The present situation and prospect of tropical and subtropical forage germplasm resources investigation,collection, conservation and utilization in South China

摘要

As a preliminary agricultural natural resource, forage plays an important role in the grassland livestock industry, ecological environment, and the sustainable development of agriculture. This paper summarizes the survey, collection, conservation and identification of tropical and subtropical forage genetic resources, as well as the methods of collection,reproduction and conservation in South China. Tropical Pasture Research Center (TPRC) of CATAS has been engaged in research of the tropical and subtropical forage resources collection, conservation and utilization from 1940s. Now a copy gene bank in low temperature, 1 plant library in vitro and 1 nursery station in plant plantation have been established. In total, 5190 indigenous fodder shares belonging to 435 species, 161 genera, 12 Families have been surveyed and collected in South China;1042 exotic shares belonging to 87 species, 42 genera with grass and legume have been introduced and conserved;2870 shares belonging to 207 species, 96 genera, 6 families have been conserved in seed copy bank;482 shares belonging to 6 species, 6 genera, 3 families in vitro;and 341 shares belonging to 10 species, 8 genera, 3 families in the nursery in plant preservation.
