Abstract: [Objective] To screen alfalfa varieties with higher nutritional value in Hinggan League, Inner Mongolia. [Method] Using 34 foreign alfalfa varieties as experimental materials, planting studies were carried out at Hinggan League, Inner Mongolia. The contents of crude protein, crude fat, crude ash, neutral detergent fiber and acid detergent fiber of the 34 varieties were measured.The relative feeding value were calculated, and the nutritional value was comprehensively evaluated by membership function method.[Result] Among the 34 alfalfa varieties tested, the highest contents of crude protein, crude fat, crude ash, neutral detergent fiber and acid detergent fiber were 'SK3010', 'Algonquin', 'Kangsai' and 'Challenger' respectively. 'Juneng 2' had the highest relative feeding value. The varieties with a superior overall evaluation using the membership function approach were 'Juneng 2', 'SK3010' and 'Algonquin'. [Conclusion] Among the 34 alfalfa varieties evaluated, 'Juneng 2', 'SK3010' and 'Algonquin' had higher promotion and utilization value in the cold and dry area of Hinggan League, Inner Mongolia.
