The species composition of the genus associated with Fusarium head blight (FHB) in wheat fields of Hungary in the year 2019 was assessed. Symptomatic wheat heads were collected at 20 geographical locations representing different ecosystems. A total of 256 strains were isolated and identified by partial sequences of the translation elongation factor 1-alpha gene and, where required, the second-largest subunit of the DNA-directed RNA polymerase gene. Overall, (58.2%) proved to be the dominant species, followed by (formerly ) (17.2%) and (7.4%). The presence of all other species, including , in the population was less than 5%. was identified as the main species associated with FHB at 14 sampling sites. Fumonisin-producing , primarily known as the pathogen of maize in Hungary, was detected nearly as frequently as at three locations and dominated at two other sites. was not found during the survey. , a species that is believed to be of Asian origin and was already found in Hungary in 2002, was identified at two locations.
对 2019 年匈牙利小麦田中与镰刀菌穗腐病相关的 属的物种组成进行了评估。在代表不同生态系统的 20 个地理位置采集了出现症状的麦穗。共分离并鉴定了 256 株菌，方法是使用翻译延伸因子 1-α 基因的部分序列，以及必要时使用 DNA 指导的 RNA 聚合酶基因的第二大亚基。总的来说， （58.2%）被证明是优势物种，其次是 （前身为 ）（17.2%）和 （7.4%）。其他所有物种的存在，包括 ，在种群中的比例都低于 5%。 在 14 个采样点被确定为与 FHB 相关的主要物种。产伏马菌素的 ，主要是匈牙利玉米的病原体，在三个地点的检测频率几乎与 一样高，在另外两个地点占主导地位。 在调查期间未发现 。 ，一种被认为起源于亚洲的物种，已于 2002 年在匈牙利发现，在两个地点被鉴定出来。
