Fusarium head blight (FHB) is a devastating disease of wheat in Canada, causing severe losses in grain yield and quality. The most effective way to control the disease is to use resistant wheat cultivars. FHB resistance is a quantitatively inherited trait controlled by multiple genes. Strong genotype-by-environment interactions affect phenotypic evaluation and genetic analysis of FHB resistance. Quantitative trait loci (QTLs) analysis can allow the identification of genomic regions associated with resistance, and the markers linked to those regions can be used in marker-assisted selection without concerning environmental effects. The wheat accession PI 277012 has a high level of resistance to FHB. The resistance was derived from T.timopheevi based on pedigree. Two major quantitative trait loci (QTLs) for FHB resistance have been identified on chromosome arms 5AS and 5AL in a population of 130 DH lines derived from the cross PI 277012/’Grandin’. Another wheat line, HC 374, also has good FHB resistance that is derived from a Chinese wheat line ‘Wuhan and a Japanese wheat cultivar ‘Nyubai’. QTLs analyses indicate that genes for resistance to FHB are located on chromosomes 2DL, 3BS, 4B and 5AS. SSR markers that are closely linked to FHB resistant genes in wheat lines PI 277012 and HC374 are available. The objective of this study is to pyramid these resistant genes into a Canadian wheat genotype through a combination of modern doubled haploid breeding techniques and molecular marker assisted selection.

C – Proposal Description/ Description de la proposition
Objective/Objectif :
Stem rust race TTKSK (Ug99) and its variants are migrating from East Africa and threatening wheat production worldwide. An efficient way to control stem rust is by using resistant wheat cultivars containing a pyramid of genes. The Canadian wheat cultivars ‘AC Cadillac’ and ‘Peace’ are highly resistant to Ug99. These cultivars share the common bunt resistant line ‘BW553’ in their pedigrees. Ug99 resistance of these cultivars have been investigated and the results indicate that the two cultivars have the same resistant gene, named SrCad = Sr42. This gene is mapped on the short arm of chromosome 6D and the molecular marker FSD_RSA is tightly linked to SrCad gene with 1.6 cM. The Australian wheat cultivar ‘Lang’ has stem rust resistant gene Sr36. This resistant gene is derived from T. timopheevii and located on the short arm of chromosome 2D. Recently, three markers, Xstm773-2, Xgwm319 and Xwmc477, are identified to be closely linked to Sr36. The objectives of this study are to introduce Sr36 into Canadian wheat ‘Hoffman’ and pyramid Sr36 with SrCad in a Canadian wheat background by means of marker assisted selection.
