Character association analysis for yield and its component traits in groundnut (Arachis hypogaea L.)

Abstract

Twenty-one groundnut genotypes with two checks viz., LGN-1 and JL-24 were evaluated for character association analysis in randomized block design with 3 replications under rainfed condition at Oilseeds Research Station, Latur (E1), Oilseeds Research Sub-Station, Ambajogai (E2) and Agricultural Research Station, Badnapur (E3) kharif, 2018-19. The character association studies revealed that the improvement in pod yield in groundnut is achieved through improvement in yield components. The component characters like number of mature pods per plant, kernel yield per plant, 100 kernel weight and sound mature kernel exhibited positive and significant association with pod yield.
