摘　　要：为分析和挖掘西藏地区油菜籽特征品质,推动西藏油菜高质量发展,选取31份西藏地区与448份长江流域代表性油菜籽样品,分析了油菜籽含油量、脂肪酸和植物甾醇含量,比较了西藏地区与长江流域油菜品质差异。结果发现西藏油菜籽含油量显著高于长江流域冬油菜区,但植物甾醇含量显著低于长江流域冬油菜区。考虑到油菜籽中甾醇含量与芥酸含量呈负相关,在西藏地区取低芥酸油菜籽样品,验证了芥酸含量高是导致西藏地区油菜籽甾醇平均含量低于长江流域的重要原因,并筛选出含油量高于长江流域平均值,甾醇含量高的油菜籽品种新油20、清湘油168、新油17和藏油12号,可作为高甾醇油菜品种在西藏地区推广,对提升西藏地区油菜籽品质、巩固脱贫成果具有重要意义。In order to investigate the distribution of quality parameters of rapeseed in Tibet,explore the quality difference between rapeseeds from Tibet and Yangtze River basin,and clarify the advantageous indexes of rapeseed from Tibet,for selecting high-sterol varieties,we analyzed the oil content,fatty acid and phytosterol content of 31 samples from Tibet and 448 samples from Yangtze River basin in 2021.The results indicated that the average oil content of rapeseeds from Tibet is significantly higher than that of rapeseeds from Yangtze River basin,while the av-erage phytosterol content of rapeseeds from Tibet is significantly lower than that of rapeseeds from Yangtze River ba-sin.Because the sterol content in rapeseed is negatively correlated with erucic acid content,low erucic acid rape-seed was selected in 2022 to verify that the substandard erucic acid is an important cause of the lower average sterol content of rapeseed from Tibetan region than that of rapeseeds from Yangtze River basin,and the double low rape-seed varieties with higher oil content than that in Yangtze River basin and all higher sterol content were screened,including Xinyou 20,Qingxiangyou 168,Xinyou 17 and Zangyou 12,which can be taken as high sterol rapeseed va-rieties,which are of great significance to improve the overall quality of rapeseed and support the consolidation and expansion of the achievements of poverty elimination.
