Abstract
A dihaploid (DH) mapping population was developed between Tallon and Kaputar varieties and used to construct a genetic linkage map of barley. Map construction is described in an accompanying paper (Cakir et al. these proceedings). This genetic map with 195 amplified fragment length polymorphism (AFLP) and 25 simple sequence repeat (SSR) markers was used to identify markers that are linked to agronomic, disease and quality traits in barley. The population, which included 65 lines, were tested across Australia in different environments and a number of traits were measured. The marker data set and phenotypic data were used to identify quantitative trait loci (QTLs) associated with the traits. Significant associations were found for a number of traits. Notably grain yield and net blotch resistance showed significant associations on chromosomes 5H and 6H, respectively. Markers located on these regions present an opportunity for marker assisted selection (MAS) for these traits in barley breeding programs.
