The experiment was conducted at horticulture research farm Dhampur Bijnor during winter season 2019-2020. In the present investigation 21 genotypes of garlic (Allium sativum L.) were evaluated in RBD with the objective of estimating the genetic variability and determination of association among different attributes with each Other and with bulb yield. On the basis of mean performance, the genotype G-41 was the highest yielder followed by G-384. Bareilly local and minimum was found in G-282. Based on mean performance G-189, G-323. G-01 and NG- 3181 were identified as high yielders for bulb yield per plant. These genotypes may further be utilized in breeding programme aimed at improving bulb yield in garlic. Analysis of variance indicated presence of considerable variability for all the twelve characters. The estimates of phenotypic co-efficient of variation (PCV) were higher than the genotypic co-efficient of variation (GCV) for all the characters. High GCV and PCV were observed for Number of cloves per bulb, Polar diameter, weight of dry bulb, and weight of fresh bulb, width of leaf and length of leaves.
