Breeding sustainable forages for Alpine areas in Qinghai Province
The fencing of degraded rangelands, the desertification,erosion and salinisation of soils and the expansion of other agricultural restrictions resulted in the increase of grazing pressure in the highlands of Qinghai where average altitude,is 4000m (Luo 2001 ).However, there is a great potential for increasing livestock production by planting improved forages and distributing animals wisely in existing rangelands ( National Research Council 1992 ).Seeds produced from.Qinghai bred varieties of Elymus gradually lost persistency under grazing (Zhou 2006).This might be inherent to the species but also to the selection for seed yield.The natural germplasms were used to breed new varieties adapted to heavy and temporary grazing in the highlands of Qinghai this breeding program.
