Mean performance studies in mid late and late group of cauliflower (Brassica oleracea L. var. botrytis)

The experimental material comprising of 26 genotypes belonging to mid late and late group was evaluated in randomized complete block design with three replications for two consecutive years during winter season of 2018-19 and 2019-20. Data were recorded on marketable curd yield per hectare and its 17 related traits. Sufficient genetic variability was observed for yield and component traits. The perusal of mean values of different genotypes showed wide variation in the performance with respect to marketable curd yield and its contributing traits. This indicates great extent of genetic diversity among genotypes which would provide immense opportunities for genetic improvement of cauliflower. The evaluation of mean performance revealed that DPCa CMS 1 showed advantage of 27% for marketable curd yield over standard check Palam Uphar followed by DPCaf W3, DPCaf US and DPCaf 30 which was mainly due to significant contribution of curd depth, curd diameter, leaf length, leaf width, optimum plant frame, curd compactness/solidity, gross and net plant weight.
