| 摘 要： | 以6个在黑龙江省大面积推广的高油或高蛋白大豆品种(垦农4号、垦农18、垦农19、垦农21、垦农22、垦农30)与6个转基因抗除草剂品种(TSB1~TSB6)进行杂交,对杂交后代F1、F2、F3和BC1的抗除草剂特性进行了遗传分析并对每个世代抗感比进行统计分析。结果表明:抗除草剂基因在F2代开始分离,各世代抗感比为F2代3∶1、F3代5∶1、BC1代1∶1,符合孟德尔遗传规律,表明抗除草剂基因由1对显性基因控制。

| Abstract: | Six high-quality soybean varieties(Kennong 4,Kennong 18,Kennong 19,Kennong 21,Kennong 22 and Kennong 30)largely promoted in Heilongjiang Province were used to conduct the direct and reciprocal crosses with six transgenic herbicide-resistant varieties(TSB1-TSB6).The genetic analysis of herbicide-resistant for F_1,F_2,F_3 and BC_1 generation were conducted,and the ratio of resistant and non-resistant plant in each generation were 3: 1,5: 1 and 1: 1.Results indicate that herbicide-resistance was controlled by a dominant gene and it could be explained by Mendelian genetic principles. |
