用我国发现的4个陆地棉Gossypium hirsutum L.)核雄性不育系和6个常规品种配制了24个杂交组合,对19个性状进行了分析。结果表明,阆A在皮棉产量方面,81A在纤维品质和早熟性方面具有较高的一般配合力效应,为较理想的亲本。与常规品种相比,不育系的特殊配合力方差较小。对产量因素和纤维品质性状的遗传参数估计表明,多数产量因素以加性遗传效应为主,杂种一代表现为部分显性;而多数纤维品质性状则以显性效应为主,加性效应次之,这与常规品种×常规品种的遗传效应有所不同。 Twenty-four crosses were made from the four Gossypium hirsutum L. male sterile lines and six conventional cultivars found in China. Nineteen traits were analyzed. The results showed that 阆 A had a higher general combining ability in fiber quality and precocity in terms of lint yield, which was the ideal parent. Compared with the conventional varieties, the variance of the special combining ability of sterile lines is smaller. The genetic parameters of yield and fiber quality traits showed that most of the yield factors were additive genetic effects, while the hybrids showed partial dominance. However, most of the fiber quality traits were dominated by the dominant effect and the additive effect was the second , Which is different from the conventional varieties × conventional varieties of genetic effects.
