用5个不同来源的有色纤维陆地棉材料(3个棕色棉、2个绿色棉)与2个白色棉配制10个杂交组合,分析其后代的纤维颜色遗传情况。试验表明,陆地棉有色纤维性状受不完全显性单基因控制。同时采用经测验具有良好等基因性的两对近等基因系,研究有色纤维基因对产量、品质等共15个性状的影响。结果表明,有色纤维基因对皮棉产量、衣分、纤维长度、比强度、麦克隆值、抗病性有负效应,对子指有正效应,影响程度与遗传背景有关,对子棉产量、铃重、单株成铃、株高、果枝数等性状无明显不良反映。但结合有效选择,通过杂交、回交等方法对原有色棉亲本的产量、品质性状可有一定程度的改良
Five hybrid crosses were made from five different sources of colored fiber upland cotton (three brown cotton and two green cotton) and two white cottons to analyze the fiber color inheritance of their offspring. The results showed that the non-dominant single gene control of non-ferrous fiber in upland cotton. At the same time, two pairs of near-isogenic lines with good isogenicity were tested to study the effects of colored fiber genes on 15 traits such as yield and quality. The results showed that the genes of colored fiber had a negative effect on lint yield, lint percentage, fiber length, specific intensity, micronaire value and disease resistance, positive effect on sub-finger, and the degree of influence was related to genetic background. Heavy, bolls per plant, plant height, number of fruit branches and other traits without significant adverse reactions. However, in combination with effective selection, the yield and quality traits of the original colored cotton parents can be improved to some extent by means of hybridization and backcrossing methods
