以非转基因大豆受体东农47为对照,对前期已获得的转SiDGAT1的4个大豆株系种子含油量、脂肪酸含量、蛋白质含量及植株主要农艺性状等进行鉴定。结果表明,与非转基因对照相比,转SiDGAT1大豆种子的含油量提高,蛋白质含量降低,但各脂肪酸组分没有显著改变。除S-1株系外,其他3个株系的植株农艺性状与对照相比均无显著改变。 The non-GMO soybean cultivar Dongnong 47 was used as a control to identify the oil content, fatty acid content, protein content and plant agronomic traits of the four soybean lines which had been obtained previously. The results showed that compared with the non-transgenic control, the oil content of transgenic SiDGAT1 soybean seeds increased, but the protein content decreased, but the fatty acid components did not change significantly. Except S-1, the agronomic traits of the other three lines showed no significant change compared with the control.
