本试验以２５个大豆品系为材料，在东北三省８个地点同时进行试验，目的是研究生态环境对大豆脂肪酸含量的影响。结果表明，亚麻酸、亚油酸及棕榈酸表现出北高南低的变化趋势；油酸与之相反，北低南高；硬脂酸变化趋势不明显。５种脂肪酸都存在极显著品系×环境工作。各脂肪酸性状的地点变异系数与品系的变异系数都很接近，说明在此范围内生态环境对各脂肪酸表现型的影响基本上与品系间的遗传差异接近。各脂肪酸性状的地点相关分析表明，品系脂肪酸含量的相对表现在各环境下是基本相近的，虽然环境条件影响大豆的主要脂肪酸含量，但是其对脂肪酸含量的顺位影响不大，在一个地点高往往在其他地点也高，体现了品系遗传性的存在。同时也表明，在异地对适应当地品系的脂肪酸含量的选择也是有效的。
In this experiment, 25 soybean strains were used as materials and tested simultaneously in 8 locations in three provinces of Northeast China to study the effects of ecological environment on the fatty acid content of soybean. The results showed that linolenic acid, linoleic acid and palmitic acid showed the trend of north high and low south; oleic acid was the contrary, the north and the south were high; and the change tendency of stearic acid was not obvious. Five kinds of fatty acids exist extremely significant line × environment work. The coefficient of variation of each fatty acid trait is very close to the coefficient of variation of the strains, indicating that the influence of the ecological environment on each fatty acid phenotype in this range is basically similar to the genetic differences among the strains. The correlation analysis of the fatty acid traits showed that the relative performance of the fatty acid content of the strains was basically similar in all environments. Although the environmental conditions affected the main fatty acid content of the soybean, it had little effect on the cis-position of the fatty acid content. Often in other locations are also high, reflecting the presence of genetic lineage. It also shows that the choice of fatty acid content suitable for local lines is also valid at different locations.
