Abstract: In this study genetic diversity of 39 Allium sativum L. genotypes collected from different parts of Iran was investigated by using morphological characteristics. Measuring of characteristics of garlic genotypes were performed based on IPGRI descriptor. Analysis of variance showed that all of the characters in examined genotypes were significant, showing high variability in characters. Also factor analysis was used for determining the number of main factors. Factor analysis showed that most bulb characters were composing the main factors. Effective characters categorized in seven factors that contributed 81.84% of total variance. For each factor eigen value more than 0.6 was used as significant eigen value. Cluster analysis was performed using these seven factors and genotypes in distance of 10 (similarity coefficient) were divided four main clusters. This study showed that multivariate analysis methods could be a useful method for discrimination of garlic genotypes.
