“…Therefore, it is reasonable to assume that QSnl04.daw-1B and QSnl05.daw-1B are different from those previously reported on 1BS (13,16,17) based on comparative chromosomal map position for markers associated with QTL. If toxin insensitivity is associated with QTL on 1BS in this study, then a gene or genes (1,21) but the lack of common markers between genetic maps did not allow unambiguous co-location for seedling and flag leaf resistance at this locus. It was expected that QSnl04.daw-2A and QSnl05.daw-2A would reside in the same marker interval; however, analysis using data from successive years showed overlapping QTL.…”

Stagonospora nodorum blotch (SNB) is a significant disease in some wheat-growing regions of the world. Resistance in wheat to Stagonospora nodorum is complex, whereby genes for seedling, flag leaf, and glume resistance are independent. The aims of this study were to identify alternative genes for flag leaf resistance, to compare and contrast with known quantitative trait loci (QTL) for SNB resistance, and to determine the potential role of host-specific toxins for SNB QTL. Novel QTL for flag leaf resistance were identified on chromosome 2AS inherited from winter wheat parent ‘P92201D5’ and chromosome 1BS from spring wheat parent ‘EGA Blanco’. The chromosomal map position of markers associated with QTL on 1BS and 2AS indicated that they were unlikely to be associated with known host–toxin insensitivity loci. A QTL on chromosome 5BL inherited from EGA Blanco had highly significant association with markers fcp001 and fcp620 based on disease evaluation in 2007 and, therefore, is likely to be associated with Tsn1-ToxA insensitivity for flag leaf resistance. However, fcp001 and fcp620 were not associated with a QTL detected based on disease evaluation in 2008, indicating two linked QTL for flag leaf resistance with multiple genes residing on 5BL. This study identified novel QTL and their effects in controlling flag leaf SNB resistance.

“…A total of 25 (4.8 %) skewed markers (0.01 P < 0.05) were distributed on nine different LGs, ranging from zero to six for each group. Three segregation distortion regions, defined as regions with three or more closely linked markers exhibiting significant segregation distortion (Paillard et al 2003), were found on LG3, LG6 and LG7. MAT-A and MAT-B were mapped, respectively, on LG4 and LG11.…”

“…A genetic linkage map based on microsatellite (SSR) and restriction fragment length polymorphism (RFLP) markers was established (Paillard et al 2003). Three hundred and ninety four loci (186 RFLPs and 208 SSRs) were used on the 'Arina Forno' genetic linkage map, and by linkage analysis 380 of these loci mapped to 27 linkage groups with an average marker density of around 8 cM and spanning a total of 3,086 cM.…”

Stagonospora nodorum is the causal agent of the Stagonospora glume blotch disease in hexaploid wheat. The Swiss winter bread wheat cv. 'Arina' has a highly effective, durable and quantitative glume blotch resistance. We studied 240 single seed descent (SSD)-derived lines of an 'Arina x Forno' F(5:7) population to identify and map quantitative trait loci (QTLs) for glume blotch resistance under natural infestation. Using composite interval mapping (CIM) and LOD>4.5, we detected two chromosomal regions on chromosome arms 3BS and 4BL which were specifically associated with glume blotch resistance. These identified QTLs were designated QSng.sfr-3BS and QSng.sfr-4BL, respectively. QSng.sfr-3BS peaked at the locus Xgwm389 in the telomeric region of the short arm of chromosome 3B and explained 31.2% of the observed phenotypic variance for the resistance within the population. The responsible QSng.sfr-3BS allele originated from the resistant parent 'Arina'. The QTL QSng.sfr-4BL (19.1%) mapped to chromosome arm 4BL ('Forno' allele) very close to two known genes, TaMlo and a catalase ( Cat). Both QTL alleles combined could enhance the resistance level by about 50%. Additionally, they showed significant epistatic effects (4.4%). We found PCR-based microsatellite markers closely linked to QSng.sfr-3BS (gwm389) and QSng.sfr-4BL (gwm251) which make marker-assisted selection (MAS) for Stagonospora glume blotch resistance feasible. We also found one resistance QTL, QSng.sfr-5BL, on the long arm of chromosome 5B which overlapped with QTLs for plant height as well as heading time.
