Studies on Genetic Variability, Correlation and Path Analysis for Yield and Yield Related Traits in Greengram [Vigna radiata (L.) Wilczek]

Abstract

components their direct and indirect effects on seed yield generating from the cross BL-865 × Chinamung in F\r2\rand F\r3\rgeneration to make effective selections. Highest GCV and PCV were observed for all the traits studied. On the basis of\rgenetic variability study all the growth and yield traits exhibited high heritability estimates (broad sense) coupled with high\rgenetic advance, indicating the preponderance of additive gene action. Hence, direct selection may be exercised for\rimprovement of these traits. Phenotypic coefficient of variation was slightly higher in magnitude than the genotypic\rcoefficient of variation. Number of pods per plant, pod yield per plant and threshing percentage had shown positive and\rsignificant correlation along with their high positive direct effect with seed yield, suggesting that these parameters may be\rconsidered as prime traits during the course of selection to have the higher potential of yield in green gram.
