The genetic variation in the nutrient composition and anti-nutritional factors of 17 vegetable soybean genotypes were determined and a wide variation in protein %, total phosphorus (TPi) and available phosphorus (AP) was found among these genotypes. Variations in Ca, K, Fe, Mn, and Cu were also documented. Variation was also found for trypsin inhibitor (TI) activity and Phytate (PA) content. A highly significant and negative correlation (r = -0.533, P less than 0.01) was observed between TI and total protein. Strong positive correlation (r = 0.90) was also found between TPi and AP. Several genotypes (Sooty, Emperor, Wilson-5, PI 416771, PI 417322) showed good nutritional potential and can be used in the breeding program. High protein %, TPi, and minerals are desirable qualities for vegetable-type soybeans that make it as food with high nutrient density. Studies on the nutritional evaluation of immature vegetable type soybean seeds at different reproductive stages are also underway.
测定了17个菜用大豆基因型的营养成分和抗营养因子的遗传变异，发现这些基因型在蛋白质含量、总磷（TPi）和有效磷（AP）方面存在广泛差异。钙、钾、铁、锰和铜的变异也有记录。胰蛋白酶抑制剂（TI）活性和植酸（PA）含量也存在变异。TI与总蛋白之间存在极显著的负相关（r = -0.533，P < 0.01）。TPi和AP之间也发现了强正相关（r = 0.90）。几个基因型（Sooty、Emperor、Wilson-5、PI 416771、PI 417322）表现出良好的营养潜力，可用于育种计划。高蛋白含量、TPi和矿物质是菜用型大豆的理想品质，使其成为营养密度高的食物。不同生殖阶段未成熟菜用型大豆种子的营养评价研究也在进行中。
