Fusarium head blight(FHB)is one of the most important diseases in wheat.The effect of the major FHB resistance gene Fhb1 on 3BS is relatively stable.Consequently it is the most important locus for breeding FHB resistant germplasms.Huangfangzhu(HFZ)is a Chinese wheat landrace with superior resistance to FHB and also has Fhb1 on 3BS.In this study,two heterozygote-derived subpopulations(HDP)were developed from the lines L30 and L112that were heterozygous at Fhb1 in a population of recombinant inbred lines(RIL)...
