确保低芥酸油菜商品生产品质的关键措施是保证供种质量和集中连片种植。为保证生产用种的质量,在原种繁殖中一般以建立隔离区,进行严格的空间隔离来繁殖种子。此种方法保纯的效果较好,但在具体布局落实隔离区时,工作量较大。近年来,我们在大面积低芥酸油菜商品生产基地的中心田块进行了繁殖与商品生产同品种的低芥酸油菜原种的研究,还试用早春播种,即时间隔离的方法繁殖原种,取得了较好效果。几种繁殖方法的效果总结于后:
The key measure to ensure low-erucic acid product quality is to ensure quality and contiguous plantation. In order to ensure the quality of the production seed, in the original species breeding in general to establish the isolation zone, the strict space for breeding seeds. This method of pure effect is better, but in the implementation of the specific layout isolation zone, the workload. In recent years, we have conducted researches on the low erucic acid rape seed of the same breed and commodity variety in the center plots of the large-scale low-erucic acid rapeseed production base. We also try to breed the original species by means of early spring sowing, Achieved good results. The effects of several breeding methods are summarized below:
