Abstract

A map for the barley doubled haploid population Amagi Nijo × WI2585 was constructed to examine manganese efficiency derived from Amagi Nijo. Manganese efficiency conferred by the previously identified locus Mel1 was validated. No other loci contributing to manganese efficiency were identified, possibly because of poor maker coverage in some regions. The map was additionally used to look for loci contributing to some aspects of malting quality. A locus on 2HL was found to be associated with malt extract, and 2 loci on 4HL and 5H, respectively, were found to be associated with diastatic power.

Keywords: molecular marker assisted selection, quantitative trait loci, manganese efficiency.
