The present investigation was undertaken to evaluate 34 garlic genotypes for yield and its contributing traits in order to assess genetic variability, heritability and genetic advance during rabi 2019-20 at Vegetable Research Farm, C. S. Azad University of Agriculture and Technology, Kalyanpur, Kanpur (Uttar Pradesh). Analysis of variance table revealed that the mean sum of squares due to genotypes were highly significant for all the traits. In general, estimates of phenotypic coefficients of variation (PCV) for all traits were slightly higher than their corresponding genotypic coefficient of variation (GCV). Characters average weight of bulb and average weight of cloves per bulb showed the higher phenotypic and genotypic coefficient of variation among all the characters. Highest heritability was observed for equatorial diameter, clove length, leaf length, average weight of bulb, polar diameter, average weight of cloves per bulb, marketable bulb yield, number of cloves per bulb, width of cloves and number of leaves per plant. High heritability coupled with high genetic advance as percent of mean (GAM) was observed for average weight of bulb, average weight of cloves per bulb, number of cloves per bulb, marketable bulb yield and width of cloves indicating the presence of additive gene action for the expression of these traits.
