Abstract
The discovery and use of DNA markers has heralded a new era in providing necessary tools for marker-assisted selection (MAS). Simple sequence repeats and recent single nucleotide polymorphism markers, available all over the genome, have become markers of choice for gene/quantitative trait loci (QTL) mapping and for MAS/marker-assisted breeding (MAB). Sequencing of sorghum whole genome and its availability on public domain has accelerated the pace of these activities, and candidate gene markers are being developed rapidly for various traits. The prospective targets of MAS include economically important traits such as grain yield and other agronomic traits, quality traits, and resistances to abiotic and biotic stresses. Over the past decades, substantial progress has been achieved in the development of genomic resources in sorghum. QTL mapping of agronomic, biotic, and abiotic stress traits has resulted in identification of many QTL spread across the genome. Validation and fine mapping of QTL provide an opportunity to employ MAS for sorghum improvement.
