Abstract:
Genetic variability, correlation and path coefficient analysis was studied in cauliflower (Brassica oleracea var. botrytis) genotypes. The analysis of variance revealed significant differences among the genotypes for all the characters studied indicating a high degree of variability in the material. High PCV and GCV were recorded for yield per plot, yield per hectare, net curd weight, gross curd weight, curd size, curd compactness and number of leaves per plant indicating variation among these traits. High heritability and genetic advance as percent of mean were recorded for curd diameter, plant height, plant spread, number of leaves per hectare, curd size, curd compactness, net curd weight, gross curd weight, yield per plot and yield per hectare. Therefore, selection for these traits may accumulate more additive genes and leads to further development in their performance in cauliflower breeding programme. The yield per hectare showed significant positive correlation with plant height, plant spread, curd diameter, curd size, gross curd weight, net curd weight, curd compactness and yield per plot. Hence, selection for these traits helps in the yield improvement. Path analysis showed that yield per plot, net curd weight, number of leaves per plant, curd diameter, plant spread and curd compactness exerted positive direct effect on yield per hectare and also showed positive significant correlation with yield per hectare indicating true relationship between the traits.
