Genetic components analysis for seed yield and its contributed traits in Indian mustard (Brassica juncea L. Czern & Coss)

Abstract

Analysis of variance revealed that the genotypes were genetically-differ to each for all the characters. Genetic components analysis exhibited that both additive and dominance components were highly significant for almost all the traits indicating the role of both additive as well as non-additive gene action in controlling the expression of concerned traits. In general dominance component values were higher than that of additive component for all the traits. The estimates of average degree of dominance indicated presence of over-dominance for all the traits.
