Resumen:
The aim of this study was to examine the responses of wheat and barley varieties to inoculation by different Fusarium poae isolates to observe the contamination of this fungus in grains. The experimental analyses were performed during 3 years under natural conditions. Statistical analyses were made and re-isolated isolates were tested by a primer-specific PCR reaction and by comparing DNA-ISSR amplifications. Only in 2008 differences among varieties in fungal symptoms were statistically significant. Although the number of re-isolated isolates in wheat varieties was higher than the number of observed symptoms no correlations were found. However, in barley we found correlations and the linear regression analyses allow us to suggest that for one grain with visual symptoms two barley grains could contain the fungus.
