Generation mean analysis for pod yield and its associated traits in garden pea (Pisum sativum L.)

Abstract

The present study was conducted to evaluate genetic and epistasis effects governing the inheritance of pod yield and yield components. Parental material comprising of six genetically different pea genotypes were crossed to produce F1, F2 and backcross generations. Means of the six generations were recorded for seven characters viz. plant height (cm), node bearing first flower, days to 50% flowering, pod length (cm), pod girth (cm), number of seed per pod and, total yield per plant (g). In present study three crosses (VRP-6 × GP-55, Pusa Pragati × GP-17 and Arkel × GP-48) showed significant dominance component [h] for pod yield. Significant estimates of additive component (d) along with significance of additive × additive (i) gene interaction with positive sign pod yield per plant which indicated the presence of increase alleles and associated pair of genes. It can be conclude that relative role of gene action was in general more complex for yield and other associated traits.
