“…Using SSR analysis in this study, 59 maize hybrids could be placed into eight SSR groups. This observation was similar to Nikhou et al (2013) and Xu et al (2013) indicating that SSRs are efficient markers to classify closely-related maize lines. In other words, SSR markers were able to detect the extent and considerable level of genetic diversity in maize hybrids.…”

Fusarium ear rot in maize (Zea mays L.) is a serious disease in all maize-growing areas worldwide. A total of 454 fungal strains were isolated from 69 commercial maize hybrids grown in Harbin, China, and comprised Fusarium subglutinans (34.8%), F. proliferatum (31.3%), F. verticillioides (20%), F. graminearum (9.7%), and F. equiseti (4.2%). Among them, a complex of multiple species, F. subglutinans, F. proliferatum, and F. verticillioides are the dominant fungi causing ear rot. Among 59 commercial maize hybrids, eleven hybrids (18.6%) were found to be highly resistant to Fusarium ear rot. Simple sequence repeat (SSR) analysis using six pairs of primers resulted in 24 reproducible bands and cluster analysis separated the maize hybrids into eight groups. There was little genetic variation associated with disease resistance. No correlation was found between genetic diversity and disease resistance.

“…However, the population structure of Fusarium that causes ear rot in maize varies widely across countries and regions. The dominant species was F. verticillioides in Switzerland, Poland, Ethiopia, Iran, and Eastern China; F. graminearum in France and Belgium; and F. subglutinans in the Harbin area of China [16,18,20,25,28,41,[53][54][55]. The frequency and distribution of Fusarium species varied among provinces and sites, which was closely related to environmental conditions [41].…”

Ear rot caused by the Fusarium species has led to a decline in maize yield and kernel quality worldwide. The changes in the population structure of pathogens and the widespread planting of susceptible maize varieties have exacerbated the occurrence and harm of ear rot in China. Therefore, it is very important to establish the species composition of Fusarium and evaluate the resistance of the main cultivated hybrids. In this study, 366 single conidial isolates of Fusarium spp. were obtained from three provinces of Northeast China. F. verticillioides, F. subglutinans, F. proliferatum, F. oxysporum, and F. graminearum species complex (FGSC) were identified, with F. verticillioides being the most prevalent with a frequency of 44.0%. Based on the TEF-1α gene sequences analysis, the FGSC populations consisted of two independent species: F. boothii and F. graminearum, which account for 23.8% and 5.7% of the total isolates, respectively. Additionally, the resistance to ear rot by 97 maize hybrids commonly planted in Northeast China was evaluated by inoculation with F. verticillioides during 2021 and 2022. The results showed that the disease parameters of different hybrids varied significantly (p < 0.05). Approximately half of the hybrids had damage rates ranging from 0 to 15%, and 79.4% of the hybrids had a severity rating of less than 5.5. In total, 49 (50.5%) hybrids were rated as moderately resistant, which was the dominant resistance category, and 71 hybrids (73.2%) were identified as moderately to highly resistant to ear rot. Current research confirms that Fusarium ear rot in maize is mainly caused by F. verticillioides in Northeast China, and many hybrids are resistant to the disease. This study will guide growers to scientifically deploy resistant commercial hybrids to control ear rot.

“…The other common fungal disease in maize is Fusarium Ear Rot, which is mainly caused by Fusarium verticillioides [ 14 , 15 ]. Similarly to A. flavus , the F. verticillioides species has been reported as a worldwide fungal pathogen of maize kernels.…”

Maize is frequently contaminated with multiple mycotoxins, especially those produced by Aspergillus flavus and Fusarium verticillioides. As mycotoxin contamination is a critical factor that destabilizes global food safety, the current review provides an updated overview of the (co-)occurrence of A. flavus and F. verticillioides and (co-)contamination of aflatoxin B1 (AFB1) and fumonisin B1 (FB1) in maize. Furthermore, it summarizes their interactions in maize. The gathered data predict the (co-)occurrence and virulence of A. flavus and F. verticillioides would increase worldwide, especially in European cold climate countries. Studies on the interaction of both fungi regarding their growth mainly showed antagonistic interactions in vitro or in planta conditions. However, the (co-)contamination of AFB1 and FB1 has risen worldwide in the last decade. Primarily, this co-contamination increased by 32% in Europe (2010–2020 vs. 1992–2009). This implies that fungi and mycotoxins would severely threaten European-grown maize.
