“…A possible reason is that different Q alleles are present in durum vs. common wheat, which was supported by results of Jantasuriyarat et al [ 51 ] and Faris [ 50 ]. Like in Buerstmayr et al [ 21 ], this locus also contributed to spike compactness in the current study, explaining 23% phenotypic variation (data no shown); but it was not associated with strong FHB resistance as in Buerstmayr et al [ 21 ], Chu et al [ 52 ], and Zhang et al [ 53 ].…”

Fusarium head blight (FHB) resistant line Soru#1 was hybridized with the German cultivar Naxos to generate 131 recombinant inbred lines for QTL mapping. The population was phenotyped for FHB and associated traits in spray inoculated experiments in El Batán (Mexico), spawn inoculated experiments in Ås (Norway) and point inoculated experiments in Nanjing (China), with two field trials at each location. Genotyping was performed with the Illumina iSelect 90K SNP wheat chip, along with a few SSR and STS markers. A major QTL for FHB after spray and spawn inoculation was detected on 2DLc, explaining 15–22% of the phenotypic variation in different experiments. This QTL remained significant after correction for days to heading (DH) and plant height (PH), while another QTL for FHB detected at the Vrn-A1 locus on 5AL almost disappeared after correction for DH and PH. Minor QTL were detected on chromosomes 2AS, 2DL, 4AL, 4DS and 5DL. In point inoculated experiments, QTL on 2DS, 3AS, 4AL and 5AL were identified in single environments. The mechanism of resistance of Soru#1 to FHB was mainly of Type I for resistance to initial infection, conditioned by the major QTL on 2DLc and minor ones that often coincided with QTL for DH, PH and anther extrusion (AE). This indicates that phenological and morphological traits and flowering biology play important roles in resistance/escape of FHB. SNPs tightly linked to resistance QTL, particularly 2DLc, could be utilized in breeding programs to facilitate the transfer and selection of those QTL.

Fusarium head blight (FHB) mainly caused by Fusarium species is one of the most important diseases threatening worldwide wheat production. To develop new FHB resistance resources, disease resistances of three new wheat lines L958, L962 and L987 were evaluated over a period of several years. We employed L699 (PI672540) and L661 as the resistant and susceptible control, respectively. Moderate FHB resistance was observed in these three wheat lines, among which the genotype L958 was found a good resource for yield, quality and FHB resistance improvement. In addition, genotype L962 was found to be resistant to powdery mildew, and both L958 and L987 carried the YrL693 gene conferring stripe rust resistance. The study provides promising results for accelerating the resistance breeding of the three wheat lines. Keywords: agronomic trait; FHB; resistance evaluation; Triticum aestivumFusarium head blight (FHB), mainly caused by Fusarium graminearum Schwabe and F. culmorum WG Smith, is a serious wheat (Triticum aestivum L.) disease worldwide (Bai & Shaner 2004;Li et al. 2017). In China, FHB epidemics have frequently occurred in the middle to lower valleys of the Yangtze River (Yao & Lu 2000). In recent years, FHB has spread to the southwest of China, including Sichuan Province (Zhang et al. 2011;Liu et al. 2015;Yang et al. 2016), where the climate was warm and rainy. Furthermore, FHB is also a fungal disease threatening food and economic security due to its contamination with mycotoxins, decreasing the wheat yield and quality (Zwart et al. 2008). At present, there is still no economic and effective way to control this disease. Developing resistant cultivars is an important approach to control this disease, for which the decisive step is to identify new germplasm with multi-resistance.Some effective FHB resistance sources have been identified in common wheat (Chu et al. 2011), and some FHB resistance quantitative trait loci (QTLs) have also been found and mapped in wheat relatives (Cai et al. 2005;Chen et al. 2007).

In addition, four new FHB resistant wheat germplasms were identified and released , which demonstrated the possibility of using Th. intermedium to develop novel wheat germplasm with different disease resistance. However, some breeding problems still remain and new materials with effective resistance to various diseases need to be developed.The research in this paper is aimed at screening wheat FHB resistance germplasm derived from an MY11 × YU25 cross for FHB resistance improvement.

Production of doubled haploids (DHs) is an important methodology to speed the process of breeding and development of mapping populations in crops. The procedure for DH production includes two major steps: haploid induction and chromosome doubling. In recent years, wide hybridization between wheat and maize has become a main approach for haploid production in wheat. In this method, the maize chromosomes are completely eliminated during the early development of the hybrid seeds after wheat spikes were pollinated with maize pollen. Numerous wheat cultivars and mapping populations have been developed using wheatmaize hybridization. In this study, we review the procedures of DH production of durum and common wheat via wide hybridization with maize, the factors which affect the efficiency of DH production, and the mechanism of selective elimination of the maize genome during the early development of the hybrid embryos. We also report a highly efficient protocol for DH production in durum and common wheat, which was established based on the optimal conditions for each of the factors that affect the efficiency of DH production.Key words: doubled haploid production -wide hybridization -chromosome elimination -chromosome doublingcommon wheat -durum wheat Doubled haploids (DHs) in plants have complete homozygosity, which can be achieved in one generation from hybrid plants. Thus, using the DH method could speed cultivar and population development in crop improvement, genetic manipulation, and plant genome and gene mapping. The procedure for DH production includes two major steps: haploid induction and chromosome doubling. Chromosome doubling of haploid plants has been routinely and successfully performed using colchicine. However, the success and efficiency of haploid induction varies in different crop species. The successful utilization of the DH method in most crops to breed commercial cultivars and to develop mapping populations relies highly on an efficient protocol for inducing haploids.Haploids in higher plants can occur spontaneously. They can also be artificially induced in vivo or in vitro by androgenesis and gynogenesis. The first report of the natural occurrence of sporophytic haploids was in the weed species Datura stramonium L. (Blakeslee et al. 1922). Later, the development of protocols for the production of haploid plants and the techniques of chromosome doubling led to the release of two DH cultivars in 1972 and 1980, respectively: 'Maris Haplona' in rapeseed (Brassica napus L.) using microspore culture and 'Mingo' in barley (Hordeum vulgare L.) using genome elimination (Thompson 1972, Ho andJones 1980). In the late 1970s, DH technology developed slowly because of its labour and time-consuming process (Forster et al. 2007). But in recent years, technological innovation and the high demand of the end-use applications of DH lines, such as used for marker identification and gene mapping, drew attention to the development of DHs in higher plants (Forster et al. 2007).Durum wheat (Triticum turgidum L. su...
