摘要
对我国引进和育成的52个抗枯、黄萎病品种的系谱及其对产量性状的影响进行分析,结果表明岱字棉与斯字棉血统在52个品种中占有较大的比例,其次是福字棉,而其他品种的血统较少。根据几个主要种质在不同品种中所占的比例进行聚类分析,可将52个品种分为4类。系谱组成不同对品种产量性状具有一定的影响,尤其对单铃重和子指影响较大。含有较大比例岱字棉血统的第一类品种单铃重明显高于含有较小比例岱字棉血统和部分斯字棉血统的第二类品种;第一类品种的子指也明显高于第二类品种和含有较大比例斯字棉血统的第四类品种。
Fifty-two China-bred and introduced cottons with Fusarium and Verticillium wilts resistance were used to study their pedigrees and the effects of pedigree proportion on yield components. The results indicated that Deltapine and Stoneville descents contributed to the most of the varieties in proportion, followed by Foster. According to the proportion of main germplasm resources in different cottons,52 varieties were classified into four groups. Different genealogy composition had different effects on yield components, especially on boll weight and seed index. The varieties of first group with higher proportion of Deltapine had higher boll weight than those of second group with lower proportion of Deltapine and higher proportion of Stoneville. The seed index of the first group was higher than that of the second and the fourth group with higher proportion of Foster.
