1983～1985连续三年对甘兰型低芥酸油菜田间隔离保纯繁育技术进行了研究。结果表明:①低芥酸油菜品种在田间种植时其芥酸含量高低与同高芥酸油菜品种相隔远近呈负相关。相邻种植的群体含芥量为1.62％,相距500米的群体含芥量为0.27%。②采用纸袋、纱布、尼龙网罩等不同保纯用具对低芥酸油菜品种芥酸含量都能起到良好的保纯作用,但都各有其最佳的使用条件和范围。
From 1983 to 1985, the isolation and pure breeding technology of Canola type low erucic acid rapeseed was studied in field for three consecutive years. The results showed that: (1) The content of erucic acid in low erucic acid rape cultivars was negatively correlated with the high erucic acid rape cultivars in the field. Adjacent planting groups mustard content of 1.62%, 500 meters away from the group mustard content was 0.27%. ② The use of paper bags, gauze, nylon mesh hood and other different pure appliances on erucic acid content of low-erucic acid rapeseed species can play a good role in maintaining pure, but all have their best conditions and scope of use.
