比克氏棉及其杂种后代的RAPD分析
RAPD Analysis of Gossypium bickii and Its Hybrid Descendents
摘要
Abstract
The interspecific hybrids were derived from ［(Gossypium arboreum×Gossypium bickii) × Gossypium hirsutum］, (G. arboreum×G.bickii)×Gossypium barbadense］, ［(G. arboreum×G. bickii) × (G.hirsutum×Gossypium mustelinum)］, (G. arboreum×G.bickii) × (G. hirsutum×Gossypium tomentosum)］ after doubling F_1 of (G. arboreum×G.bickii). These hybrids and their parents were analyzed by RAPD. The results showed that: （1）There were 127 amplified DNA bands from 15 primers, 102 bands (80.3 %) were polymorphic; (2) Parents bands and specific bands of hybrids were detected in hybrids; (3) The cluster analysis of materials was studied by group-average method from SAS software. Cluster analysis revealed that these materials were divided into 3 groups. All the results verified the authenticity of hybrids.关键词
