牡丹籽是一种新型的富含亚麻酸（ALA）的食用油资源。为研究花粉源对凤丹牡丹籽油品质的影响，本研究对凤丹牡丹与30个品种杂交的种子脂肪酸进行了监测和评价。结果表明，总脂肪酸和ALA的含量分别为21.23 ~ 29.68%和46.75 ~ 64.71%。30种组合被分为4类。聚类IV田香金、周班红、向阳红和玉洁的杂交种子ALA和不饱和脂肪酸含量最高，平均分别为159.39mg（-1）和263.76mg(-1)，是较好的花粉供体。本研究为选育油脂含量和食用必需脂肪酸含量优良的油菜新品种提供了良好的基础。
Tree peony seed is a novel resource of edible oil with high -linolenic acid (ALA) content (>40%). To assess whether pollen sources influence the seed oil quality, fatty acids of hybrids from the combination of Paeonia ostii Feng Dan' and 30 cultivars were monitored and evaluated in this study. The results indicated that the content of total fatty acid and ALA ranged from 21.23 to 29.68% and from 46.75 to 64.71%, respectively. Thirty combinations were classified into four clusters. Cluster IV including Tian Xiang Jin', Zhou Ban Hong', Xiang Yang Hong' and Yu Jie' were good pollen donors because their hybrid seeds possessed the highest contents of ALA and unsaturated fatty acids, with an average of 159.39mgg(-1) and 263.76mgg(-1), respectively. This study provides a good base for breeding new cultivars with excellent edible oil and essential fatty acid contents for food.
