摘要
我国１．９万份大豆（栽、野）种质资源的胰蛋白酶抑制剂（ＳＢＴＩ）等位基因电泳分析结果指出，９８．２％的材料具有Ｔ型，１．３％的材料具有Ｔ型。在野生材料中发现有Ｔ类型。三种基因型出现的频率比例为１００：１．３：０．２。未发现不含胰蛋白酶抑制剂的ｔｉ型材料．栽培种Ｔｉ类型单一，野生种Ｔｉ类型变异较大。
About 19. 000 accessions of soybean sermplasm have been analysed by polyacrylamide gel elect rophoresis for soybean trypsin inhibitor (Ti). The results showed that 98.2% of the soybean varities had T alleies. 1. 3% had T alleies .and they were found in the sermplasm accessions from north China. T was found in wild accessions from south China.The frequency of T,T and T was 100: 1. 3: 0. 2. No genotype without trypsin inhibitor (ti)was found. The T alleles in the cultivated varieties were similar while those in the wild soybean species had a rather vast variation.
