Technical Abstract: This report summarizes published research across the world in 2009 that placed additional markers, genes, and quantitative trait loci (QTL) on barley chromosome 7H. An extensive single nucleotide polymorphism marker map was created and additional gene-specific markers were developed. Mapping research located genes and QTL for agronomic traits, resistance to several diseases, dormancy, preharvest sprouting and various malting quality traits. Association mapping was used to locate chromosomal regions for yield adaptability, flowering time, and height. Studies continued to examine QTLs in crosses between cultivated and wild barley with the goal of identifying new genes for barley improvement. A candidate gene for a mutation eliminating beta-glucan was identified.
