摘　　要：1987～1989年,用聚丙烯酰胺凝胶电泳技术检测了东北三省的2277份栽培大豆种子蛋白中胰蛋白酶抑制剂(Ti)和β—淀粉酶(SP_1)位点的等位基因型。检测结果:Ti位点,Ti^a型共2267份,占总检测品种数的99.56％,Ti^b8份,占0.35％,Ti^c2份,占0.09％,未发现ti型。SP_1位点,SP_1~b2141份,占94.03％,SP_1~a110份,占4.83％,SP_1^(an)12份,占0.53％,SP_114份,占0.61％。Two seed proteins, trypsin inhibitor (Ti)and β-amylase (SP1),from 2277 accessions of soybean germplasm from three provinces of Northeast of China were analyzed by polyacrylamide gel electrophesis. For Ti locus, 2267 accessions had the Tia allele, 8 Tib, and 2 Tic, accounting for 99. 56% , 0. 35% and 0. 09% of the total tested, respectively. No ti type was found. For SP1 locus, 2141 soybeans had the SP 1b,111 SP 1a,12 SP 1an and 14 SP1 allele, accounting for 94. 03% , 4.83%, 0. 53% and 0. 61 % of the total accessions respectively. The geographic distribution of the alleles in the Ti and SP1 loci was examed. The results would be useful in the application of the soybean germplasm resource and in the exploration to the problem of soybean ori-gin and dissemination.
