采用棉属种间杂交新方案,快速获得陆地棉×斯特提棉种间杂交可育杂种,经两次回交后,在枯黄萎病圃扩大群体,稳定性状,人工选择,在育成新品种秦远4号的同时,还选育出抗病优质、抗病高强、抗病大铃、抗病高衣分、抗病抗旱和抗枯黄萎病新种质6类24份。提出了创造新种质的方法。 A new cotton interspecific hybridization program was adopted to rapidly obtain fertile cross between interspecific hybrids of upland cotton × Sterne. After two backcrosses, the population was expanded in the nurture of Verticillium wilt, stable characters and artificial selection. After breeding new varieties of Qin Far from the 4th, we also breed 24 types of new germplasms with high quality, high disease resistance, large disease resistance, high resistance to disease, drought resistance and resistance to Verticillium wilt. Proposed a way to create new germplasm.
