    Investigation and genome-wide association study for Fusarium crown rot resistance in Chinese common wheat
    (BioMed Central, 2019) Xia Yang; Yubo Pan; Singh, P.K.; Xinyao He; Yan Ren; Lei Zhao; Ning Zhang; Cheng Shun-He; Feng Chen
    Fusarium crown rot (FCR) is a severe and chronic disease in common wheat and is able to cause serious yield loss and health problems to human and livestock. Here, 234 Chinese wheat cultivars were evaluated in four greenhouse experiments for FCR resistance and genome-wide association studies (GWAS) were performed using the wheat 660 K genotyping assay. The results indicated that most cultivars evaluated showed FCR disease index (DI) of 40–60, while some cultivars showed stably good FCR resistance (DI < 30). GWAS identified 286 SNPs to be significantly associated with FCR resistance, of which 266, 6 and 8 were distributed on chromosomes 6A, 6B and 6D, respectively. The significant SNPs on 6A were located in a 7.0-Mb region containing 51 annotated genes. On the other hand, QTL mapping using a bi-parental population derived from UC1110 and PI610750 detected three QTLs on chromosomes 6A (explaining 7.77–10.17% of phenotypic variation), 2D (7.15–9.29%) and 2A (5.24–6.92%). The 6A QTL in the UC1110/PI610750 population falls into the same chromosomal region as those detected from GWAS, demonstrating its importance in Chinese materials for FCR resistance. This study could provide useful information for utilization of FCR-resistant wheat germplasm and further understanding of molecular and genetics basis of FCR resistance in common wheat.

    Characterization of Fusarium head blight resistance gene fhb1 and its putative ancestor in Chinese wheat germplasm
    (Institute of Crop Sciences, 2018) Zhanwang Zhu; Dengan Xu; Cheng Shun-He; Chunbao Gao; Xianchun Xia; Yuanfeng Hao; He Zhonghu
    Enhancing resistance to Fusarium head blight (FHB) has become one of important breeding objectives in the major wheat-growing regions in China. A prominent locus Fhb1 conferring stable FHB resistance with the largest effect is the major source of resistance in wheat breeding. Understanding the distribution and putative donor of Fhb1 in Chinese wheat cultivars will facilitate the application of this gene and thus benefit FHB resistance breeding in China. Haplotype analysis of PFT (pore-forming toxin-like), HC (HCBT-like defense response protein) and His (histidine-rich calcium-binding protein) genes in the Fhb1 region of 229 wheat cultivars and advanced lines indicated that PFT-I/His-I was a resistant haplotype. Both pedigree and marker (or sequence) information revealed that Fhb1 in Chinese wheat cultivars was mainly derived from Sumai 3 and Ningmai 9, in which Ningmai 9 was the major donor. The Fhb1 diagnostic markers PFT-CAPS and His-InDel developed in this study can be used effectively in marker-assisted selection for improving FHB resistance.
