ABSTRACT
Thirty one dry bean genotypes were used to study their performance, genetic variability, heritability and genetic advance of yield and yield contributing characters viz., days to 50% flowering, days to maturity, plant height, number of pods plant ha-1 , pod length, number of seeds plant ha-1 , 20 seed weight. Significant variations were observed for all the characters in all the genotypes used in the experiment. Highest and genotypic and phenotypic variations were observed for days to maturity and pod length, respectively. All the characters showed high heritability with high genetic advance. Grain yield was found to be positively correlated with number of pods plant ha-1 , pod length, number of seeds plant ha-1 and 20 seed weight. Path coefficient analysis revealed that all the pod and seed characters showed positive and significant direct effects on seed yield.
