Abstract: 【Objective】 To clarify the distribution of fusarium head blight resistance genes Fhb1 and Fhb7 in Huaibei wheat,in Jiangsu Province. To provide a basis for breeding resistance lines to fusarium head blight. 【Methods】 In 155 novel wheat lines from Huaibei,the genotypes of diagnostic molecular markers Fhb1 and dominant molecular markers Fhb7 of wheat main fusarium head blight resistance genes were analysed. 【Results】 Resistance genes Fhb1 and Fhb7 were both distributed in the 155 novel wheat lines. The frequency of Fhb1 was higher than that of Fhb7. Among the 4 genotypes,fhb1/Fhb7 gene combination did not appear,151 lines containing fhb1/fhb7 gene combination,accounted for 97.4% of the total,3 lines containing Fhb1/fhb7 gene combination,accounted for 1.9%. There was only one line with Fhb1/Fhb7 genotype containing the two resistance genes,accounted for 0.7%. 【Conclusion】 The Fhb1 and Fhb7 genes were less distributed in the novel wheat lines in Huaibei,Jiangsu Province.

Key words: Wheat, Fusarium head blight, Resistance gene, Fhb1, Fhb7
