SEED PROTEIN ELECTROPHORESIS PROFILES OF WILD SOYBEAN (G. SOJA) IN CHINA : THE FREQUENCIES AND GEOGRAPHICAL DISTRIBUTION OF Ti AND Spl ALLELES AND THE HYPOTHESIS ON THE ORIGINAL AREA OF SOYBEAN

Xu Bao, Zhao Shu-wen, Zou Shu-hua, Zhen Hui-yu (Soybean Institute, Gongzhuling, Jilin, China)Hu Ziang, Wang Hong-Xin (Institute of Botany, Academia Sinica, Beijing, China) The frequencies oi' Ti and Spl alleles of seed protein of 339 wild soybean (G. soja) accessions in China were calculated on the basis of protein electr ophoresis analysis. About 80% of the accessions had the Tia allele and only one was identified as having the Tic allele. About 47% of the accessions had the Spia allele and only one had neither Spla nor Splb. According to the geographical distribution of Tia allele frequencies, 8 regions were divided in China. Judging from the difference of Tia% distribution between wild and cultivated soybean, it was supposed thai North China might be the main origonal area of soybean.
