摘要

Rangelands in the Qinghai -Tibetan Plateau are one of natural habitat and precious gene bank of alpine life -form in the world. Effective conservation and proper utilization of forage germplasm in the plateau is very important for alpine life -form, ecological environment and livestock production.Survey, evaluation, collection, storage and utilization of the forage germplasm have commenced since 1960's, and 2600 germplasm have been collected. One thousand three hundred and ninety three out of 2046 plant specimen collected in the plateau are forage species. Base on the collected wild and annual forage germplasm, 8 perennial grass varieties/species have been bred through domestication and selection, and 6 annual forage varieties/species have been bred. About 6.7 hectare of forage germplasm nursery has been built, where evaluation on agronomy and domestication are being carried out. Three national seed farms of pure varieties and 13333 hectare of seed production field in neighbor areas have been set up in Qinghai province. Technical specification for evaluating wild germplasm in field and data base of germplasm has been set up. Additionally, 741 oat varieties and some legume varieties have been introduced, out of which 13 oat varieties and 6 legume varieties have been selected for their adaptation to local conditions. Thirty perennial grass varieties/species have been selected from 560 introduced species.
