近三十年来,加拿大的油菜生产发展迅速。同时,食用油和饼粕的品质等人们关心的问题也逐步提到了议事日程上。为了解决这些问题。育种家开始研究改变食用油和饼粕化学成分的可能性,以便使菜油和饼粕更受欢迎。1961年和1967年,菜油中芥酸含量和种子中硫代葡萄糖甙含量的遗传控制分别获得成功。1979年,加拿大生产的所有油菜几乎都是低芥酸的,三分之二的油菜也是低硫的。这些优质品种的商品名称为卡诺拉油菜(Canola)。卡诺拉油菜育种计划的主要目标仍是提高产量和改善品质。加拿大的油菜育种与其他国家不同,其重点放在改进品质上。
Nearly three decades, Canada’s rapeseed production has developed rapidly. At the same time, issues of concern to the quality of cooking oil and cake have also been gradually brought to the agenda. In order to solve these problems. Breeders are starting to study the possibility of changing the chemistry of cooking oil and meal to make vegetable oil and cake more popular. In 1961 and 1967, the genetic control of erucic acid content in rapeseed oil and glucosinolates in seeds were successful. In 1979, almost all canola produced in Canada was low-erucic acid, and two-thirds of the rapeseed was also low-sulfur. The trade names for these premium varieties are Canola. Canola rapeseed breeding program’s main goal is still to increase production and improve quality. Canada’s rapeseed breeding is different from other countries, its emphasis on improving quality.
