| 摘 要： | 选用240条随机引物，从中筛选出6条对棕色棉新彩1、新彩2和绿色棉新彩3、新彩4及47个彩色棉品种间杂种作了RAPD多态性分析，并在棕色棉、绿色棉和棕绿彩棉3个水平进行聚类和相似性分析。结果表明，棕色棉之间、绿色棉之间及棕绿彩棉之间的遗传距离和相似性差异不显著，它反映了棕、绿彩棉之间的遗传基础比较狭窄，遗传多样性水平相当。可能是因为共同的基础种质资源、相同的育种目标及相近的育种方法造成此结果。
Abstract:Genetic diversity analysis of brown cotton Xincai 1 and Xincai 2 and green cotton Xincai 3 and Xincai 4 and other 47 color cottons was conducted by the random amplified polymorphism DNA (RAPD) techniques,using 6 random primers.Cluster and similarity analysis of these cottons showed that the differences in genetic relationship and similarity among the brown cottons,green cottons and brown-green cottons are not remarkable.The results also reflect that the genetic bases of the brown and green cottons are narrow,and they are at the same genetic diversity level.These results are probably due to the same basic germplasms,the same breeding aims and the similar breeding approaches.
