利用从秦白2 号中分离出的自交不亲和系9247 作母本,从福山包头中分离出的自交不亲和系92226 作父本育成中晚熟一代杂种高抗2 号。生育期85 ~90 d( 天) ,高抗大白菜病毒病、霜霉病和软腐病,经济性状优良,极耐贮藏,产量105 000 kg·hm - 2 ,较对照鲁白8 号、鲁白10 号分别增产24 .24 % ~45.6 % 和2 .33 % ~7 .08 % 。
Inbred line 9247, which was isolated from Qinbai 2, was used as the female parent. The self-incompatible line 92226 isolated from Fukuyama Baotou was used as the male parent to cultivate the middle-late-mature F1 hybrid with high resistance to 2 number. The growth period was 85-90 d (days), highly resistant to cabbage virus disease, downy mildew and soft rot disease. The economic traits were excellent and extremely resistant to storage. The yield was 105 000 kg · hm -2 compared with that of Lu Bai No.8 White 10, respectively, an increase of 24. 24% ~ 45.6% and 2. 33% ~ 7. 08%.
