Collection, Conservation and Innovative Utilization of Tropical Forage Germplasm Resources
Plenty of accessions of tropical forage germplasm have been collected and conserved in recent 20 years due to the continuous support of the State Program initiated in China. A collection and conservation system has been established, the major components of which include the South China Coordination Team, Tropical Forage Germplasm Duplication Gene Bank (Hainan) , and the Ministry of Agriculture Danzhou Germplasm Repository of Tropical Forages. More than 5400 accessions of tropical forage germplasm have been collected recendy, of which over 5000 accessions have been conserved. Of all the accessions conserved 4530 are conserved in the Tropical Forage Germplasm Duplication Gene Bank, including 499 species (421 wild species with 3799 accessions, 79 exotic species introduced from overseas with 731 accessions), 174 genera and 9 families, and 1200 are conserved in vivo in the Ministry of Agriculture Danzhou Germplasm Repository of Tropical Forages. Innovative development and utilization of these forage germplasm conserved have been initiated actively, and 83 new tropical forage varieties suitable for spread in the tropical and subtropical areas in China had been selected, passed expert examination of the National Herbage Varieties Examination Committee, and registered till 2008.
