摘要

A survey was conducted in southern Alberta, Canada, to collect Fusarium stalk rot and Fusarium head blight (FHB) disease samples from corn and wheat fields, respectively, with an aim to understand the diversity in the population of Fusarium graminearum. From 77 wheat and 80 corn samples, 79 isolates of F. graminearum were obtained. These 79 isolates were evaluated for their growth rate, sporulation ability, pathogenicity and trichothecene genotype. Eighty-two percent of the isolates were recovered from corn, which suggests corn residue may be better suited than wheat for perpetuating the FHB pathogen. Three genotypes with potential of producing 3-ADON, 15-ADON and NIV were present in the population, and among them, 15-ADON producing genotype was predominant, and 3-ADON genotype produced more spores than the 15-ADON genotype. The proportion of 3-ADON genotype is increasing overtime in Alberta. The impact of increasing population of 3-ADON genotype is worthy of to be monitored for the management of FHB. There were variations in the population of F. graminearum isolates for growth rate, sporulation and pathogenicity but revealed no association among the parameters suggesting other factors like host susceptibility and environment play a significant role in the development of FHB.

Graminearum。评估这些79个分离株的生长速率，孢子化能力，致病性和三胞内癸二型基因型。从玉米中回收八十二个分离株，这表明玉米残余物可能比小麦更适合延伸FHB病原体。在人口中存在具有产生3-Adon，15-Adon和Niv的潜力的三种基因型，其中，其中15-Adon产生基因型是主要的，3-Adon基因型产生比15-Adon基因型更多的孢子。 3-Adon基因型的比例在艾伯塔省的加班时越来越多。增加3-Adon基因型人群的影响值得监测用于FHB的管理。对于生长速率，孢子率和致病性的F. Graminearum分离物的群体存在变化，但揭示了诸如宿主敏感性和环境等其他因素的参数之间的关联在FHB的发展中起着重要作用。
