Genetic Variability and Association Studies in Mid-late and Late Group of Cauliflower (Brassica oleracea L. var. botrytis)

Abstract

Sufficient genetic variability was recorded in 26 genotypes based on various genetic variability parameters, indicating the scope for selection. High heritability and genetic advance for days to curd initiation, curd solidity, gross plant weight, net curd weight and marketable curd weight indicate the importance of additive gene action. Correlation and path analysis directed to focus selection on the basis of gross plant weight, harvest index, curd size index, curd solidity, curd depth and net curd weight to evolve high-yielding cauliflower genotypes. DPCaf US, DPCa CMS 1, DPCaf W3, DPCaf 30, DPCaf W3 and DPCaf US showed promise for curd yield, mainly attributed to the traits identified based on parameters of genetic variability.
