摘要
以采集于冀东沿海地区的370及黑龙江省的2份野生大豆为材料,利用27对SSR引物进行遗传多样性分析。27个SSR位点扩增出209个多态性带,平均每个位点等位基因数目为7.74个,SSR位点的遗传多样性指数分布范围,Simpson指数为0.3998～0.8358,Shannon-weaver指数为0.7567～1.9879,冀东沿海地区野生大豆材料表现出丰富的遗传多样性。聚类分析结果中冀东靠近海岸线地区的材料与内陆材料之间存在着明显的遗传差异;同一居群的材料遗传距离很近,有些不同居群的材料由于生境相似遗传距离也较近;然而有些同一居群内的材料表现出了明显的遗传分化。
Three hundred and seventy accession of wild soybean,collected from the eastern area of Hebei Province and two accession from Heilongjiang Province were used as materials in this study.Twenty-seven pairs SSR primers were used to analyze the genetic diversity of these materials.Two hundred and nine polymorphic bands were amplified by 27 pairs SSR primers.Genetic diversity index showed that distribution of Simpson index was 0.3998～0.8358,and distribution of Shannon-weaver index was 0.7567～1.9879,which suggestted that wild soybean collected from the eastern area of Hebei Province had abundant genetic diversity.Clustering analysis showed that,the materials collected near the coastline are clearly separated from the materials collected inland region.The genetic distance was very close among the materials in one population and also the materials of different populations because of their similar habitat.However,sometime there were genetics differentiations in a same population.
