“…The heterosis effect detection is a significant finding in the case of characteristics associated with resistance to Fusarium head blight. Similar conclusions were derived also by other studies, when it was found out that even where parental material is moderately susceptible, anecdotal evidence suggests that transgressive segregation may be an important factor in FHB-resistance breeding as evidenced by three widely used varieties, Ernie, Sumai3, and Truman, each of which was derived from moderately susceptible parents (McKendry et al 1995(McKendry et al , 2005Bai et al 2000). In that study it was evidenced that the low content of DON can be achieved even after the cross process of the susceptible variety with a moderately resistant variety (Cubus/Bakfis).…”

The aims of the present study were to estimate the general combining ability (GCA) and the specific combining ability (SCA) effects controlling type II FHB resistance across environments in a set of European winter wheat varieties and, for purposes of future selection, to identify potential combinations of parents with suitable levels of FHB resistance. Parental varieties as well as F 1 generations were evaluated under both field and greenhouse conditions in two years. The results of the present study indicate that in the F 1 generation mean DON content was relatively lowest after crossing of moderately resistant parents (Sakura/Bakfis, Sakura/Federer, Petrus/Bakfis, and Sakura/Petrus), and mean DON content is low also after crossing the moderately resistant Bakfis variety with the susceptible Biscay and Cubus varieties. Evaluation of crosses in the F 1 generation was followed by evaluation of selected crosses (derived from the Bakfis and Sakura varieties) in the F 2 generation. Correlations between F 1 and F 2 were highly significant in relation both to their DON content and visual symptom score (VSS), as well as between the individual experiments (and in the different years). The only exception was in the case of the 2014 field experiment, when inoculation was successful but conditions were not optimal for the disease to progress and DON to accumulate. The selection of a suitable parental variety (with a high GCA) can markedly influence the success rate of breeding for resistance to FHB. Detection of high SCA in the F 1 generation is important for directing breeders to promising combinations for achieving FHB resistance. It was demonstrated here that low DON content may be achieved even after crossing a moderately resistant variety with susceptible varieties. Another possibility is to make use of heterosis directly for acquiring resistance in hybrid wheat (for decreasing DON content and manifestation of symptoms).

“…After more than a decade of FHB research on plant introductions, wheat breeders in the SRW wheat region of the US consider the use of FHB resistance from locally adapted sources to be most promising. SRW wheat cultivars with moderate resistance to FHB include Freedom, Ernie, Truman, Bess, Roane, Tribute, and Jamestown (Gooding et al 1997; McKendry et al 1995, 2005, 2007; Griffey et al 2001, 2005, 2010). The current study used recombinant inbred lines (RILs) derived from two moderately FHB-resistant cultivars, Massey and Ernie, in the SRW wheat regions of the US with the following objectives: (1) map QTL associated with FHB resistance in Massey and Ernie using phenotypic data from multiple environments; (2) elucidate the main and epistatic effects of QTL and interactions between QTL and environments and; (3) determine the association between FHB resistance QTL with genes governing plant height, photoperiod sensitivity and awns, and their impact on breeding for FHB resistance.…”

In the soft red winter wheat (Triticum aestivum L.) regions of the US, Fusarium head blight (FHB, caused by Fusarium spp.) resistance derived from locally adapted germplasm has been used predominantly. Two soft red winter wheat cultivars, Massey and Ernie, have moderate resistance to FHB. Mapping populations derived from Becker/Massey (B/M) and Ernie/MO 94-317 (E/MO) were evaluated for FHB resistance and other traits in multiple environments. Eight QTL in B/M and five QTL in E/MO were associated with FHB variables including incidence, severity (SEV), index (IND), Fusarium damaged kernels (FDK), deoxynivalenol (DON), and morphological traits flowering time and plant height. Four QTL were common to both populations. Three of them were located at or near known genes: Ppd-D1 on chromosome 2DS, Rht-B1 on 4BS, and Rht-D1 on 4DS. Alleles for dwarf plant height (Rht-B1b and Rht-D1b) and photoperiod insensitivity (Ppd-D1a) had pleiotropic effects in reducing height and increasing FHB susceptibility. The other QTL detected for FHB variables were on 3BL in both populations, 1AS, 1DS, 2BL, and 4DL in B/M, and 5AL (B1) and 6AL in E/MO. The additive effects of FHB variables ranged from 0.4 mg kg−1 of DON to 6.2 % for greenhouse (GH) SEV in B/M and ranged from 0.3 mg kg−1 of DON to 8.3 % for GH SEV in E/MO. The 4DS QTL had epistasis with Ppd-D1, Qdon.umc-6AL, and Qht.umc-4BS, and additive × additive × environment interactions with the 4BS QTL for SEV, IND, and FDK in E/MO. Marker-assisted selection might be used to enhance FHB resistance through selection of favorable alleles of significant QTL, taking into account genotypes at Rht-B1b, Rht-D1a and Ppd-D1a.Electronic supplementary materialThe online version of this article (doi:10.1007/s00122-013-2149-y) contains supplementary material, which is available to authorized users.

“…Resistant lines included two moderately resistant lines 'P97397E1-11' and 'IL9624851-1' from the 2003 Northern Uniform Winter Wheat Scab Nursery that were developed at Purdue University and University of Illinois, respectively; two Chinese accessions, 'Ling Hai Mao Yang Mo', and 'Yang La Zi'; a South Korean cultivar 'Seu Seun 6'; and a newly purified source of Wangshuibai, acquired from the U.S. National Small Grains Collection at Aberdeen, Idaho and identified as having putative resistance genes in the University of Missouri's germplasm evaluation program supported by the USWBSI; two Romanian lines, 'Turda 95' and 'Fundulea 201R', introduced into the U.S. through a collaborative effort between the Center for Maize and Wheat Improvement in Mexico (CIMMYT) and the USWBSI; three sister lines from Hungary ('RR176', 'RR182' and 'RR243') acquired from Dr. Á kos Mesterházy; and three U.S. soft red winter wheat cultivars, including 'Ernie' and 'Truman' from the University of Missouri (McKendry et al 1995 and 'Freedom' from The Ohio State University (Gooding et al 1997) that serve as resistant check varieties in the U.S. Northern Fusarium Head Blight Nursery. Susceptible varieties included 'Patterson' (Ohm et al 1998), 'Pioneer variety 2545', and 'COKER 9835' which have served as susceptible check varieties in the U.S. Northern and/or Southern Winter Wheat Scab Nurseries and three additional susceptible or moderately susceptible breeding lines from the University of Missouri's wheat breeding program.…”

Additive gene action was important in determining FHBS for crosses among susceptible genotypes as evidenced by the strong correlation between FHBS of F 1 progeny and the mid-parental value of parents involved in the cross (r = 0.84; P \ 0.001), however, data from S/S crosses (Table 5) indicated that transgressive segregation was not important in this set of germplasm.…”

New sources of partial resistance to Fusarium head blight (FHB) in wheat have been identified over the past decade; however, little is known of their breeding value. A 20 parent partial diallel that included resistant genotypes from the U.S., Europe, China and South America was used to evaluate the potential of these sources of resistance as parents in wheat breeding programs. Eight plants replication -1 of each of 190 crosses and 20 parents were point-inoculated with Fusarium graminearum under greenhouse conditions in two replicated experiments. Both general (GCA) and specific combining ability (SCA) were significant. Most of the variance for FHB severity was associated with additive genes; however, estimates for SCA ranged from highly negative to highly positive in both resistant 9 resistant and resistant 9 susceptible crosses which suggest that improving FHB resistance through gene pyramiding strategies based on additive genetic variation may be complicated by interaction effects that condition FHB resistance.
