Abstract: Fusarium head blight(FHB)is one of the most destructive diseases in wheat,and Fhb1 is the main gene for FHB resistance. In order to screen the germplasms carrying Fhb1 gene in Huang and Huai winter wheat region,336 wheat cultivars from Hebei,Henan,Shandong,Shaanxi,Jiangsu and Anhui were detected by TaHRC-Kasp and His-InDel markers. Two cultivars(Shijiazhuang 75 and Zijingbai)from Hebei Province were screened to carry Fhb1 gene. Sequence analysis showed that the His gene sequences of these two cultivars were same as that of Sumai 3(FHB resistance type). Principal component analysis(PCA)of 336 materials was performed using 9 779 SNP loci and showed that Shijiazhuang 75 and Zijingbai had close genetic relationship with Jiangsu materials. Shijiazhuang 75 was bred in the early days of the founding of China. Zijingbai was a landrace in Hebei Province. These two materials carried Fhb1 gene,which indicated that Fhb1 gene might be distributed in some local germplasms in China at first. But it was eliminated under artificial selection pressure in the process of modern wheat breeding. The results of this study provided valuable genetic information and parent materials for FHB-resistant wheat breeding in Huang and Huai winter wheat region.
