| 摘 要： | 通过天然红叶绿色棉和绿叶白色棉的杂交，统计分析F1，F2代叶与纤维色泽的遗传分离规律，以及色素对纤维生长的影响。验证了红叶色素和绿色长绒色素性状是由两对位于两条染色体上，由独立遗传的不完全显性基因控制；而绿短绒为完全显性遗传，并且与绿长绒性状位于同一染色体上，由两对非等位基因控制，其遗传距离为1.26 cM。同时, t测验统计分析结果显示，绿纤维棉株的衣分和绒长极显著低于白色棉，说明纤维中绿色色泽有阻碍棉花纤维生长发育作用；红叶对铃重与铃数以及纤维长度和衣分都没有显著影响。因此，在改良彩棉纤维色泽的同时要与提高纤维品质研究相结合，达到共同提高的目的。 |

| Abstract: | To provide insights into improvements in yield and fiber quality of colored cotton,the experiment for investigating the inheritance of naturally colored cotton was carried out.It was indicated by a comprehensive genetic analysis on natural red leaf,green lint and fuzz,traits of red leaf and green lint were controlled by one pair of genes incomplete in dominance on non-homologous chromosomes,respectively.Green fuzz was controlled by one pair of complete dominant gene and located at the same chromosome with g... |
