在乌兹别克斯坦,棉黄萎病对棉花造成严重损失。为了选育能抗强致病力菌系的棉花品种,需确定棉花对不同地域的强致病力菌系的基因型抗性和F1代的抗性遗传度。研究发现,品种Omad和品系L-44,L-408,L-155,L-1708对所选菌系的抗性最好。当受到侵染时,它们表现出超敏感性,但不表现黄萎病症状。F1代的黄萎病抗性为超显性和显性遗传,且与鉴定方法无关。同时,存在中间性遗传。遗传优势度取决于其亲本的配合力、F1代受侵染时的基因反应型和不同地域菌系的致病力。其中,Omad,С-5621,L-44,L-1708的表型抗性高;在F1代中,组合L-155×С-5621和L1708×С-5621的表型抗性较高,在50%～80%。黄萎病抗性遗传控制的特点是趋向于最好或最差亲本的负或正的超显性、显性遗传以及中间型遗传。对所选菌系,杂交组合L-155×С-5621和L-155×L-44的综合抗性最好。
In Uzbekistan, Verticillium wilt caused serious damage to cotton. In order to breed cotton varieties that can resist strong virulence strains, it is necessary to determine the genotypic resistance of cotton to strong virulence strains in different regions and the heritability of F1 generation. The study found that the varieties Omad and strains L-44, L-408, L-155, L-1708 the best against the selected strains. They show hypersensitivity when infected, but do not exhibit the symptoms of Verticillium wilt. Verticillium wilt resistance in F1 generation was over dominant and dominant inheritance, and had nothing to do with the identification method. At the same time, there is intermediate genetic. The degree of genetic dominance depends on the combining ability of their parents, the gene response type at the F1 generation and the virulence of different geographical strains. Among them, the phenotypes of Omad, С-5621, L-44 and L-1708 were high; in F1, the combination of L-155 × С-5621 and L1708 × С-5621 had higher phenotypic resistance. 50% ~ 80%. The genetic control of Verticillium wilt resistance is characterized by negative or positive overdominance, dominant inheritance and intermediate inheritance toward the best or worst parent. The best combination of L-155 × С-5621 and L-155 × L-44 was selected for the selected strains.
