Abstract
The present experiment entitled “Studies on heterosis and combining ability in Indian cauliflower (Brassica oleracea var. botrytis L.)” was carried out during 2017-18 and 2018-19 at horticultural research cum instructional farm, IGKV, Raipur (C.G.). The experiment was laid out in eight genotypes of cauliflower with three replications in randomized block design. The objectives to study “genetic variability, heritability, genetic advance, Path” and correlation association for various quantitative characters in cauliflower genotypes.
The analysis of variance in the present investigation indicated that “the mean sum of square due to genotypes were highly significant for most of the characters”. Curd yield expressed a “highly significant positive correlation with marketable curd weight”, curd size index, curd diameter no. of leaves per plant, and plant height at genotypic and phenotypic level, respectively.
ANOVA for line x tester revealed significant variance for most of the parameters in parent and hybrid. Higher and significant sca effects of crosses for curd yield identified the crosses Kartika x Sabour Agrim, IGC-8 x Pusa Meghna, IGC-9 x Pusa Ashwin, IGC-8 x Sabour Agrim, IGC-1 x Pusa Meghna.
Looking to the study of genotypes heterosis and combining ability for curd yield and its components characters in cauliflower was a framework for improvement and for getting promising high yielding genotypes of cauliflower with desirable traits under Chhattisgarh regions.
