以来自湖北、广东等地区58份具有代表性的地方大豆种质资源为研究材料,测定了各品种的蛋白质含量、脂肪含量和含水量,计算了蛋脂总量,并进行了统计学分析。结果表明:58份大豆种质资源中蛋白质含量最大值为51.19%,最小值为40.68%,变异系数为12.57%;其脂肪含量最大值为19.87%,最小值为13.31%,变异系数为15.85%;而蛋脂总量的最大值为66.77%,最小值为56.84%,变异系数为9.05%。通过筛选比较后,最终选出16份可作为优质资源,其中来自湖北潜江的大豆MD216可作为蛋白专用品种。

In this study,58 representative local soybean germplasm resources from Hubei,Guangdong,and other regions were used as research materials. Through field experiments and testing,the protein content,fat content,water content,and total protein-fat content of each variety were determined,and statistical analysis was carried out. The results showed that the maximum protein content in 58 soybean germplasm resources was 51. 19%,the minimum was 40. 68%, and the variation coefficient was 12. 57%; the maximum fat content was 19. 87%, the minimum was 13. 31%, and the variation coefficient was15. 85%; the maximum total protein-fat content was 66. 77%, the minimum was56. 84%,and the variation coefficient was 9. 05%. After screening and comparison,16 of58 soybean accessions were finally selected as excellent resources. Among them,MD216 from Qianjiang,Hubei,can be used as a special protein variety.
