Abstract :

In the present investigation, the genotypic and phenotypic coefficient of variations, heritability, genetic advance, correlation and path coefficient analysis were made for yield and its contributing characters in M4 populations of mungbean genotypes. High heritability (oad) along with high genetic advance as per cent of mean was observed for the trait plant height, number of pods per plant, number of seeds per pod, 100 seed weight and single plant yield indicating that these characters would be amenable for phenotypic selection. From the correlation studies the number of pods per plant were high positive and highly significant with single plant yield. Based on path coefficient analysis, the number of pods per plant followed by number of seeds per pod were the important characters for increasing yield in mungbean
