Association studies for yield and some yield contributing morpho-physiological components in cauliflower (Brassica oleracea L. var. botrytis L.)

Abstract

Twenty five genotypes of cauliflower along with one check Madhuri were evaluated for yield and some yield contributing morpho physiological components in cauliflower. Further, the investigation was done to find out interrelationships among different characters and their direct and indirect contribution towards yield. Estimates of phenotypic and genotypic correlation coefficient revealed that marketable yield per plant was significantly and positively correlated with curd size index, gross weight per plant, curd solidity, curd compactness, curd diameter, stalk length, number of leaves per plant and harvest index. The high positive direct effect on marketable yield per plant was exhibited by curd size index, gross weight per plant, days to marketable curd maturity from date of transplanting, curd solidity, stalk length and per cent marketable curds. Therefore, these traits should be considered as the selection criterion to improve the marketable yield per plant.
