甘蓝型油菜良种“胜利油菜”引入本省种植后,由于抗毒素病力强,产量高而稳定,对本省油菜增产起了显著作用。但胜利油菜生育期过长,成熟过晚,不能适应本省发展多熟制的需要,而生产上迫切要求的是早熟、高产、抗逆性强的新品种。我们根据这一要求,从1958年起开展了甘蓝型油菜早熟品种的选育工作,目前已选育出基本上符合这一要求的新品种“早丰1号”。
After the introduction of rapeseed rape (Brassica napus L.), a good variety of Brassica napus, into the province, the production of rapeseed increased markedly due to its strong resistance to toxins, high yield and stability. However, the rapeseed growth period is too long, mature too late, can not adapt to the development of multi-cooked local needs, and production is urgently required is a precocious, high yield, strong resistance to new varieties. Based on this request, we have carried out the breeding of precocious varieties of Brassica napus beginning in 1958. We have now bred a new variety “ZF No. 1” that basically meets this requirement.
