The genetic diversity of two wild diploid wheat species, Triticum monococcum var. boeoticum and T. urartu, was assessed using starch gel electrophoresis. Genetic diversity is uniformly low in both species. Number of alleles per locus was very low with a mean of 1.22 for T. monococcum var. boeoticum and 1.19 in T. urartu. Percentage of polymorphic loci was also low, with a mean of 19.71 for T. monococcum var. boeoticum and a mean of 18.35 for T. urartu. Mean gene diversity was low with a mean of 0.052 in populations of T. monococcum var. boeoticum and a mean of 0.040 in populations of T. urartu. Genetic affinities of the species and of populations were computed using Nei's identity index (NI). Overall genetic affinities of the two species are NI=0.697. The genetic affinities of different populations of a species are uniformly high with NIs ranging from 0.894 to 1.000 in T. monococcum var. boeoticum and from 0.898 to 1.000 in T. urartu.
采用淀粉凝胶电泳技术对两种野生二倍体小麦种，即节节麦（Triticum monococcum var. boeoticum）和粗山羊草（T. urartu）的遗传多样性进行了评估。两个物种的遗传多样性均较低。每个位点的等位基因数非常低，节节麦的平均值为 1.22，粗山羊草的平均值为 1.19。多态性位点的百分比也较低，节节麦的平均值为 19.71%，粗山羊草的平均值为 18.35%。基因多样性平均值也较低，节节麦种群的平均值为 0.052，粗山羊草种群的平均值为 0.040。利用 Nei 的身份指数（NI）计算了物种和种群的遗传相似性。两个物种的总体遗传相似性为 NI=0.697。一个物种的不同种群的遗传相似性均较高，节节麦的 NI 值范围为 0.894-1.000，粗山羊草的 NI 值范围为 0.898-1.000。
