Abstract: In this study we built two sub-population from the LD base population which fit for our ecology type by 6 years’ gene enrichment and recurrent selection. For the db(high protein content) sub-population, the protein content is 1.18% higher than the base population, and the individuals which protein content more than 45% are 22.38%, 10.99% higher than the base population; For the gy(high oil content) sub-population, oil content is 0.24% higher than the base population, and the individuals which oil content more than 20% are 11.05% higher than the base population. In addition, compare the two ms1 sub-population with the segregation population of general crosses on the type of flower date, mature date, pod type, hilum color and hair color etc , the former have wider separation, and has more types. On the other hand, we also discussed the breeding method, key technology and selection effect of soybean Ms1 population.
