Objectives are for the identification of genetic variability for nutritional traits in common bean, the discovery of the genes or quantitative trait loci (QTL) controlling that variability and the development of DNA markers that can be used by plant breeders to incorporate QTL into new and more nutritional common bean cultivars.
Single Nucleotide Polymorphism (SNP) DNA markers will be discovered via the use of high throughput DNA sequence analysis using the Illumina/Solexa Genome Analyzer as well as via the analysis of common bean DNA gene fragments amplified using polymerase chain reaction (PCR) primers designed to orthologous soybean genes. Because common bean market classes fall into three distinct groups based on their geographic origins in Central or S. America, three sets of 768 SNP panels specific to the three groups will be developed. These three sets of SNPs will be used to characterize common bean populations segregating for nutritional traits for purposes of QTL discovery. The SNP analysis will be conducted using the Illumina GoldenGate assay which is analyzed on the Illumina BeadStation.
