Introduction, selection and application of high quality forages in Guizhou

It is very important to select and breed local high quality forages and application for ecological animal husbandry development and rocky desertification control in Guizhou. The achievements in the last 30 years were summarized in this paper. The result indicated that over 10 forage species (including 100 germplasm materials) were introduced. Over 1000 local wild germplasms were collected and identified. In the last 15 years, 9 new forage varieties were bred through introduction, domestication and screening, and these had made a certain contribution to the promotion of animal husbandry in Guizhou. The main problems and future research work were discussed as well.
