrium oryzae , the first organism to be associated with rice sheath rot symptoms isolated in Taiwan in 1922 (Mew and Gonzales, 2002). The genus Sarocladium was established in 1975 (Gams and Hawksworth, 1975) and currently encompasses 16 species including plant pathogens, saprobes, mycoparasites, endophytes, and potential human pathogens (Giraldo et al., 2015 ). The fungus produces white mycelium which is sparsely branched and septate. Conidiophores that form from the mycelium are branched once or twice, with 3–4 branches in each whorl, and are significantly thicker than vegetative hyphae. The ultimate branches are phialides and produce conidia that are smooth, single-celled, hyaline, cylindrical to slightly fusiform, usually moderately curved, and 4–9 x 1-2.5 m in size. The fungus enters the rice plant by its stomata and wounds and spreads intercellularly in the mesophyll and vascular bundle tissues. Mycelium from the sheath rot fungus can be found on seeds and infected debris. The fungus usually causes the uppermost leaf sheaths that surround newborn panicles begins to rot, which delays or prevents the emergence of the panicles. The disease is significant when the rice crop is getting ready to mature. Sheath rot lesions are sometimes confused with sheath blight lesions. However, sheath rot occurs higher on the plant than sheath blight normally does and interferes with the panicle exsertion and reduces grain yield by retarding or aborting panicle emergence, and producing unfilled seeds and sterile panicles causing panicles to rot and grains to become discolored. Sheath blight occurs on leaves and lower portions of the plant and will not interfere with panicle exsertion. Rainfed lowland rice is the second most important rice ecosystem, representing about 25% of the total rice production area. Rainfed lowland ecosystem is always prone to drought stress and most traditional as well as high yielding varieties of the present time are susceptible to drought (Kumar et al. , 2012). Yet, the response of rice genotypes to disease tolerance may differ. Keeping in view the above facts, the present study was undertaken to identify the rice genotypes against five major rice diseases (bacterial leaf blight, blast, brown spot, narrow brown spot and sheath rot) and two insect-pests (rice stem borer and leaf folder) under sodic stress condition. Dramatic changes in climatic conditions that supplement the biotic and abiotic stresses pose severe threat to the sustainable rice production and have made it a difficult task for rice breeders to enhance production and productivity under these stress factors. The impact of soil sodicity on the growth and yield of crop plant is a most serious issue worldwide. Soil salinity is an also major abiotic stresses that adversely affect the growth and yields. Given the foregoing, the current study was designed to discover rice genotypes resistant to multiple important rice diseases under sodic soil conditions. Materials and Methods This experiment was conducted at the Main Experimental Station of Acharya Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Ayodhya (U. P.)

None of the genotype was found susceptible and highly susceptible for leaf folder. Discussion Screening of genotypes against diseases and insects The use of resistant varieties is the best option of disease control. Therefore, studies were planned to search out the resistant genotypes of rice under sodic soil. In India, not much emphasis has been given to search on resistant genotypes of rice. All together eighty nine genotypes (twenty one lines, three testers, sixty three F 1 s crosses, and two checks) were screened for their reaction to Bacterial leaf blight ( Xanthomonas oryzae pv. oryzae ), Blast ( Pyricularia oryzae) , Brown spot ( Dreschlera oryzae) , Narrow brown leaf spot (C ercospora janseana/ oryzae ), Sheath rot ( Sarocladium oryzae/attenuatum ), Yellow stem sorer ( Scirpophaga incertulas ) and Leaf folder (Cnaphalocrosis medinalis) in the field. Disease management is best accomplished by the adoption of resistant cultivars. As a result, experiments were planned to identify resistant genotypes of rice in sodic soil. The hunt for resistant rice genotypes has received little attention in India. All together eighty nine genotypes (twenty one lines, three testers, sixty three F 1 s and two checks) were screened for their reaction to Bacterial leaf blight ( Xanthomonas oryzae pv. oryzae ), Blast ( Pyricularia oryzae ), Brown spot ( Dreschlera oryzae ), Narrow brown leaf spot ( Cercospora janseana/ oryzae ), Sheath rot ( Sarocladium oryzae/attenuatum ), Yellow stem sorer ( Scirpophaga incertulas ) and Leaf folder ( Cnaphalocrosis medinalis ) in the field. 1.

India","fulltext":[{"header":"Introduction","content":"\u003cp\u003eRice (\u003cem\u003eOryza sativa\u003c/em\u003e L.), belongs to the family Gramineae (Poaceae), chromosome number 2n\u0026thinsp;=\u0026thinsp;24 (n\u0026thinsp;=\u0026thinsp;12) and basic chromosome number x\u0026thinsp;=\u0026thinsp;5, which is due to a meiotic irregularity in chromosome number 2. The genome (AA) of rice comprises a total length of 430 Mb (megabase, a nucleotide length of 1000 000 base pairs) corresponding to about 1500 cM (centiMorgan, a genetic unit of length measured by the crossing-over frequency in genetic recombinations at meiosis) (Kurata et al., \u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e1994\u003c/span\u003eb; Harushima et al., \u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e1998\u003c/span\u003e). Thus, in rice, each cM corresponds to a mean of 290 kb and 15 meiotic recombinations. This statistic varies amongst species and with genome size; rice has a relatively small genome (430 Mb) compared with that of other common cereals [maize, 3000 Mb; barley, 3500 Mb; wheat (a hexaploid species with A, B and D genomes), 7000 Mb]. However, in contrast to genome size, the genetic distance of these plants is very similar and lies between 1200 and 1500 cM. Thus, recombination occurs at much the same frequency in meiosis in each cereal, even though the genome sizes differ by more than eight‐fold. The genus \u003cem\u003eOryza\u003c/em\u003e comprises 24 species, only two of which are widely cultivated, \u003cem\u003eO. sativa\u003c/em\u003e (Asian rice) and \u003cem\u003eO. glaberrima\u003c/em\u003e (African rice). \u003cem\u003eOryza sativa\u003c/em\u003e is widely cultivated from tropical to temperate zones, whereas \u003cem\u003eO. glaberrima\u003c/em\u003e is traditionally grown in West Africa, although \u003cem\u003eO. sativa\u003c/em\u003e cultivation is becoming steadily more dominant in Africa due to superior grain quality features, ease of grain processing, and higher yield. The three subspecies or races of cultivated Asian rice (\u003cem\u003eO.\u003c/em\u003e sativa) are Indica (India), Japonica (Japan), and Javanica (Indonesia). Rice is one of the oldest cereal grains in the world, and people have grown it ii 5,000 BC. It is the major source of calories for more than half of the global population, and 90% of the world\u0026rsquo;s rice comes from Asia. Rice provides more than 15 essential vitamins and minerals including, folic acid, B vitamins, potassium, magnesium, selenium, fibre, iron, and zinc. It is gluten-free, highly digestible, and the least allergenic of all grains, making it an important grain option for those with celiac disease, gluten intolerance, or other food sensitivities. Asia is the leader in rice production accounting for about 90% of the world\u0026rsquo;s production. In Asia, China is the largest producer of rice with 149\u0026nbsp;million metric tons in 2021-22 followed by India (129.47\u0026nbsp;million metric tons) and Bangladesh (35.85\u0026nbsp;million metric tons). In India, Uttar Pradesh is the largest rice producer state with 16.76\u0026nbsp;million metric tons in 2021-22 followed by West Bengal (15.27\u0026nbsp;million metric tons) and Punjab (12.88\u0026nbsp;million metric tons). About 75% of the world\u0026rsquo;s supply is consumed by people in Asian countries and thus, rice is of immense importance to food security of Asia. The demand for rice is expected to increase with a continuous increase in global population. Rice, being the staple food for more than 70 per cent of our national population and a source of livelihood for 120\u0026ndash;125\u0026nbsp;million rural households, is the backbone of Indian Agriculture. Although, the average productivity of rice is much lower in India than the average productivity at the world level. Therefore, the development of high-yielding, widely adapted pure line rice varieties coupled with advances in production technology in past four decades has enabled us to cope with the demand of rice to a satisfactory level. Thus, development of improved high yielding pure line and hybrid rice varieties suitable for adverse conditions (salt affected soil) and having multiple resistance would be an important strategy to meet this challenge. In India, rice productivity is very low as compared to other developed nations due to several biotic and abiotic factors. Generally, rice crop is affected by more than 20 diseases and certain diseases are more common in rice varieties. Among the different diseases, bacterial leaf blight, blast, brown spot, narrow brown spot, sheath blight, and stem rot are considered important in various parts of rice growing areas of the world. Bacterial leaf blight (BLB), caused by \u003cem\u003eXanthomonas oryzae.\u003c/em\u003e pv. \u003cem\u003eoryzae\u003c/em\u003e, which belongs to Domain-\u003cem\u003eBacteria\u003c/em\u003e, Phylum- \u003cem\u003ePseudomonadata\u003c/em\u003e, Class- \u003cem\u003eGammaproteobacteria\u003c/em\u003e, Order- \u003cem\u003eXanthomonadales\u003c/em\u003e, Family- \u003cem\u003eXanthomonadaceae\u003c/em\u003e, Genus- \u003cem\u003eXanthomonas\u003c/em\u003e and Species- \u003cem\u003eoryzae.\u003c/em\u003e The \u003cem\u003eXanthomonas\u003c/em\u003e bacteria are single-celled, rod-shaped gram-negative bacteria with dimensions of 1.2 x 0.3\u0026ndash;0.5 \u0026micro;m. They lack capsules and do not generate spores. On nutrient agar, their colonies are round, smooth, and pale yellow with an entire border. The gene Xa21 is sufficient to confers resistance to multiple \u003cem\u003eX. oryzae\u003c/em\u003e pv.\u003cem\u003eoryzae\u003c/em\u003e isolates in rice plants. There are three phases of BLB disease \u003cem\u003eviz.\u003c/em\u003e, Leaf blight, Kresek (the seedling blight or wilt phase) and Pale-yellow leaf. It occurs mostly during the rainy season and in some Asian regions, reducing crop production by up to 50%. (Latif et al., \u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e2011\u003c/span\u003e). Rice blast (\u003cem\u003ePyricularia oryzae\u003c/em\u003e) is one of the most severe diseases, particularly where rice crop is irrigated or receives high amounts of rainfall (RH 90% or higher) and affects the leaves, causes diamond-shaped white to grey or reddish-brown lesions with reddish to brown borders; the lesions may enlarge, coalesce, and kill entire leaves. It also attacks on the panicle neck node and is called the neck rot, neck blast, or panicle blast stage of the disease. If infection of the panicle neck occurs early, the grains do not fill and the panicle remains erect. If the panicle neck is infected late, the grains become partially filled, and because of the weight of the grains, the base of the panicle breaks and the panicle droops. Rice seedlings and young leaf and stem tissues are more susceptible than older plants and tissues. Rice blast is favoured greatly by high nitrogen fertilization, prolonged leaf wetness, and night temperatures around 20\u0026deg;C. The teleomorph stage (\u003cem\u003eMagnaporthe grisea\u003c/em\u003e), has not been found in nature, but it has been produced after crossing appropriate compatible isolates in the laboratory. It has seven chromosomes and a genome size of 40Mb, with approximately 9,000 genes. The pathogen is a haploid ascomycete that produces conidia on aerial conidiophores emerging from the center of lesions. The conidia consist of three cells. Each conidium contains an adhesive glycoprotein. When rice leaf or stem surfaces are wet, the conidia germinate and the germ tube produces an appressorium through which the fungus penetrates plant surfaces or enters through stomata. New disease lesions become apparent about 4 days after inoculation. The fungus also produces several toxins, e.g., pyricularin and a-picolinic acid that seem to contribute to the development of rice blast. The production and accumulation of melanins in the appressorium cell wall seem to be necessary for successful penetration. The presence of glycerol increases the turgor pressure of the appressorium allowing the penetration peg to puncture the plant epidermal cells and the cell wall and enter the cell. Appressorial walls of \u003cem\u003eMagnaporthe grisea\u003c/em\u003e contain melanin that prevents glycerol from leaking out, while Melanin-deficient mutants are unable to generate turgor pressure and are, therefore, non-pathogenic. In \u003cem\u003eM. grisea\u003c/em\u003e, several genes have been shown to control appressorial development. One such gene, hydrophobin (MPG1), is essential for appressorial formation and, when disrupted, the fungus not only has reduced pathogenicity, it produces 100 times fewer conidia. Transcription of the mpg1 gene is controlled by three regulatory genes, two of which are also involved in the regulation of nitrogen metabolism. Another gene expressed in spores of \u003cem\u003eM. grisea\u003c/em\u003e resembles transcription factors, but its disruption leads to the production of defective conidia and impaired appressorium formation, both of which cause loss of pathogenicity. A still different gene, pth11, encodes a protein that is embedded in the cell membrane and apparently enables the fungus to recognize the host surface and to form normal appressoria; disruption of that gene makes the fungus unable to infect the host. Mutants missing \u003cem\u003ePth11\u003c/em\u003e do not form appressoria and cannot infect plants. The rice blast fungus (\u003cem\u003eMagnaporthe grisea\u003c/em\u003e) also carries the avirulence gene avr-Pi-ta effective on rice cultivars carrying the resistance gene Pi-ta. Pi-ta encodes a cytoplasmic protein that contains an NBS domain and a leucine-rich carboxyl terminus. Brown spot of rice caused by \u003cem\u003eHelminthosporium oryzae\u003c/em\u003e (Sexual stage: \u003cem\u003eCochliobolus miyabeanus\u003c/em\u003e), which belongs to Domain- \u003cem\u003eEukarya\u003c/em\u003e, Kingdom- \u003cem\u003eFungi\u003c/em\u003e, Phylum- \u003cem\u003eAscomycota\u003c/em\u003e, Class- \u003cem\u003eDothideomycetes\u003c/em\u003e, Order- \u003cem\u003ePleosporales\u003c/em\u003e, Family- \u003cem\u003ePleosporaceae\u003c/em\u003e, Genus- \u003cem\u003eCochliobolus\u003c/em\u003e, and Species- \u003cem\u003emiyabeanus.\u003c/em\u003e It reduces crop production by up to 40%. However, rice genotypes may vary in their response to disease tolerance. The fungus is reported to survive in soil and infected plant parts including stubbles, straw and grains for 2\u0026ndash;3 years, which act as a primary source of inoculums. The primary infection is usually initiated by the infected seed as necrotic lesions on the coleoptile and sheath of first leaves appear. The subsequent lesion on leaves mostly arise from secondary infection by air-borne spores produced on primary lesions. The spores of \u003cem\u003eH. oryzae\u003c/em\u003e were found present throughout the year in the air but their quantities were greater during the cooler months with higher humidity. Sheath blight is an important soil-borne disease caused by \u003cem\u003eRhizoctonia solani\u003c/em\u003e (Sexual stage: \u003cem\u003eThanetophorus cucumeris\u003c/em\u003e), which belongs to Domain- \u003cem\u003eEukarya\u003c/em\u003e, Kingdom- \u003cem\u003eFungi\u003c/em\u003e, Phylum- \u003cem\u003eBasidiomycota\u003c/em\u003e, Class- \u003cem\u003eAgaricomycetes\u003c/em\u003e, Order- \u003cem\u003eCantharellales\u003c/em\u003e, Family- \u003cem\u003eCeratobasidiaceae\u003c/em\u003e, Genus- \u003cem\u003eRhizoctonia\u003c/em\u003e and Species- \u003cem\u003esolani.\u003c/em\u003e The crop is affected by the fungus from the tillering to the heading stages. On leaf sheaths close to the water's surface, the first signs are observed. Oval, elliptical, or irregular greenish-gray dots develop on the leaf sheath. When a leaf sheath has numerous big lesions, the entire leaf usually dies, and in extreme circumstances, the entire plant's leaves may be blighted.The infection extends to the inner sheaths resulting in death of the entire plant. It causes up to 25% yield loss (Kumar et al., \u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e2009\u003c/span\u003e). Sheath rot of rice is caused by \u003cem\u003eSarocladium oryzae\u003c/em\u003e, which belongs to Kingdom: Fungi, Phylum: Ascomycota, Order: Hypocreales, Family: Sarocladiaceae, Genus: Sarocladium and Species: oryzae. It was originally described as \u003cem\u003eAcrocylindrium oryzae\u003c/em\u003e, the first organism to be associated with rice sheath rot symptoms isolated in Taiwan in 1922 (Mew and Gonzales, 2002). The genus Sarocladium was established in 1975 (Gams and Hawksworth, 1975) and currently encompasses 16 species including plant pathogens, saprobes, mycoparasites, endophytes, and potential human pathogens (Giraldo et al., \u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e2015\u003c/span\u003e). The fungus produces white mycelium which is sparsely branched and septate. Conidiophores that form from the mycelium are branched once or twice, with 3\u0026ndash;4 branches in each whorl, and are significantly thicker than vegetative hyphae. The ultimate branches are phialides and produce conidia that are smooth, single-celled, hyaline, cylindrical to slightly fusiform, usually moderately curved, and 4\u0026ndash;9 x 1-2.5 m in size. The fungus enters the rice plant by its stomata and wounds and spreads intercellularly in the mesophyll and vascular bundle tissues. Mycelium from the sheath rot fungus can be found on seeds and infected debris. The fungus usually causes the uppermost leaf sheaths that surround newborn panicles begins to rot, which delays or prevents the emergence of the panicles. The disease is significant when the rice crop is getting ready to mature. Sheath rot lesions are sometimes confused with sheath blight lesions. However, sheath rot occurs higher on the plant than sheath blight normally does and interferes with the panicle exsertion and reduces grain yield by retarding or aborting panicle emergence, and producing unfilled seeds and sterile panicles causing panicles to rot and grains to become discolored. Sheath blight occurs on leaves and lower portions of the plant and will not interfere with panicle exsertion. Rainfed lowland rice is the second most important rice ecosystem, representing about 25% of the total rice production area. Rainfed lowland ecosystem is always prone to drought stress and most traditional as well as high yielding varieties of the present time are susceptible to drought (Kumar \u003cem\u003eet al.\u003c/em\u003e, 2012). Yet, the response of rice genotypes to disease tolerance may differ. Keeping in view the above facts, the present study was undertaken to identify the rice genotypes against five major rice diseases (bacterial leaf blight, blast, brown spot, narrow brown spot and sheath rot) and two insect-pests (rice stem borer and leaf folder) under sodic stress condition. Dramatic changes in climatic conditions that supplement the biotic and abiotic stresses pose severe threat to the sustainable rice production and have made it a difficult task for rice breeders to enhance production and productivity under these stress factors. The impact of soil sodicity on the growth and yield of crop plant is a most serious issue worldwide. Soil salinity is an also major abiotic stresses that adversely affect the growth and yields. Given the foregoing, the current study was designed to discover rice genotypes resistant to multiple important rice diseases under sodic soil conditions.\u003c/p\u003e"},{"header":"Materials and Methods","content":"\u003cp\u003eThis experiment was conducted at the Main Experimental Station of Acharya Narendra Deva University of Agriculture \u0026amp; Technology, Narendra Nagar (Kumarganj), Ayodhya (U.

The dependence of such a large population to meet their daily dietary requirements on this tropical crop causes different insect-pests of rice that significantly reduce crop yield, and quality as well as affect marketability in different parts of the world. Traditionally, several pesticides have been utilized to prevent the insect-pest, but this approach has various drawbacks, including the development of pesticide resistance, and negative effects on the environment and human health. Therefore, it was essential to screen the bacterial leaf blight (BLB), blast, brown spot, narrow brown leaf spot (NBLS), sheath rot, yellow stem borer (YSB) and leaf folder resistant rice genotypes under sodic soil conditions at Main Experimental Station of ANDUAT, Ayodhya, (U.P.), during 2016 to 2018. The present investigation reveals that the genotype Sushk Samrat showed high resistance for brown spot, NBLS, sheath rot, YSB, and leaf folder as well as resistance for Blast followed by CSR 10 showed high resistance for BLB, sheath rot, YSB and resistance for brown spot \u0026amp; Sarjoo 52 showed highly resistant for brown spot, sheath rot, leaf folder and resistant BLB, NBLS, YSB, respectively. The majority of cross combinations of the highly resistant parents showed high resistance and resistance in F\u003csub\u003e1\u003c/sub\u003es, the best heterotic combination is Narendra Usar Dhan 2 x Narendra Usar Dhan 3 showed highly resistant for blast, brown spot, sheath rot, YSB, and resistance for BLB, NBLS, leaf folder; IR-85897x Narendra Usar Dhan 3 showed highly resistant for NBLS, sheath rot, YSB, and resistant for BLB, blast, leaf folder; Sushk Samrat x Narendra Usar Dhan 3 showed highly resistant for brown spot, YSB, and resistant for BLB, blast, NBLS, sheath rot, leaf folder; Sarjoo 52 x Narendra Usar Dhan 3 showed highly resistant for sheath rot, YSM, and resistant for BLB, blast, brown spot, NBLS and leaf folder. It reflects that Sushk Samrat and Sarjoo 52 have strong genetic backgrounds responsible for resisting these elite genetic stocks against various diseases prevalent in this northeast plainagro-climatic zone.
