【目的】

分析科尔沁沙地元宝枫种仁含油率和油脂组分的变异特征，筛选油用价值高的种质资源。

【方法】

以科尔沁沙地3个种源地采集的92株丰产母树种子为材料，测定种仁含油率及脂肪酸组分与含量，采用方差分析、相关性分析等方法分析油脂变异及其性状关联情况，采用层次分析法对优树油用性状进行综合评价。

【结果】

1）科尔沁沙地元宝枫丰产优树种仁平均含油率46.07%，变异系数为6.33%，遗传多样性指数为2.05；2）油脂中检测出14种脂肪酸成分，其中亚油酸含量（33.76%）最高，花生二烯酸的变异系数（48.32%）最大，山嵛酸的遗传多样性指数（2.08）最大；3）油脂含量在居群间及居群内的方差分量百分比分别为90.16%、9.476%，变异主要来源于居群间；14个脂肪酸含量的表型分化系数为4.484%～95.198%，其中神经酸含量表型分化系数最大，花生酸含量表型分化系数最小；4）相关性分析结果表明，油脂含量与花生一烯酸、硬脂酸含量存在极显著正相关关系（P<0.01），与神经酸呈极显著负相关（P<0.01），各脂肪酸成分间存在复杂的相关关系；5）层次分析结果显示，种仁油脂含量权重值为0.286，综合权重排名第一，脂肪酸组分中的神经酸综合权重最高（0.215），92份元宝枫优良单株的综合得分为0.320～0.611。

【结论】

科尔沁沙地元宝枫油脂性状遗传多样性丰富，具有油用种质筛选的物质基础。此外，油脂及神经酸含量在不同优树间遗传差异显著，为定向选育高含油、高神经酸含量品种提供了可能。CF-6、XA-18、XA-11、CF-11、XA-20的种仁含油率及主要脂肪酸组分含量均处于领先地位，可为元宝枫后续油用优良品种选育提供优质的种质资源。

【Objective】

To analyze the variation in oil yield and oil component composition of Acer truncatum seed kernels from Horqin sandy land, and to screen for germplasm resources with high oil value.

【Method】

This study takes seeds from 92 high-yielding mother trees collected from three provenances in Horqin sandy land as the research subjects. Oil extraction and determination, as well as fatty acid component and content determination, were performed. Variance analysis and correlation analysis were employed to investigate the variation in oil traits and the associations among different traits. The analytic hierarchy process (AHP) was used to conduct a comprehensive evaluation of the oil-related traits of superior trees.

【Result】

1) The average oil content of the seed kernels of high-yielding superior trees of A. truncatum in Horqin Sandy Land was 46.07%, with a coefficient of variation of 6.33% and a genetic diversity index of 2.05; 2) A total of 14 fatty acid components were detected in the oils, among which linoleic acid had the highest content (33.76%), arachidonic acid had the largest coefficient of variation (48.32%), and behenic acid had the highest genetic diversity index (2.08); 3) The variance component percentage of oil content among populations and within populations was 90.16% and 9.476%, respectively, indicating that the variation mainly originated from among populations. The phenotypic differentiation coefficients for the 14 fatty acid contents ranged from 4.484% to 95.198%, with the highest coefficient observed for nervonic acid and the lowest for arachidic acid; 4) Correlation analysis indicated that oil content was significantly positively correlated with the content of arachidonic acid and stearic acid (P<0.01), and significantly negatively correlated with the content of nervonic acid (P<0.01). There are also complex correlations among the different fatty acid components; 5) The results of the AHP showed that the weight value of seed kernel oil content was 0.286, ranking first in comprehensive weight; among the fatty acid compositions, nervonic acid had the highest comprehensive weight (0.215). The comprehensive scores of the 92 superior individuals of A. truncatum ranged from 0.320 to 0.611.

【Conclusion】

The genetic diversity of A. truncatum oils in Horqin sandy land is rich, providing a material basis for the screening of oil germplasm resources; Moreover, the genetic differences in oil and nervonic acid content among different superior trees are significant, which provides the possibility for the targeted breeding of varieties with high oil and high nervonic acid content; Preliminary screening identified that the seed kernel oil content and the content of major fatty acid components in CF-6, XA-18, XA-11, CF-11, and XA-20 were all at the forefront. These strains can provide high-quality germplasm resources for the subsequent breeding of oil-related superior.
