Název v původním jazyce

Evaluation of barley resistance to Fusarium head blight infection and mycotoxin contaminatiom of grain

Popis výsledku v původním jazyce

The results are based on field infection trials with six spring barley cultivars registered in the Czech Republic and resistance sources Chevron and CI 4196. In experiments at two locations (Ruzyně, Kroměříž) lasting for two years two inoculation techniques were applied (spraying and brushing of inoculum). Four isolates of Fusarium culmorum and Fusarium graminearum were used for inoculations by brushing technique at the location Ruzyně. Highly significant and positive correlations between determinationsof DON content by ELISA and GC method were obtained for all isolates. One isolate of F. graminearum was predominant nivalenol producer, while the other isolates were deoxynivalenol (DON) producers. From the other mycotoxins 3-AcDON was found in grain atrelatively higher concentration, particularly after inoculation with F. culmorum isolates. Significant cultivar differences in DON content, examined yield traits, percentage of Fusarium colonies and percentage of non-sprouting grains wer
