本文系统总结了本研究室从 1982年起开展棉花黄萎病抗性遗传育种所取得的一些研究结果。18年 4个轮次的研究证明 ,棉花黄萎病抗性表现为多个显性单基因的遗传模式 ,从而基本上澄清了国际上长期争论的难题。通过我国黄萎病病原菌的遗传变异和致病力分化分析 ,提出了棉花抗黄萎病育种中鉴别菌株的选择 ,抗源的合理利用 ,苗期快速鉴定等选育技术 ,拓建了抗黄萎病育种的轮回选择基础群体。选育出早熟、高产、优质、抗枯耐黄萎病棉花新品种南农 1号在生产上推广利用
This article systematically summarizes some of the research results obtained from 1982 in the field of genetic breeding of Verticillium dahliae resistance in our lab. Four rounds of 18 years of research have shown that the resistance of cotton to Verticillium wilt showed multiple dominant single-gene patterns of inheritance, thus basically clarifying the long-standing international controversy. Through the analysis of the genetic variation and pathogenicity differentiation of Verticillium wilt pathogen in China, this paper proposed the selection of strains for identification of Verticillium dahliae resistance in cotton, the rational use of anti-verticillium, the rapid identification of seedling stage, Reciprocal selection of wilt breeding base groups. Breeding of a new cotton variety Nongnong 1 with early maturity, high yield, good quality and resistance to Verticillium wilt was popularized in production
