Faba bean is one of the oldest legume crop grown around the world for its cheap source of protein and for being used in crop rotation with cereals to improve soil fertility through nitrogen fixation. This study was designed to determine the extent and pattern of genetic diversity and relationships among 48 Ethiopian faba bean genotypes using 37 SNPs loci based on Kompetitive allele specific PCR SNP markers. Thirty-six SNPs were found polymorphic and revealed an average of 95.6% polymorphisms. The gene diversity ranged from 0.16 to 0.50 with a mean of 0.42 and the PIC value ranged from 0.14 to 0.38 with a mean of 0.33. The Bayesian clustering model grouped the genotypes into two genetically distinct clusters with certain degree of admixture, indicating the introduction of chromosomes of different ancestry and allele frequency. The result clearly showed the presence of relatively high genetic diversity among faba bean genotypes grown in Ethiopia. Thus, these genotypes can be used in faba bean breeding programs to develop farmer preferred cultivars with desirable traits.

蚕豆是世界上最古老的豆类作物之一，其廉价的蛋白质来源，与谷物一起用于作物轮作，通过固氮提高土壤肥力。本研究旨在根据竞争竞争性等位基因特异性PCR SNP标记，使用37个SNP位点确定48种埃塞俄比亚蚕豆基因型之间的遗传多样性程度和模式以及相互关系。发现36个SNP是多态的，并且揭示了平均95.6％的多态性。基因多样性的范围为0.16至0.50，平均值为0.42，PIC值的范围为0.14至0.38，平均值为0.33。贝叶斯聚类模型将基因型分为具有一定混合度的两个遗传上不同的簇，表明引入了不同血统和等位基因频率的染色体。结果清楚地表明，埃塞俄比亚种植的蚕豆基因型之间存在较高的遗传多样性。因此，这些基因型可用于蚕豆育种计划，以发展具有理想性状的农民偏爱的品种。
