[Genetic diversity analysis of brown cotton and green cotton].
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.
