Analysis of Seed Yield Components in Lablab purpureus L.

Abstract

An analysis of seed yield components was performed for eight characters in ten genotypes of lablab bean (Lablab purpureus L). Significant genotypic differences were observed for all the traits studied, viz., seed yield plant^-1, seeds pod^-1, seed weight, pod length, pod weight, seed weight pod^-1, dry matter yield plant^-1 and. seed germination. The variabilities recorded were highest in seed yield plant^-1 and dry matter yield plant^-1, and moderate for pod weight, seed weight pod^-1 and l00-seed weight. The heritability estimates were high for dry matter yield plant^-1 and seed yield plant^-1 , moderate for 100-seed weight, seed weight pod^-1 and pod weight, and low for rest of the traits. Path analysis revealed that seed weight pod^-1, 100-seed weight, pod length, pod weight and seeds pod^-1 had positive effect on seed yield, and indicated that these traits might help in identifying high yielding varieties of lablab bean.
