Abstract

RAPDs analysis was used to assess the genetic diversity of some elite cotton varieties. 17 cotton varieties or breeding lines were screened with 200 arbitrary primers to generate 113 polymorphic bands. Cluster analysis and UPGMA showed that 17 varieties could be put into 3 clusters corresponding to genome difference. The genetic similarity among them ranged from 0.2000 to 0.8451. Three elite varieties Ejing-1, Sumian-3 and Zhongmiansuo-12 are highly similar in genetic base. 7581, an offspring from Gossypium hirsutum x G. hirsutum race Latifolium, is distinct from other upland cotton varieties. A trend in germplasm usage in the same research center was also shown in the study. To sustain progress in genetic improvement, we suggest that some good gene from other species should be considered in the upland cotton breeding procedure.
