The experiment was conducted in Augmented Block Design at Main Experimental Station of Department of Vegetable Science, Narendra Deva University of Agriculture, Narendra Nagar (Kumarganj), Faizabad (U.P.) during Rabi 2014-15 with the following objectives (1) To find out phenotypic and genotypic coefficient of variation (PCV & GCV), (2) to estimate heritability and genetic advance, Experimental material for the present study consisted of thirty genotypes. In single plot sized 2.0 X 0.30 cm with the distance of 30 cm row to row and 10 cm plant to plant. Observation were recorded on plant height (cm), leaves per plant, length of leaf (cm), width of leaf (cm), neck thickness of bulb (cm), cloves per bulb, weight of clove (g), length of clove (cm), length of bulb (cm), width of clove (cm), diameter of bulb (cm), total soluble solids (%) and bulb yield per plant (g).Analysis of variance for design of experiment indicated highly significant differences among treatments for all the characters, based on mean performance of genotypes, the NDG-43, NDG-49, Punjab Garlic, NDG-48 and NDG-45, were identified as most promising genotypes for bulb yield per plant. The higher magnitude of coefficient of variation at genotypic as well as phenotypic levels observed for leaves per plant, length of leaf, length of clove. High heritability coupled with high genetic advance in per cent of mean was recorded for number of cloves per bulb, Bulb yield per plant, weight of clove and width of leaf. It is suggested that selection for these traits will directly increase bulb yield per plant.
