通过分析１９２份山东省小豆品种资源籽粒的蛋白质含量及与品种生育特性的关系表明，品种间的蛋白质含量变异幅度较大，且来源于不同地区的品种间也有较明显的差异，以胶东地区的品种的蛋白质含量较高，变异系数最大；红小豆和绿小豆品种蛋白质含量较高；蛋白质含量与品种的百粒重呈极显著的正相关，生育期长的品种其籽粒的蛋白质含量较高。 By analyzing the relationship between the protein content of 192 accessions and their reproductive characteristics, it was found that the variation of protein content among cultivars was large, and there were also significant differences among the cultivars derived from different regions. The protein content of varieties was higher and the variation coefficient was the highest. The protein content of red adzuki bean and adzuki bean was higher. The content of protein had a very significant positive correlation with the hundred kernel weight of the varieties, and the protein content of the grains with longer growth period was higher.
