Reports on the effectiveness of Fusarium head blight (FHB) control measures do not follow the same pattern in different regions, and the combined effects of abiotic and biotic factors on FHB are not fully understood. Consequently, the main objective of this study was to examine divergence in susceptibility reactions of winter wheat genotypes to FHB when exposed to the combined effects of cultivation practices, cultivar properties, year and the presence of interacting Fusarium spp. as an inherent whole. Analysed data originated from 633 grain samples collected from 434 localities in an eight-year period as a part of investigations related to the development of the DONcast® Europe prediction model. This study suggests that ploughing could increase the risk of the occurrence of less frequent toxigenic Fusarium species. Stubble management generated more divergent environmental factors than no-till farming, influencing greater variability in the relationship between deoxynivalenol (DON) accumulation and grain infection. The results of this study indicated differences in susceptibility reactions of varieties to FHB and suggested that more attention should be focused on the specificity of the interaction between variety and combined environmental stressors to ensure more predictive and sustainable wheat production.

栽培方式对冬小麦基因型对枯萎病敏感性敏感性多样性的影响

关于镰刀菌枯萎病控制措施有效性的报告在不同地区没有遵循相同的模式,并且非生物和生物因子对FHB的综合影响尚不完全清楚。因此,本研究的主要目的是检验在种植实践,品种特性,年份和相互作用的镰刀菌属的综合影响下,冬小麦基因型对FHB敏感性反应的差异。作为一个固有的整体。作为与DONcast®Europe预测模型发展有关的调查的一部分,分析数据来源于在八年内从434个地方收集的633个谷物样品。这项研究表明,耕作可能会增加发生不频繁的毒物的风险。镰刀菌属。与免耕耕作相比,留茬管理产生了更多不同的环境因素,从而影响了脱氧雪腐烯醇(DON)积累与谷物感染之间关系的更大变异性。这项研究的结果表明了变种对FHB的敏感性反应存在差异,并建议应将更多注意力集中在变种与组合环境胁迫因子之间相互作用的特异性上,以确保更可预测和可持续的小麦生产。
