Variability, heritability and genetic advance analysis for yield and its contributing traits in cluster bean

Thirty diverse genotype of cluster bean were evaluated to study variability, heritability and Genetic Advance for yield and its contributing characters. Variation in genetic constituent leads to increasing phenotypic expression of the quantitative characters of individuals. The phenotypic coefficient of variation (PCV) was higher than the genotypic coefficient of variation (GCV) in all the characters indicating higher influence of environment. A considerable amount of variability (gcv) varied from 2.69 for days to 50% flowering to 67.57 for seed yield per plant and the estimates of pcv varied from 3.02 for days to 50% flowering to 70.65 for seed yield per plant. The genetic advance varied from 0.30 for 100-Seed weight to 27.45 for Plant height. High estimates of genetic advance were reported for plant height. However, high heritability estimates was associated with high predicted genetic advance for plant height These traits were mostly governed by additive gene action. And these characters are important for the breeder to construct selection indices.
