Genetic Variability, Correlation and Path Analysis in Mungbean [Vigna radiata (L.) Wilczek]

Abstract

Thirty mungbean genotypes were evaluated for the estimation of genetic variability, heritability, genetic advance, correlation coefficient, and path coefficient analysis for yield and its component traits. A considerable amount of genetic variability was observed among all the genotypes for all the characters under study. GCV & PCV were highest for seed yield per plant, followed by harvest index, biological yield and number of pods per plant. High genetic advance coupled with high heritability were observed for plant height, number of branches per plant, pod length, seed per pod, 100-seed weight, number of pods per plant, biological yield, seed yield and harvest index. Combined results of correlation coefficient and path analysis revealed that pods per branch, pod length, biological yield and harvest index are major component traits for the improvement of grain yield.
