2002年我国大豆(Glycine max)品种及种质资源的蛋白质和脂肪含量分析

对2002年全国14个主要大豆种植省(区)的大豆品种及其种质资源的蛋白质、脂肪含量进行了分析。结果表明，种质资源的蛋白质、脂肪平均含量均高于生产用品种。其中种质资源脂肪含量的变化幅度较大，显示了在未来的育种中更强的高脂肪含量的选择优势。国内种质资源蛋白质平均含量高于国外种质资源。国外种质资源脂肪含量总体上高于国内种质资源。黄淮海生态区品种蛋白质平均含量高于北方生态区品种。新育成黄淮海区域试验品种蛋白质平均含量高于目前黄淮海生态区生产用品种。同品种异地种植，其脂肪含量有明显变化。

Investigation on Quality Characters of Soybean (Glycine max ) Varieties and Germplasm Grown in 2002

Soybean(Glycine max)production varieties and germplasm from 14 Chinese major planting provinces in the year of 2002 have been investigated with regard to protein and fat contents . The investigation showed that the average protein and fat content of soybean germplasm appeared to be higher than those of the varieties used in production ,respectively. The range of fat content of germplasm was so broad as to exhibit superior selective advantage in soybean breeding for higher fat contents. The average protein content of the domestic soybean germplasm was higher than that of germplasm introduced from abroad, and the average fat content of germplasm from abroad was higher than the domestic germplasm .The average protein content of the soybean varieties from the Huanghuaihai ecological region seemed to be higher than that of varieties from the northern ecological region.However, the average protein content of soybean varieties used in production from the Huanghuaihai ecological region at present proved to be lower than that of newly bred testing varieties in the same region .The same varieties planted in different locations varied greatly in respect of fat contents.
