Twenty five genotypes of cauliflower along with one check Madhuri were evaluated for yield and some yield contributing morpho-physiological components in cauliflower. The analysis of variance revealed that mean squares due to genotypes were significant for all the traits highlighting the presence of sufficient genetic variability among the genotypes. The hybrids H 1 and H 4 were found superior for traits like days to initiation of curd from transplanting, days to marketable curd maturity from date of transplanting, curd compactness, curd solidity and harvest index and comparable in performance for marketable yield per plant, gross weight per plant and curd diameter with standard check Madhuri. | Studies on mean performance for yield and its contributing traits in cauliflower Brassica oleracea L. var. botrytis L. under mid hill conditions of north-western Himalayas
