Abstract: The examination was conducted to point out genetic diversity of 36 Kabuli chickpea genotypes, including two varieties 6 x 6 in simple lattice design, during the main growing season 2019/2020-2020/2021 in Awabel district for two consecutive years. Thirty-six genotypes were grouped into six (6) distinct groups based on 13 (thirteen) traits. Intragroup distance was maximum in cluster IV (D2 = 438.6, indicating that the genotypes enclosed in this group were diverging as compared to others groups. In descending order maximum inter cluster distance was obtained among cluster VI and IV (D2 = 860. 9), cluster VI and V (D2 = 454.9), between groups II and VI and between groups VI and I. Genotypes that have a large intergroup distance can give a high heterotic response leading to better recombinants. The paramount six principal components elucidate approximately 78.52% of the total variation. Seed yield (0.439), number of seeds plant -1 (0.459) and number of seeds pod-1 (0.368) were the main contributors of variation for (PC1). The current experimental finding shows the presence of a wide range of diversity among the genotypes tested, which is an essential role for further use in the breeding program. However, multi-locus testing among a wider conventional of contestant genotypes is needed to prove the stability across environment and advance good-performing varieties of the existing genotypic diversity.
