Abstract
wild soybean materials have been collected, arranged and identified during 1979 to 2003. 676 crosses have been made between different species. Some outstanding wild soybean natural resources have been selected including 49 with protein content over 480mg·g-1, 8 with resistant to race 3 of SCN, 5 with resistant to soybean mosaic virus, 9 with multi-pods and branches and against adverse circumstances. Longpin 8807 and other 8 sources of soybean which content both high protein and oil(661.6mg·g-1)were selected. Also some middle materials were selected induding high protein content, hundred grain weight between 6-20g, against adverse circumstances and high yield potential. New variety Long xiaolidou No 1 has become main source of export income. Cultivars Heisheng 101 bred by pollen tube pathway have broaden soybean germplasm, improved spring soybean gene pool.
