Resistance against Fusarium head blight in oats

Popis výsledku v původním jazyce

Twenty-nine common oat (Avena sativa L.) cultivars were used for Fusarium head blight (FHB) resistance assessment during 2015-2017. The cultivars evaluated for FHB resistance were planted in hill plots (sowing into 15 cm circles 25 cm apart) in three replications and two variants (infected and uninfected). The plants were inoculated with a conidial suspension consisting of a mixture of Fusarium poae, F. graminearum and F. culmorum. The visual symptom score (VSS) was evaluated 14 days after inoculation. Yield tolerance to infection was determined by percentage reduction relative to non-inoculated control for the traits thousand grain weight (TGWR) and grain weight per panicle (GWPR). Seeds from infected spikes were analysed for deoxynivalenol (DON) as well as T-2 plus HT-2 toxin contents. It was found that determination of mycotoxin content in grain is necessary in order to fully describe the state of resistance against FHB in oats. Naked oat (A. nuda L.) cultivars were found to have higher resistance levels for all the tested traits and also lower concentrations of mycotoxins. Naked oat cultivars Kamil, Tibor, Izak, Otakar, Vjatskii, OA 504-6, Saul, Avenuda, Gana and Aldan showed higher levels of resistance against FHB for of all the evaluated traits. The lowest concentration of DON was determined in the cultivar Vjatskii. The weather conditions significantly influenced the development of infection in individual years and traits related to FHB resistance.
