摘要
The geographical distribution of maturity groups classified with international standard for summer planting types was analysed for main distribution regions.It was shown for each maturity group that there are one or two regions in which soybeans were distributed more densely than in other regions. The knowledge of geographical distribution of the maturity groups of soybean in China could help to study seed exchanges among different eco-regions in China and among different countries in the world.
