Genetic variability and correlations studies on yield and its components in mungbean (Vigna radiata (L.) Wilezek)

Abstract

Twenty diverse mungbean (Vigna radiata L. Wilkeezek) genotypes were evaluated for the estimation of genetic variability, heritability, genetic advance, correlation coefficient and path coefficient analysis for ten quantitative characters. The genotypes differed significantly for all characters studied. Higher genotypic and phenotypic coefficient of variation was observed for seed yield and number of pods per plant. Maximum heritability values were recorded in seed protein content, plant height and test weight. High heritability coupled with high genetic advance was observed in pods per plant, plant height and test weight indicating the importance of additive gene effect for expression of these characters. Character association indicated that pods per plant and plant height have significant positive correlation with seed yield. Maximum direct effect on seed yield was observed through pods per plant, test weight and plant height. © 2007 Asian Network for Scientific Information.
