摘要: 利用31个SSR引物分析56份俄罗斯远东地区春小麦(Triticum aestivum)及56份黑龙江省2010生(区)试品系的遗传变异和群体结构。结果表明, 黑龙江省春小麦和俄罗斯远东春小麦明显分化为两大类群, 聚类结果同地理来源的划分基本一致; 居群间和个体间都存在显著性差异; 群体的遗传分化程度较高, 但群体间的基因交流有限, 血缘相对比较单一。鉴于部分黑龙江省同一育种单位的品种(系)间的遗传距离非常相近, 目前亟需拓宽和创制新的小麦种质资源。实验结果证明种质资源遗传多样性与地理来源和人为选择压力密切相关。

Abstract: To evaluate the genetic diversity and population structure of wheat germplasm in the far east of Russia and Heilongjiang Province of China, we characterized a set of 56 accessions of spring wheat from Russia and 56 strains of spring wheat from regional and production tests in 2010 from Heilongjiang province using 31 single-sequence repeat primers. The germplasm resources were divided into 2 clusters, which agreed with their geographical origin. Highly significant variance was found for both populations and individuals. The level of genetic differentiation was high and the gene flow was low. We found close genetic distance among strains in the same breeding institutions of Heilongjiang province, so the genetic resources must be broadened. The genetic relationship and diversity of wheat are closely associated with their geographical origin and selection pressure by humans.
