Thirteen genotypes of early cauliflower were characterized for different quantitative parameters at the Vegetable Research Farm, at Bihar Agricultural University, Sabour during the Rabi season of 2010-2011 and 2011-2012. The experiment was laid out in a randomized complete block design with three replications. Pooled analysis of variance of the fifteen genotypes over two years indicated significant differences among the genotypes for all the characters under study. The range of variation was highest for marketable weight of curd followed by net weight of curd, days to 50% curd initiation, plant height, length of leaves and curd compactness. The traits such as net curd weight, curd compactness and marketable curd showed high PCV and GCV. High heritability along with moderate genetic advance were observed for marketable weight of curd, curd compactness, plant height and length of leaves which pointed towards the occurrence of additive gene action and hence phenotypic selection as such might be effective for improvement of these traits. Net weight of curd showed significant and positive genotypic and phenotypic correlation with plant height, length of leaves, width of leaves, diameter of curd, marketable weight of curd and curd compactness. Marketable weight of curd showed maximum direct positive contribution on net curd weight of curd at both genotypic and phenotypic level. The value for residual effect was found to be extremely low.
