选取5个甘蓝型春油菜品种，在甘肃省具有代表性的地区渭源、天祝、秦王川、临夏、甘南等地种植，对其品质进行分析。结果表明:主要脂肪酸中以芥酸含量在种植地区间平均变异系数最大(173.92%)，亚麻酸含量在种植地区间平均变异系数较大(18.58%)，而其余组分在种植地区间平均变异系数相对较小。硫苷含量、蛋白质含量在种植地区间平均变异系数相对较大(分别为27.30%、7.26%)，而含油率在地区间平均变异系数最小(3.17%)。方差分析结果表明，主要脂肪酸中除了芥酸和亚麻酸含量地区间差异不显著外，油酸、亚油酸、饱和脂肪酸含量差异显著；蛋白质含量在地区间差异显著；含油率、硫苷含量地区间差异不显著。

Selecting five cultivars of Brassica napus， planting respectively in Weiyuan， Tianzhu， Qinwangchuan， Linxia， Gannan of Gansu province. The test is carried out in a completely randomized design， the quality and yield of rapeseed are analyzed. The result shows that the erucic acid content of major fatty acids is 173.92%， which is the biggest on the average coefficient of variation and linolenic acid content is 18.58%， which is larger on the average coefficient of variation in planting area and other components is small on the average coefficient of variation relatively. The average coefficient of variation of glucosinolates， protein is relatively larger(27.30%， 7.26%)， while the mean variation coefficient of oil content in the planting area is the smallest(3.17%). Analysis of variance showed that the erucic acid and linolenic acid was not significant between planting areas ，oleic acid， linoleic acid， saturated fatty acid is significant； protein is significant between the planting areas， and oil content， glucosinolate have no significant difference.
