| 摘 要： | 用随机扩增多态DNA标记(RAPD)技术对华中农业大学薯蓣资源圃中收集的11个盾叶薯蓣居群及4个薯蓣属植物居群的混合样品进行了遗传多样性的检测。对于11个盾叶薯蓣居群,19个RAPD引物扩增出153条带,其中113条为多态带,占73.86%。UPGMA聚类分析结果揭示了各居群间的亲缘关系。

| Abstract: | Random amplified polymorphic DNA(RAPD) were applied to detect genetic diversity of bulking samples of 11 Dioscorea zingiberensis populations and 4 other Dioscorea populations from Dioscorea resources plot of Huazhong Agricultural University. For the 11 Dioscorea zingiberensis populations, 19 RAPD primers produced 153 bands, out of which 113 bands were polymorphic. The rate of polymorphic bands accounted for 73.86% of the total amplified bands. UPGMA (Un-weighted Pair Group Mathematics Average) clustering analysis displayed the genetic relation of populations. |
