The objective of this study was to examine the genetic diversity present among 297 common bean genotypes using 2554 SNPs and 12 insects and seed-related traits. The phenotyping was done under laboratory condition while the genotyping was conducted by using the Illumina SNP BeadChip. High phenotypic diversity among traits were recorded, ranging from 0.87 to 0.96, with a mean of 0.92. Principal component and discriminant analyses identified four PCs and three discriminant functions, which explained 82% and 100% of the total phenotypic variations among genotypes, respectively. Polymorphic Information Content ranged from 0.21 to 0.38, with a mean of 0.34. The mean gene diversity among genotypes ranged from 0.24 to 0.50, with a mean of 0.44. Genetic distance ranged from 0.19 to 0.82, with a mean of 0.62, while the phenotypic distance ranged from 0.00 to 1.00, with a mean of 0.64 were observed aamong genotypes. The analysis of molecular variance revealed highly significant differences (p<0.001) among and within individuals and among populations. Both the SNP and the phenotypic markers grouped the 297 genotypes into two major distinct clusters and three sub-clusters. This information is useful for identification and development of common bean germplasm with economically valuable traits and the conservation and utilization of genotypes.

这项研究的目的是使用2554个SNP和12种昆虫以及与种子相关的性状，研究297种常见豆基因型之间的遗传多样性。表型是在实验室条件下完成的，而基因型则是通过使用Illumina SNP BeadChip进行的。记录到性状之间的高表型多样性，范围从0.87至0.96，平均值为0.92。主成分和判别分析确定了四个PC和三个判别函数，分别解释了基因型之间总表型变异的82％和100％。多态信息内容的范围为0.21至0.38，平均值为0.34。基因型之间的平均基因多样性范围为0.24至0.50，平均值为0.44。遗传距离范围为0.19至0.82，平均值为0.62，而表型距离范围为0。在基因型中观察到00至1.00，平均为0.64。分子方差分析显示出很大的差异（p <0.001）在个人之间和内部以及人群之间。SNP和表型标记都将297个基因型分为两个主要的不同簇和三个亚簇。这些信息对于识别和发展具有经济价值的普通豆种质以及基因型的保存和利用非常有用。
