利用40对SSR引物对引自俄罗斯远东地区的大豆46份和来自黑龙江省的大豆44份共90份大豆种质资源进行遗传多样性和群体结构分析.结果表明,俄罗斯远东地区大豆遗传多样性高于黑龙江省大豆,UPGMA树状聚类和Structure遗传结构分析将90份材料分为3个类群,每个类群都包括不同地理来源的中、俄大豆,但主体明显:类群Ⅰ、类群Ⅱ主要为俄罗斯远东地区大豆资源,类群Ⅲ主要为黑龙江省大豆资源;中、俄大豆没有明显分开,表明俄罗斯远东地区和黑龙江省大豆种质个体间亲缘关系较近,拓宽黑龙江大豆的遗传基础还需从更大范围内引入俄罗斯种质.
In this study,we characterized a set of 46 accessions of soybean from Russian Far East and 44 ac-cessions from Heilongjiang Province using 40 SSR primers,to evaluate their genetic diversity and population struc-ture.The results showed that,the genetic diversity of soybeans from Russian Far East was higher than that of Hei-longjiang Province.The germplasm resources were divided into 3 clusters by NJ phenogram depicting and Structure software.Each cluster contained accessions from Russia and Heilongjiang,but the majority were likely originated from the same region.The majority of cluster Ⅰ,cluster Ⅱ were the accessions from Russia,and cluster Ⅲ were from Heilongjiang.In the present study,these germplasm resources were not divided in accordance with their geo-graphical origin.It indicated that the relationship between soybean germplasm from Russia and Heilongjiang was close.It was necessary to introduce a wider range of germplasm from Russian Far East to broaden the genetic basis of soybean in Heilongjiang Province.
