摘　　要：[目的]比较高寒地区引种栽培的12个桑树优良品种抗寒性、丰产性。[方法]比较引进栽培的12个桑树优良品种的枯梢率、抗寒指数以及各品种间单株产叶片数、单株叶产量等指标。[结果]高寒地区引种栽培桑树品种间抗寒性、丰产性差异较大。[结论]该研究为高寒地区桑叶产业发展提供了理论依据。[Objective] An experiment was done to measure and compare the cold resistance and high yield of 12 Mulberry varieties intro- duced from alpine area. [ Method] Dieback rate and cold resistance index were compared between introduced 12 Mulberry varieties and local small leaves of Mulberry; leaf number per plant among the varieties and leaf yield per plant were compared. [ Result] The difference in cold resistance and high yield of these Mulberry varieties introduced from alpine area is quite big. [ Conclusion] A theoretical basis was provided for the development of Mulberry industry in alpine region.
