Wheat (Triticum aestivum L.) grain hardness is controlled by the Hardness locus on chromosome 5D which consists of the linked genes Puroindoline a and b (Pina and Pinb, respectively). The Ha locus haplotype, Pina-D1a/Pinb-D1a is found in all soft hexaploid wheats. While Pin diversity is low among soft wheats, several novel Ha haplotypes were reported among synthetic hexaploid wheats created using the D genome donor. Aegilops tauschii. One haplotype, Pina-D1c/Pinb-D1h, confers a soft phenotype with increased grain hardness over Pina-D1a/Pinb-D1a wheats. Here, the Pina-D1c/Pinb-D1h haplotype was backcrossed into the soft white spring wheat cultivars 'Vanna' and 'Alpowa'. Then the effect of the two haplotypes on soft wheat in and baking quality was compared. The effects of the Pina-D1c/Pinb-D1h Ha locus haplotype were similar in both the Vanna and Alpowa backgrounds. The Pina-D1c/Pinb-D1h lines had significantly more large and fewer small flour particles in both backgrounds and 1.51% higher flour yield in the Alpowa background. The Pina-D1c/Pinb-D1h haplotype group was not associated with any consistent differences in solvent retention capacities or sugar snap cookie. quality parameters. The results indicate that the Pina-D1c/Pinb-D1h haplotype could he used to modify soft wheat milling properties without substantial effects on baking quality.
