Abstract: Preharvest sprouting limits the consistent production of high quality wheat in many regions of the world. Improvements in tolerance from the introduction of better grain dormancy at, or near, harvest-ripeness would be expected to have a significant impact on the incidence and severity of sprouting. Genetic and molecular investigations have provided new evidence for the presence of dormancy genes on chromosome 3D of white-grained genotypes AUS1408 and N72.72 (T. sphaerococcumderivative), and identified a potential molecular marker for one of the dormancy genes in AUS1408. Analysis of a doubled haploid population derived from Cranbrook (extremely non-dormant, very susceptible to sprouting) × Halberd (intermediate dormancy, moderately tolerant to preharvest sprouting) identified three significant quantitative trait loci on chromosome arms 2AL, 2DL, and 4AL, all contributed by the very susceptible parent.
