Abstract

Variability parameters were estimated for seed yield and seven other quantitative traits in 30 genotypes of green gram. Heritability estimates were high for all characters except for number of clusters and number of pods. High heritability coupled with high genetic advance were observed for plant height and seed yield. Path analysis revealed that all direct effects towards seed yield were positive and the maximum was observed in the case of pod yield and number of pods indicating they are important traits for selection.

Keywords: Variability, heritability, association analysis, path analysis
