摘　　要：利用3个甘蓝型油菜萝卜质雄性不育系(X2008A、X2011A、XYZ2A)及相应保持系(X2008B、X2011B、XYZ2B)分别与恢复系W01R和W02R杂交,得杂种F_1代。以沣油520为对照,通过组合鉴定试验,分析萝卜质雄性不育胞质对杂种F_1代的产量、农艺性状、品质性状及抗病性等方面的影响。结果表明:2个恢复系W01R和W02R的恢复力强,所配的组合F_1代的恢复率均达100%,说明2个恢复系均适用于本试验;在参试的12个组合中,有10个组合比对照增产,其中用恢复系W01R所配的4个组合(X2008A×W01R、X2008B×W01R、XYZ2A×W01R、XYZ2B×W01R)增产达显著或极显著水平,说明W01R配制的组合比W02R具有更强大的杂种优势;不育胞质和可育胞质对杂种F_1代各性状影响的分析结果表明,除对株高有明显降低效应外,不育胞质对产量、其他主要农艺性状及芥酸、硫苷和含油量无明显影响,但有降低油酸含量效应,对菌核病和病毒病的抗性均无明显影响。Three Brassica napus male sterile lines of ogu cytoplasmic male sterile(X2008A,X2011A and XYZ2A)and their maintainer lines(X2008B,X2011B and XYZ2B)were crossed with the restorer lines W01R and W02R respectively,to get the hybrid F1generation.Then the F1was compared with the control variety Fengyou520,to analyze the effects of radish male sterile cytoplasm on yield,agronomic traits,quality traits and disease resistance in hybrids.The results showed that:The recovery abilities of the two restorer lines W01R and W02R used in this study were strong,the recovery rate of F1generation reached100%,indicating that both restorer lines were suitable.In the12combinations of the tests,the yields of10combinations were significantly higher than those of the control,and the yields of four combinations with the W01R(X2008A×W01R,X2008B×W01R,XYZ2A×W01R and XYZ2B×W01R)were significantly higher than those of the control,indicating that the combinations with W01R had a stronger heterosis than the combinations with W02R.The sterile cytoplasm had no significant effect on the yield and the main agronomic traits,but the plant height reduced significantly.The sterile cytoplasm had no significant effect on erucic acid,glucosinolate and oil content,but reduced oleic acid content.The resistance to sclerotinia rot and virus disease was no significantly affected by the sterile cytoplasm.
