Investigation and collection of wild forage germplasm resource in Jilin Province

In order to provide information on the conservation, research and development of wild forage germplasm resources, a total of 191 germplasm resources of valuable wild forages were collected during 2008－2009 in Jilin Province. The results of this study showed that the 191 germplasm resources covered 18 families, 59 genera, 89 species, of which 91 were Leguminosae, 64 were Gramineae and 36 were other sections. In these wild forage germplasm samples there were not only unique local wild species and a number of adaptable, widely distributed, variations in species, but also wild species and wild relative species of excellent cultivated grasses in different habitats. Distribution of some key genera and species，and their relationships with habitat condition were also summarized. This study provided abundant wild forage germplasm resources for screening and cultivation of new varieties of grasses, and important scientific information on wild grass germplasm resource conservation, development and utilization.
