摘    要:利用8种RAPD引物(OPH-2、OPH-3、OPH-5、OPH-12、OPH-15、OPH-16、OPH-18和OPH-20)对大豆属的21份植物材料,其中包括Glycine亚属的10个种和Soja亚属的3个种,进行了基因组指纹图谱构建。通过对获得的基因组指纹图谱的量化分析,利用Unweightedpairgroupwithmathematicaverage(UPGMA)对大豆属中的各个种进行了亲缘关系重建。重建的亲缘关系表明:G.tomentella种中存在3种不同的进化类型,其分化距离已大于某些种种间的分化距离,它们可能是被形态遮蔽的3个种。Soja亚属内3个种的分化关系同前人的研究推断相同,其亲缘关系很近,这一结果支持将这3个种归并为一个种的观点。但是重建的亲缘关系未能显示出大豆属两个亚属的划分格局。

关 键 词:RAPD指纹图谱,大豆属,亲缘关系

Abstract:Genomic fingerprints of 21 accessions of genus Glycine,belonging to 10 species of subgenus Glycine and 3 species of subgenus Soja,have been constructed with 8 RAPD primers (OPH-2, OPH-3, OPH-5,OPH-12, OPH-15, OPH-16,OPH-18, and OPH-20). By the analysis of the data of the genomic fingerprints,the genetic relationship of the accessions was reconstructed with UMPGA. The reconstructed phylogeny showed that there existed three types in G. tomentella and the genetic distance between them had been more than those between some other species. They might be three cryptic species. The divergence of three species in subgenus Soja was as primary reports. Their genetic relationship were close. The result supports the opinion that the three species should be considered as one.The reconstructed dendrogram of genus Glycine did not showa clear division between two the subgenera.
Keywords:RAPD-fingerprinting  Genus Glycine  Phylogeny
