Abstract

In crop plants, the potential of association mapping, with the objective of estimating the position of genes conferring a specific trait or phenotype using linkage disequilibrium (LD) between alleles of genetically mapped markers, has recently become a focus of considerable interest. One major attraction of association genetics is the potential to locate genes responsible for a wide range of traits in a single sample population using pre-existing phenotypic data that has been collected during crop improvement and cultivar registration programs. This study testify to the potential of exploiting whole genome LD-scans to locate genes controlling key biological traits in cultivated barley. We are currently increasing the density of markers, particularly those with a MAF >0.1, by developing two further pilot OPAs, which in due course will be compressed into two commercially available platforms for high throughput low cost genotyping in cultivated barley. In the immediate future these will be used in large association genetic studies in the UK and US involving approximately 4000 barley genotypes with the aim of realising the potential for whole genome association genetic scans in cultivated barley.
