大豆是粮油兼用作物,是人民生活需要的蛋白质和脂肪的重要来源。因此,大豆含蛋白质和脂肪的多少,是衡量其品质好坏的重要标志。为了充分利用大豆品种资源,以选育出高蛋白质和高脂肪的大豆新品种,我们对湖北省大豆品种资源376份进行了脂肪含量的测定,其中194份测定了蛋白质含量。测定方法,蛋白质含量用半微量凯氏定氮法,全氮量乘系数6.25得蛋白质含量,相对误差小于2％,脂肪含量用索氏提取法(残 Soybean is a staple food and oil crop and is an important source of protein and fat needed by people’s lives. Therefore, the amount of soy protein and fat, is an important indicator of its quality is good or bad. In order to make full use of soybean resources to breed new high-protein and high-fat soybean varieties, we measured the fat content of 376 soybean germplasm resources in Hubei Province, of which 194 were used to determine the protein content. Determination of protein content using semi-micro Kjeldahl method, the total nitrogen multiplied by a factor of 6.25 protein content, the relative error of less than 2%, fat content by Soxhlet extraction method (residual
