| 摘 要： | 对陆地棉 96个品种 (系 )的 1 3个性状进行了方差、遗传相关、系统聚类分析 ,结果表明 :各性状材料间差异显著 ,性状间存在不同程度的遗传相关 ;产量性状间相关度高 ;产量与纤维品质间相关性较低 ,与纤维强度几乎无相关性。根据遗传距离对参试材料进行系统聚类 ,聚为五类 ,第四类群材料丰产优质 ,经选择可作为优良杂交亲本应用

| Abstract: | Variance,genetic correlation and system cluster of 13 characters of 96 upland cotton genotypes were analysed. The results showed that there was a significant differences in genotypes and different genetic correlation in characters. There are strong correlation in yield characters. Yield had little correlation with fiber characters, especially with fiber strength.The 96 genotypes were grouped into five genetic clusters. The fourth genetic cluster gives higher yield and fiber quality, some of them could be selected as high fiber quality parents. [WT5HZ] |
