Track 4-1-1: Plant Genetic Resources, Collection, Conversation, Evaluation and IPR Issues
Description
Sorghum (Sorghum bicolor) and sudangrass (S. sudanense) are two members of the agriculturally important genus Sorghum. Hybrids of these two species have exhibited favorable forage yields and overall improved quality and disease resistance (Zhan and Qian, 2004). Sorghum–sudangrass hybrids (Sorghum bicolor × S. sudanense) are used as a forage crop and recommended as an alternative to corn in USA (Kilcer et al., 2003). In recent years, the planting areas of sorghum–sudangrass hybrids have increased in China. SSR has been widely employed in crop germplasm identification, genetic mapping and diversity analysis (Zhan et al., 2008, Li et al., 2010). However, no reports have been published on studies of the genetic diversity of main sorghum–sudangrass hybrids in China. The objective of this current study was to evaluate the genetic diversity and relationship among 19 accessions of sorghum-sudangrass hybrids as revealed by SSR markers.
