【Abstract】 Medicaogo sativa cv.Yumu No.1 was selected from introduced varieties by bulk-population selection. The results showed that this variety produced high dry matter yield and had hot-humid tolerance, erect, root branching and other characteristics. The average annual dry matter yield of 15.0 t/hm2was produced, and 22.4% crude protein content of whole plant flowering period, crude fiber content of 23.1%, 2.3% crude fat, and 7.7% crude ash content were detected. Yumu No.1 can be used for forage, hay production, and suitable for planting in humid areas in southwest of China.更多还原
