Genetic variability and correlation analysis for yield and yield attributing traits in mungbean [Vigna radiata (L). Wilczek]

Abstract

Twenty mungbean (Vigna radiata (L.) Wilczek) genotypes were evaluated for the estimation of genetic variability parameters, correlation coefficient, path analysis, heritability and genetic advance. The genotypes differed significantly for all the characters. Higher GCV and PCV was observed for the seed index. High heritability coupled with genetic advance as percent of mean showed by harvest index indicating the impact of additive gene expression. The characters days to number of seeds per pod and harvest index showed positive and significant correlation along with positive direct effect on grain yield. Therefore, selection based on this component traits would results improvement in grain yield of mungbean.
