Higher Fusarium Toxin Accumulation in Grain of Winter Triticale Lines Inoculated with Fusarium culmorum as Compared with Wheat †
Resistance to Fusarium head blight in 32 winter triticale and 34 winter wheat accessions was evaluated. Triticale and wheat were sown in field experiments in two locations. At the time of flowering, heads were inoculated with three Fusarium culmorum isolates. Fusarium head blight index was scored and after the harvest percentage of Fusarium damaged kernels was assessed. Grain was analysed for t...
متن کاملComparison of Fusarium Culmorum Isolates Associated with Virulence on Wheat
Fusarium culmorum is one of the most important causal agents of Fusarium head blight (FHB), results in yield and quality reductions and mycotoxin accumulation. It predominates on cereals in North-West of Turkey in cereal growing fields. In this research the aggressiveness among the F. culmorum isolates and reduction on yield was evaluated. Two wheat varieties (Golia and Ceyhan) and 16 isolates ...
متن کاملThe Response of Selected Triticum spp. Genotypes with Different Ploidy Levels to Head Blight Caused by Fusarium culmorum (W.G.Smith) Sacc.
Several cultivars and pure lines of Triticum monococcum, T. dicoccon, T. polonicum, T. spelta and T. aestivum were inoculated with Fusarium culmorum, the causal agent of Fusarium head blight in wheat. During the three-year study, the infection decreased the values of the analyzed yield components: spike weight (by 5.6% to 15.8%), number of kernels per spike (by 2.8% to 11.8%) and one kernel wei...
متن کاملFungicides Application against Fusarium Head Blight in Wheat and Barley for Ensuring Food Safety
Fusarium head blight (FHB), or scab, caused by several Fusarium species, especially Fusarium graminearum Schwabe [teleomorph Gibberella zeae (Schweinitz) Petch], is a widespread and destructive disease of wheat (Triticum aestivum L.), barley (Hordeum vulgare L.), and other small-grain cereals (Liddell 2003; Parry et al. 1995; Pirgozilev et al. 2003). These pathogens infect spikes and reduce gra...
متن کاملInfection patterns in barley and wheat spikes inoculated with wild-type and trichodiene synthase gene disrupted Fusarium graminearum.
Fusarium head blight epidemics of wheat and barley cause heavy economic losses to farmers due to yield decreases and production of mycotoxin that renders the grain useless for flour and malt products. No highly resistant cultivars are available at present. Hyphae of germinating fungal spores use different paths of infection: After germination at the extruded tip of an ovary, the hyphae travel a...
