520 |a Improvement of preharvest sprouting (PHS) resistance is an important objective in the breeding of durum wheat (Triticum turgidum ssp. durum (Desf.) Husn.) in Japan, where the harvest timing overlaps with the rainy season. In a previous study, we showed that an R-gene associated with red seed color was the most effective at promoting PHS resistance in durum wheat. However, red-seeded durum wheat is not popular because it discolors pasta. Here, to improve PHS resistance without the R-gene, we introduced a PHS resistance allele of MOTHER OF FT AND TFL 1 (MFT) and a mutated ABA 8'-hydroxylase (ABA8'OH1-A), which is involved in abscisic acid (ABA) catabolism, singly or together into white-seeded durum wheat. The introduction of both genes reliably and stably improved PHS resistance under all tested conditions. Modification of ABA catabolism might be an effective way to improve PHS resistance in durum wheat. Our findings will contribute to improved PHS resistance in breeding for white-seeded durum wheat
