Research progress of resistance of Medicago ruthenica

The research progresses of drought, cold, disease and pest resistance, and salt tolerance of Medicago ruthenica were reviewed in this study in the view of botanical characteristic, seed characteristic, phenology and growth of root and shoot, utilization value and distribution. To solve the problems in the development of M. ruthenica, this study proposed some countermeasures, including that regional adaptation, resistance genes, pod cracking, and establishment pasture, which would provide the theoretical basis for collection, preservation, development, utilization, new breeding of M. ruthenica germplasm resources and ecological restoration in the north China.
