| 摘 要： | 利用甜瓜茎蔓无刚毛突变体与茎蔓光滑无毛突变体进行杂交,对F1,BC1,BC2,F2代植株茎蔓性状观察统计发现:F1代表现茎蔓正常有刚毛;BC1代植株性状表现为茎蔓正常有刚毛、茎蔓无刚毛;BC2代植株性状表现为茎蔓正常有刚毛、茎蔓光滑无毛,其分离比值均接近1∶1;F2代植株性状表现为茎蔓正常有刚毛、茎蔓无刚毛、茎蔓光滑无毛3种类型,经X2检验符合9∶3∶4的分离规律,说明茎蔓无刚毛基因和茎蔓光滑无毛基因表现为非等位基因,甜瓜茎蔓光滑无毛基因对无刚毛基因存在隐性上位作用。

| Abstract: | Cross were made between two mutation line of melon hairless and glabrous on stem and foliage,and the stem and foliage character were observed in its F1,F2,BC1 and BC2 generations,the results indicated that F1 plants are normal,the ratio of BC1 and BC2 progenies segregated normal : hairless and normal : glabrous are almost 1 ∶ 1,the plant performance of F2 have three types:normal,hairless and glabrous. The ratio are 9 ∶ 3 ∶ 4 according to the Chi squre(X2)test. It indicated that the genes resulting in glabrous and hairless on stem and foliage are non-allelic,and interaction existed in the two genes,and the gene of glabrous epistatic to the gene of hairless. |
