Evaluation of biparental progenies for horticultural and quality traits in late cauliflower (Brassica oleracea var. botrytis L.)

Abstract

Sixteen biparental progenies developed from a cross PSB-1 x KT-9 in late cauliflower (Brassica oleracea var. botrytis L.) were evaluated in RBD with three replications for horticultural and quality traits. BIPs 13, 17 and 19 possessed good yield and quality traits. PCV was low for all the traits except gross plant weight and net curd weight. High heritability and low genetic gain recorded for days to marketable maturity indicated the nonadditive gene effects for this trait. Rest of the traits had low to moderate heritability with low genetic gain indicated the influence of environment. Net curd weight had highly significant and positive association with leaf length, leaf breadth, gross plant weight and harvest index. Path analysis revealed that contributions of gross plant weight and harvest index were maximum directly/indirectly.
