Abstract: The present investigation was undertaken at research cum instructional farm Indira Gandhi Krishi Vishwavidyalaya Raipur during kharif season of the year 2016-17 with 23 diverse genotypes of Indian cauliflower. The experiment was conducted in randomized block design with three replications. Genetic variability was studied for fifteen horticultural characters,three reproductive characters and three quality characters. Data were analysed statistically for genotypic and phenotypic coefficient of variation, heritability, genetic advance, correlation coefficients, path coefficient and level of self-incompatibility. The analysis of variance significantly differentiated for all the characters. According to mean performance of Indian cauliflower in respect to curd yield ton per hectare, IGC-1 (28.50) was found significantly superior than the other genotype evaluated. The high genotypic and phenotypic coefficient of variance was recorded for gross plant weight and net curd weight. High heritability coupled with high genetic advance was observed for net curd weight, marketable curd weight and gross curd weight. In correlation coefficient analysis charaters viz. plant height, leaf length, gross curd weight, marketable curd weight, net curd weight and curd size index exhibited the significant positive correlation with curd yield (t/ha) at both genotypic and phenotypic level whereas, days to 50 % curd initiation and days to 50 % curd maturity exhibited significant negative correlation with stalk length and curd yield at genotypic and phenotypic levels. In path coefficient analysis marketable curd weight showed maximum positive direct effect on curd yield followed by harvest index, gross curd weight, net curd weight, days to 50 % curd maturity, plant height, number of leaves per plant , curd width , leaf length, days to 50 % curd initiation , stalk length, leaf width. High level of self-incompatibility was observed in genotype Rajasthan late kunwari, IGC-4, IGC-8, IGC-7, Pusa Ashwin, Sabour Agrim, Rajasthan Early Kunwari and Pusa sharad, whereas 100% self-incompatibility was reported in Pusa Deepali.
