选用８１种随机引物，利用ＲＡＰＤ技术对１３种栽培大豆品种的基因组ＤＮＡ多态性进行了分析，结果表明大多数的随机引物均得到了良好的ＰＣＲ扩增结果，显示出不同的栽培大豆品种之间基因组ＤＮＡ既有高度的同源性，又具有良好的多态性．通过Ｎｅｉ氏遗传共享度分析，使用ＵＰＧＭＡ（ｔｈｅｕｎｗｅｉｇｈｔｅｄｐａｉｒｇｒｏｕｐｍｅｔｈｏｄｆｏｒａｒｉｔｈｍｅｔｉｃａｖｅｒａｇｅｓ）进行聚类分析，得到了ＵＰＧ－ＭＡ系统树和实验材料之间的遗传关系．
Eighty-one random primers were used to analyze the genomic DNA polymorphisms of thirteen cultivated soybean cultivars by RAPD. The results showed that most of the random primers obtained good PCR amplification results, which showed that different varieties of cultivated soybean Between the genomic DNA both highly homologous, but also has a good polymorphism. By Nei's genetic sharing analysis, UPGMA (theunweightedpairgroupmethodforarithmeticaverages) was used for cluster analysis, and the genetic relationship between the UPG-MA phylogenetic tree and the experimental materials was obtained.
