中文摘要:本研究评估了四种小麦种质,包括面包小麦(新、老品种)、斯佩耳特小麦、二粒小麦及一粒小麦的赤霉病(FHB)抗性,并分析了镰刀菌穗感染、粒损伤及籽粒中单端孢霉烯毒素(脱氧雪腐镰刀菌烯醇、雪腐镰刀菌烯醇)的积累。研究发现四种小麦的所有类型其抗性都具有广泛的变异性。并鉴定了抗FHB及籽粒中毒素积累的种质。
外文摘要:Fusarium head blight (FHB) resistance was evaluated for accessions of four Triticum species, including bread wheat (modern and old cultivars), spelt, emmer, and einkorn. Fusarium head infection, Fusarium kernel damage and accumulation of trichothecene toxins (deoxynivalenol, nivalenol) in grains were analysed. Modern bread wheat cultivars were the most susceptible to head infection, and emmer and einkorn accessions were the most resistant. Kernel damage was the least for emmer and spelt and greatest for bread wheat. No significant differences between the four host species were observed for toxin accumulation. However, the greatest amounts of deoxynivalenol were detected in the grains of modern wheat cultivars and the least in old bread wheat cultivars. The greatest amount of nivalenol was detected in einkorn grains and the least in old bread wheat cultivars. Wide variability of resistance of all types in all four species was observed. Accessions resistant to FHB and toxin accumulation in grains were identified.
