Abstract

Fusarium head blight (FHB) is one of the most devastating diseases of wheat (Triticum aestivum L.), and the development of cultivars with FHB resistance is the most effective way to control the disease. Yumechikara is a Japanese hard red winter wheat cultivar that shows moderate resistance to FHB with superior bread-making quality. To identify quantitative trait loci (QTLs) for FHB resistance in Yumechikara, we evaluated doubled haploid lines derived from a cross between Yumechikara and a moderate susceptible cultivar, Kitahonami, for FHB resistance in a 5-year field trial, and we analyzed polymorphic molecular markers between the parents. Our analysis of these markers identified two FHB-resistance QTLs, one from Yumechikara and one from Kitahonami. The QTL from Yumechikara, which explained 36.4% of the phenotypic variation, was mapped on the distal region of chromosome 1BS, which is closely linked to the low-molecular-weight glutenin subunit gene Glu-B3 and the glume color gene Rg-B1. The other QTL (from Kitahonami) was mapped on chromosome 3BS, which explained 11.2% of the phenotypic variation. The close linkage between the FHB-resistance QTL on 1BS, Glu-B3 and Rg-B1 brings an additional value of simultaneous screening for both quality and FHB resistance using the glume color.

Effects of the four different combinations of QTLs for the FHB disease index in the doubled haploid lines derived from ‘Yumechikara/Kitahonami’ based on the 5-year field experiments. YK carries the resistance alleles at QTLs on 1BS and 3BS. YY carries a resistance allele at QTL-1BS. KK carries a resistance allele at QTL-3BS. KY carries none of the resistance QTLs. The lines in which all genotypes are the same between flanking markers (GluB3-barc32 for 1BS and gwm384-wmc754 for 3BS) were selected.
