Abstract

The introduction of semi-dwarf cereal crop varieties in the 1960s enabled extensive increases in global food production. Semi-dwarf barley cultivars have shorter stature and improved stress resistance, grain yield and quality than tall varieties. The major semi-dwarf genes, sdw1 and ari-e, have been widely used in barley breeding programmes worldwide. In this study, we identified a novel sdw1 allele in cv. Lockyer and investigated the effect of sdw1 and ari-e and their interactions on plant height, flowering time and grain yield using a Multi-parent Advanced Generation Inter-cross (MAGIC) population generated from four elite barley cultivars. Allele-specific markers combined with Kompetitive..
