我国开展低芥酸油菜育种工作的时间很短,但进展较快,1984年已筛选出10多个新品系参加全国区试。为了加速其推广,根据我们三年来的经验,应抓好以下几个问题: 一、建立完善的良种繁育体系甘兰型油莱属常异交作物,品种间异交率在10—30%左右;且油菜种子细小、园滑,易引起生物学和机械混杂,尤其在当前高、低芥酸油莱品种更换交替时期,低芥酸油菜大田种植一年后,由于芥酸升高,不能再作种用。为了保证商品菜籽质量,必须建立适 In China, the work of low erucic rape breeding was very short, but the progress was rapid. In 1984, more than 10 new strains were screened out for the national district test. In order to speed up its promotion, according to our experience in the past three years, we should pay attention to the following questions: First, to establish a sound system of seed propagation Brassica oleracea often outcrop crops, varieties between the rate of about 10-30% ; And rapeseed seeds small, slippery, easy to cause biology and mechanical mixed, especially in the current high, low erucic acid oil varieties to replace the alternating period of low erucic acid rapeseed field planting a year later, because of erucic acid, can no longer For planting. In order to ensure the quality of the product rapeseed, it must be established
