For this study, different landrace accessions and various representative breeding lines and cultivars will be collected from diverse geographic locations worldwide. This collection of sorghum accessions/lines will be genotyped through direct resequencing, and then single nucleotide polymorphism (SNP) will be identified throughout chromosomes in this diverse set of wild and cultivated sorghum accessions. The evolutionary history of domesticated sorghum will be assessed by a diffusion-based approach, and the genetic variations and relationships among these representative sorghum collection will be determined based on molecular evidences obtained from this study and previously published databases. Finally, genomic regions and/or molecular markers responsible for the variation in the important agronomic traits will be interpreted association mapping technology.
