Assessment of genetic variability and character association in mid-late/late cauliflower genotypes

Abstract

The present investigation comprising 36 diverse cauliflower genotypes along with three checks were raised during winter season of 2021-22 to study genetic variability, association between different characters, and direct and indirect effects of component traits to formulate selection criteria for utilization in crop improvement programme. The analysis of variance indicated exitance of sufficient genetic variability for all morphological and yield traits taken for the study. High PCV and GCV were reported for marketable curd weight, net curd weight and stalk length. Similarly, high heritability coupled with high genetic advance was observed for gross plant weight, marketable curd weight and curd solidity which indicates that these traits can be easily improved through simple selection. Correlation and path coefficient analysis revealed that gross plant weight, net curd weight, curd size index, curd solidity, plant frame and stalk length could be considered as the best selection parameters for evolving high yielding cauliflower genotypes.
