摘要
The objective of this work was to evaluate quantitative-genetic parameters of Fusarium graminearum and F. verticillioides resistance and their related mycotoxin contents (deoxynivalenol, zearalenone and fumonisin, respectively). Significant genotype and genotype by environment effects were found. Phenotypic correlations between severity and mycotoxin contents were moderate to very high promising efficient indirect selection for reduced mycotoxin content via severity rating. Correlation between a F. graminearum and F. verticillioides inoculated set of 60 inbred lines was moderate, but genotypes resistant to both pathogens exist.
