中文摘要：为了评估加拿大东部感染了赤霉病的燕麦(Avena sativa L.)其籽粒受脱氧雪腐镰刀菌烯醇（DON）污染的严重性，检测了3243个燕麦粒样品，包括160个87年进行基因型检测、2008到2015年在加拿大魁北克和大西洋（海滨诸省）地区注册和推荐试用的燕麦中的DON。研究表明培育赤霉病抗性品种，从DON污染较少的角度来衡量，应该是该地区燕麦育种的一个组成部分。
外文摘要：To assess the severity of deoxynivalenol (DON) contamination in oat (Avena sativa L.) grain from infection of Fusarium head blight in eastern Canada, DON were determined for 3243 oat grain samples, involving 160 oat genotypes tested in 87 year–location combinations in Quebec and Atlantic Canada (Maritimes) oat registration and recommendation trials from 2008 to 2015. Analysis of the data led to the following findings. First, there are repeatable genetic differences in DON contamination. Relatively resistant cultivars (e.g., ‘CDC Dancer’) and susceptible cultivars (e.g., ‘AC Rigodon’) were identified. Genotypes better than CDC Dancer or worse than AC Rigodon were also identified. Second, cultivars with less DON contamination tended to have thinner hulls, i.e., greater groat percentage. Third, oat grain produced in Quebec and Maritimes was generally safe for use as feed or food, according to the Canadian permissible DON limits. In about 16% of the trials, however, the grain may not be suitable for making infant food according to the EU limit. Using a resistant cultivar such as CDC Dancer can reduce this risk to 10%, while using a susceptible cultivar such as AC Rigodon can increase the risk to 21%. Breeding for Fusarium head blight resistance, as measured by less DON contamination, should be a component in oat breeding for the region.
