In order to study genetic diversity in garlic (Allium sativum), 18 genotypes of this plant were evaluated in a randomized complete block design with three replications at Research Farm of Faculty of Agriculture, Shahed University. The studied traits were corm shape, cormlet shape, corm weight, number of leaves at maturity, total leaf weight per plant and ratio of corm weight to total plant weight. Results of simple analysis of variance showed significant differences among genotypes for 6 traits (p≤0.01).The correlation between total weight of each plant with leaf and number of leaves at harvest time and corm weight was significant at 1% probability level.
