Abstract: The present investigation entitled “Studies on genetic divergence in garlic germplasm. in garlic (Allium sativum L.)”. The experiment was executed at Main Experiment, Station of Department of Vegetable Science, NDUAT Kumarganj Faizabad UP during Rabi season 2015-2016, with following objectives (1) to work out direct and indirect effects of different traits on yield and (2) to work out genetic divergence in garlic germplasm. The experimental material for the present study consisted of eighty genotypes, with plot size of 2.0 × 0.60 m² with distance of 30 cm row to row and 10 cm plant to plant. Observation were recorded on plant height (cm), number of leaves per plant, length of leaf (cm), width of leaf (cm), neck thickness of bulb (cm), diameter of bulb (cm), bulb yield per plant (g), number of cloves per bulb, length of clove (cm), weight of clove (g), diameter of clove (cm) and total soluble solids (%). The maximum positive direct effect on bulb yield per plant was exerted by number of cloves per bulb, weight of clove, total soluble solids, neck thickness of bulb, width of leaf and number of leaves per plant. It is suggested that selection for these traits will directly increase bulb yield per plant. The maximum inter-cluster distance was observed between cluster I and cluster IV which suggested that members of these two clusters are genetically very diverse to each other. The level of variation found in the genotypes showed great potentiality for improvement of garlic
