华杂2号为我校育成的甘蓝型低芥酸雄性不育三系杂交种,由低芥酸雄性不育系1238A和低芥酸恢复系85-恢10配制而成,其芥酸含量为1~2%,属优质杂交种。目前已在湖北省进行多点试种、示范。经过1988和1989两年25个点次正规试验,比高芥酸(芥酸含量40~50%)当家品种821增产2.5 Huacha II bred low-erucic acid male sterile three-line hybrid bred in our school was prepared from low erucic acid male sterile line 1238A and low erucic acid restorer line 85-Hui 10 formulated with erucic acid content 1 ~ 2%, is a high quality hybrids. Has been in Hubei Province for more trial, demonstration. After 25 times of regular test in 1988 and 1989, the yield was increased by 2.5% compared with the high erucic acid (erucic acid content 40 ~ 50%)
