Completing genotyping of composite germplasm set of sorghum

This project was designed to establish a composite germplasm set of circa 3000 accessions of wild and cultivated sorghum, determine the population structure of this using approximately 50 SSR marker loci distributed across all 10 linkage groups of the genome of cultivated Sorghum bicolor, and based on this information develop a reference germplasm set of sorghum for use in allele mining and linkage disequilibrium mapping. This was completed in 2007. Due to difficulties in getting the required genome coverage with publicly available SSR markers, additional markers were developed and an additional set of 40 of these have been used in 2008 to validate the population structure of the sorghum reference germplasm set
