华杂系列杂交油菜是华中农业大学农学系油菜研究室傅廷栋教授等利用自己首次发现的波里马细胞质雄性不育材料选育出的系列甘蓝型油菜杂种,如华杂2号、华杂3号和华杂5900等。华杂2号是由低芥酸甘蓝型油菜细胞质雄性不育系1238A 和恢复系“85—10”配制的低芥酸杂种,1992年通过湖北省品种审定委员会审定,是我国第一个通过审定的低芥酸甘蓝型油菜细胞质雄性不育三系杂种。1995年获湖北省科技进步一等奖。其芥酸含量为0.15%-1.60%,一般每公顷产2250Kg 以上。比中油821增产5%-10%。华杂2号生长势强,特别是苗期早生快发,发根力强,有利于“秋发”、“冬发”栽培:抗寒能力强:耐菌核病能力 Huacha series of hybrid rape is Huazhong Agricultural University, Department of Agronomy, Professor Fu Tingdong, rapeseed and other researchers using their own first found Polima cytoplasmic male sterile material breeding series of Brassica napus hybrids, such as Hua Za 2, Hua Za 3 And China Miscellaneous 5900 and so on. Hua-za 2 is a low-erucic acid hybrid prepared from low-erucic acid (Brassica napus L.) cytoplasmic male sterile line 1238A and restorer line “85-10”. It was approved by Hubei Provincial Commission for Variety Approval in 1992 and was the first in China Approved cytoplasmic male sterile three-line hybrids of Brassica napus. In 1995 won the first prize of scientific and technological progress in Hubei Province. Its erucic acid content of 0.15% -1.60%, usually more than 2250Kg per hectare. 821 than the oil yield 5% -10%. Huasha 2 growing strong, especially the early seedling quick hair, strong hair root, is conducive to “autumn hair”, “winter hair ” cultivation: cold ability: resistance to sclerotinia
