Genetic variability and path coefficient analysis in green gram (Vigna radiata)

REP.MB-2892

Genetic variability and path coefficient study of exotic collections of green gram population was conducted at the Agronomy Section, Agricultural Research Institute, Tandojam, Pakistan. Estimates of variability, heritability and expected genetic advance were computed for plant height, branches per plant, pods per plant, pod length, seeds per pod, 100 grain weight and grain yield per plant. High heritability values recorded for all the traits accompanied with high genetic advance suggest that all these characters are controlled by an additive gene effect and suitable selection schemes will result in significant genetic improvement. Further, the results of phenotypic correlation coefficient and path coefficient analysis indicate that maximum weightage should be given to branches, pods per plant, pod length and 100 grain weight in formulating selection indices for grain yield improvement in mungbean.
