Abstract: The present investigation entitled “Genetic studies on variability and character association in garlic (Allium sativum L.)”. The experiment was executed at Main Experiment, Station of Department of Vegetable Science, NNPG Collage Goda Ayodhya UP during Rabi season 2015-2016, with following objectives (1) To study genetic variability available in different genotypes, (2) to estimate heritability and genetic advance in percent of mean. 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 (%). Analysis of variance for design of experiment revealed that there is significant differences among both blocks and checks. Based on mean performance of genotypes, the NDG-9, NDG-41, NDG-45, NDG-18 and NDG-22 were identified as most promising genotypes for bulb yield per plant and other important traits. High heritability coupled with high genetic advance in percent of mean was recorded for number of cloves per bulb, length of leaf, T.S.S., width of clove and bulb yield per plant. 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.
