“…Selection in early generation for resistance using AUDPC and early disease scoring to improve resistance to FHB may not be efficient, since mainly additive effects could be of practical use in durum wheat selection. Although AUDPC was often used as selection criteria for FHB resistance in winter wheat (Buerstmayr et al, 2000; Ittu et al, 2000) and in spring wheat (Bai et al, 2000), our results did not support this selection criteria because of the nature of gene action operating on the expression of this trait. Area under disease progress curve is complicated (Jiang and Ward, 2006) and time consuming particularly when a large segregating population need to be evaluated.…”

Fjusarium head blight (FHB) has recently become a major disease in durum wheat {Triticum turgiáum L. subsp. durum (Desf.) Husn. [syn. Triticum turgidum L. var. durum (Desf.) Bowden]} in Tunisia. Although partial resistance to FHB is found in durum wheat landraces, little is known about resistance genes and their effectiveness, the objective of this research was to evaluate potential resistance or tolerance to FHB using a cross between two partially resistant durum v(/heat cultivars. Divide, a North Dakota State University (NDSU) cuitivar, and Tun7, a Tunisian landrace. Seven populations (P^, P^, F^, Fj, F3, BC,, and BCg) were evaluated in the greenhouse. Percentages of infected spikelets (PIS) Were evaluated at 7,14, and 21 d postinoculation (DPI) and area under disease progress curve (AUDPC) and Fusarium-damaged kernels (FDK) Were measured. Mean generations analysis indicated that dominance effect (h) and dominance X dominance epistasis effect (/) contributed largely to the expression of partial resistance to HHB as measured by the PIS observed at 7 DPI (k = -8.9 and / = 10.4), 14 DPI (h = -28 and / = 3;3.7), and AUDPC (h = -300.5 and / = 340). Variance components indicated that additive effect (d) and additive x additive epistasis effect (/) are FJredominant components in the disease development at 21 DPI (d = 8.5 and / = -9). Additive ejffect (d) appeared to condition the expression qf FDK (d = -3). Heritability estimates were 0.42 for PIS observed at 21 DPI and 0.84 for FDK. These results suggest that disease scoring at 21 DPI and FDK could be used to screen for FHB in early generations.

“…Several other resistance QTL have been mapped to chromosome 1B, of which some have mapped within the 1BL.1RS translocation. The lines with resistance QTL within or close to the translocation included the British cultivar Lynx (Schmolke et al, 2005), the Dutch cultivar Romanus (Holzapfel et al, 2008), the CIMMYT cultivar Seri82 (Mardi et al, 2006), and the Romanian cultivars Sincron (Ittu et al, 2000) and Fundulea201R (Shen et al, 2003). The Chinese cultivar Wangshuibai also contained a QTL on chromosome 1BS (Zhang et al, 2004).…”

Fusarium head blight (FHB), primarily caused by Fusarium graminearum, can significantly reduce the grain quality of wheat (Triticum aestivum L.) due to mycotoxin contamination. The objective of this study was to identify quantitative trait loci (QTL) for FHB resistance in the moderately resistant soft red winter wheat cultivar NC‐Neuse. A total of 170 recombinant inbred lines (RILs) from a cross between NC‐Neuse and the susceptible cultivar AGS 2000 were evaluated in inoculated, mist‐irrigated field nurseries. The lines were evaluated for FHB incidence (INC), severity (SEV), Fusarium‐damaged kernels (FDK), and deoxynivalenol (DON) content in seven environments between 2011 and 2014. A 3,419 cM linkage map was developed based on 1839 simple sequence repeat (SSR), diversity array technology (DArT), and single nucleotide polymorphism (SNP) markers. Seven FHB resistance QTL on chromosomes 1A, 1B, 1D, 2A, 4A, 5B, and 6A were mapped. The QTL alleles conferring resistance on 1A, 1B, 2A, 4A, and 6A originated from NC‐Neuse, while the alleles associated with resistance on 1D and 5B originated from AGS 2000. Quantitative trait loci effects ranged from 9 to 12% for INC, from 6 to 11% for SEV, from 8 to 20% for FDK, and from 6 to 18% for DON. The QTL on 5B co‐localized with the Vrn‐B1 locus. Kompetitive Allele‐Specific PCR (KASP) assays were developed for each NC‐Neuse QTL region. A preliminary test using these assays on recent Uniform Southern Winter Wheat Nursery (USWWN) entries indicated Qfhb.nc‐1A, Qfhb.nc‐1B, and Qfhb.nc‐6A as likely the best candidates for use in marker‐assisted selection.

“…1), indicating that both parents carry positive and negative alleles, as has been reported in other studies (e.g., Buerstmayr et al, 1999; Waldron et al, 1999; Miedaner et al, 2003; Liu et al, 2005). Transgressive segregation has been observed in wheat for head blight rating when medium to highly susceptible parents are crossed (Snijders, 1990; Singh et al, 1995; Buerstmayr et al, 1999; Ittu et al, 2000). The transgressive segregation observed toward lower values for FHB and DON content suggest that both parents contributed favorable alleles to their offspring; thereby creating an opportunity to identify superior gene combinations in the population by selection.…”

Quantitative Trait Loci Controlling Fusarium Head Blight Resistance and Low Deoxynivalenol Content in Hexaploid Wheat Population from ‘Arina’ and NK93604

Breeding for Fusarium head blight (FHB) resistant wheat adapted to the Norwegian climatic conditions is one of the top priorities in the country. This study was conducted to characterize QTLs for FHB resistance and low deoxynivalenol (DON) content in a population of 93 double haploid lines from a cross between ‘Arina’ and NK93604. Both parents have moderate levels of resistance to FHB. The population was assessed for FHB resistance under field conditions for 3 yr (2001 to 2003), and DON content was analyzed from seed samples in the 2002 experiment. The two traits showed significant genetic variation and were significantly correlated with each other. Composite interval mapping (CIM) identified four QTLs using the 3 yr mean for FHB resistance on chromosomes 1AL, 1BL, 6BS, and 7AL. The QTLs on 1AL, 1BL, and 7AL were consistently detected in all 3 yr, and explained 27.9, 19.6, and 14.8% of the phenotypic variation, respectively. The QTLs on chromosomes 1BL and 6BS originated from Arina, whereas those on 1AL and 7AL were from NK93604. None of the QTLs for FHB resistance detected in this study were coincident with those previously reported in the Arina/‘Forno’ population. Two major QTLs, both derived from NK93604, on chromosomes 1AL and 2AS were identified for DON content that explained 27.9 and 26.7% of the variation, respectively. A major QTL for FHB resistance on 1AL coincided with a QTL for DON content. As far as we are aware, the QTL on chromosome 1AL is novel and not reported elsewhere. Data from the present study provides breeders with additional information on chromosomal regions associated with FHB resistance and DON content in European wheats and will help guide the development of FHB‐resistant wheat.
