Abstract
Genetic analysis of 23 vegetable type Pigeon pea genotypes was studied to find out the variation and to measure the direct and indirect contribution on green pod yield per plant. The analysis of variance revealed significant differences among all the genotypes for the traits studied. The analyzed data indicated that the treatment mean sum of squares found to be highly significant for all the traits studied indicating the presence of large genetic variation amongst the genotypes selected for study. Genotypic and phenotypic coefficient of variation were of high magnitude for plant height,100 green pod weight,100 green seed weight, shelling percentage (%), TSS (%), days to 50% flowering, pod length, pod width and for number of primary branches per plant. The estimate of high heritability (bs) accompanied with high expected genetic advance for 100 green pod weight and days to 50% flowering indicate the presence of additive gene action in the expression of these characters. The direct effects of path coefficient analysis revealed that the green pod yield per plant had positive and significant effect with days to 50% flowering (0.0588), pod width (0.9276), pod length (0.4526), number of seeds per pod (0.0062), 100 green pod weight (0.0652) and 100 green seed weight (0.2128), shelling percentage (0.3972) and number of flower cluster (0.3709). Hence, the traits viz., 100 green pod weight, days to 50% flowering, number of seeds per pod and 100 green seed weight should be given more consideration while deciding selection criteria for vegetable type genotypes in pigeon pea.
