摘要
以抗咪唑啉酮类除草剂油菜M9选系M9-2、M9-3、M9-11、M9-14和MI CMS(陆奥-五十铃细胞质雄性不育)恢复系N221、N340、N341为亲本材料配制杂交组合,研究抗性遗传。结果表明,咪唑啉酮抗性为显性性状,由1对核基因控制,抗性基因在F2和BC1群体遵循孟德尔单基因遗传规律。因此,应用杂交、回交等常规育种方法可将抗性基因导入目标品种。
Reciprocal crosses were made between M9 derived lines M9-2,M9-3,M9-11,M9-14 and MI CMS（Mutsu-Isuzu cytoplasmic male sterile） restorer lines N221,N340,N341.The object was to study the inheritance of an imidazolinone resistant Brassica napus mutant M9.In F2 and BC1 populations,the resistance of M9 was shown to be a single,dominant nuclear gene,and fitted Mendel model.This result suggested that the imidazolinone resistance gene in M9 could be transformed to target species by hybridization,backcrossing and other conventional breeding methods.
