Correlation Analysis Among Yield and Its Component Traits in F2 Population of Groundnut (Arachis hypogaea L.) Derived from TCGS 1694 × ICGV 201179

Groundnut (Arachis hypogaea L.) is a vital oilseed crop cultivated extensively for its economic and nutritional value. Enhancing pod yield remains a key objective in groundnut breeding programs. In the present study, an F₂ population derived from the cross TCGS 1694 × ICGV 201179 was evaluated at the Regional Agricultural Research Station (RARS), Acharya N.G. Ranga Agricultural University (ANGRAU), Tirupati, Andhra Pradesh, during the kharif season of 2024. The objective was to assess the correlation among seven yield and yield-attributing traits to identify potential selection criteria for improving pod yield. The analysis revealed that pod yield per plant exhibited a highly significant positive correlation with seed yield per plant, followed by number of pods per plant, number of seeds per plant, hundred pod weight, hundred seed weight, and shelling out-turn percentage. These findings suggest that these traits are closely associated with pod yield and can be effectively utilized as indirect selection indices in the advancement of high-yielding groundnut genotypes.
