油菜是四大油料作物之一,上世纪90年代以前,油菜曾作为宁德市主要冬种作物种植。由于当时推广的大部分油菜品种菜油中的芥酸和菜籽饼中的硫代葡萄糖甙含量高,品质差,不适宜食用和饲用。同时由于种植结构的调整和种植效益低下等原因,油菜面积逐年减少,有些县市基本上没有种植。90年代后,国内一些科研单位相继开展了油菜品质育种研究,先后育成了一大批双低(低芥酸、低硫代葡萄糖甙)油菜品种,显著改善了品质。今冬,宁德福鼎等县、市开始引种甘蓝型双低油菜新品种 Rape is one of the four major oilseed crops. Before the 90s of last century, rape was planted as the main winter crop in Ningde City. Because most of the rapeseed oilseed rapeseed oil and rapeseed cake in the promotion of the high content of glucosinolates, poor quality, unsuitable for food and feed. At the same time, the area of ​​rapeseed decreased year by year due to the adjustment of planting structure and the low benefit of planting, and some counties and cities basically did not grow. After the 1990s, some domestic research institutes successively conducted researches on rapeseed quality breeding and successively cultivated a large number of double low (low erucic acid, low glucosinolate) rapeseed varieties, which significantly improved their quality. This winter, Ningde Fuding other counties, the city began to introduce new varieties of cabbage double canola
