Genetic Mapping of Valuable Traits in Barley

These researchers are investigating the genetics of numerous traits in barley. Much of this work involves construction of genetic linkage maps with molecular markers using experimental mapping populations. The group is also developing new genetic markers for mapping. PCR primers for simple sequence repeat markers are designed from DNA sequence information from barley expressed sequence tag libraries. These new markers are designed to fill in gaps and improve overall coverage of the barley genetic map. Current quantitative trait locus mapping studies focus on disease-resistance genes, genes that contribute to yield and agronomic performance, and genes that are involved in malting quality. Another area of interest for these researchers is the use of mixed models to detect marker-trait associations using breeding germplasm.
