以日本白菜品种“绿半白”和韩国抗根肿病品种“白菜王”为试材，通过小孢子培养获得DH自交不亲和系，经5代回交获得BC5代抗根肿病萝卜胞质不育系CCR11239，DH系经6代自交育成CCR11239的保持系CCR11240。以韩国品种“白菜王”与鲁春白1号（83－1）杂交，经5代自交获得自交亲合系CCR11241，经CCR11240×CCR11241，获得新品种CCR11242。该品种经品比试验、省区试和生产示范，每666．7m2平均产量4065 kg，比对照品种鲁春白1号（83－1）增产142％，病情指数（5．63）比对照降低88．13，表现高抗（ HR）。2012年通过新品种登记。

Using Japanese variety Half Green Cabbage ( HGC) and South Korean anti -clubroot variety CR Cabbage King ( CCK) as materials, the DH self -incompatible lines were obtained through microspore culture .After five-generation backcross , CCR11239 , an anti-clubroot radish cytoplasmic sterile line , was obtained.Through six-generation self-crossing of DH system , the maintainer line CCR11240 of CCR11239 was obtained.After the cross of CCK and Luchunbai 1 (83-1), and then five generation self -crossing, the self-compatible line CCR11241 was obtained.Through crossing CCR11240 with CCR11241, the new variety CCR11242 was obtained .Through variety comparison test , provincial regional test and production demonstra-tion test , the new variety registerted in 2012 .Its average yield reached 4 065 kg per 666 .7 m2 , which in-creased by 142%compared with 83-1;the disease index was 5.63, which was 88.13 lower than CK, so it showed high resistance (HR) to clubroot.
