Sorghum Biocolor

Titre : Origin, Domestication, Diversity, and Mapping of Important Traits in Sorghum ()

Identification : 3072-21000-008-17

Pays : Etats Unis

Durée : Dec 01, 2012 à Nov 30, 2016

Objectif  : To improve our understanding sorghum origination and domestication process and as well as identify genomic regions responsible for the important agronomic traits in domesticated sorghum.

Descriptif
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.
