摘要: Fusarium head blight of wheat is an extremely damaging disease, causing severe losses in seed yield and quality. The objective the current study was to examine characterize alternate sources resistance (FHB). Ninety-one F1-derived doubled haploid lines from cross Triticum aestivum 'Wuhan-1' × 'Maringa' were examined for disease reaction graminearum by single-floret injection replicated greenhouse trials spray inoculation field trials. Field experiments also used collect agronomic spike morphology characteristics. Seed samples plots deoxynivalenol (DON) determination. A total 328 polymorphic microsatellite loci construct a genetic linkage map this population together these data identify QTL controlling FHB resistance, accumulation DON, traits. analysis identified different types o...
