Crown rust is a commonly occurring fungal disease of oat caused by Puccicnia
coronata Cda. F.sp. avenae P. Syd. & Syd. Oat crop loss caused by this pathogen ranged to
50%. The most effective, economical and environmentally friendly method for controlling crown
rust is growing resistant cultivars. The aim of presented study was characteristic of polish oat
cultivars. Objectives of presented study were 78 oat cultivars collected in Institute of Plant
Genetics, Breeding and Biotechnology University of Life Science in Lublin. The host-pathogen
tests were carried out on the first leaves of 10 days old seedlings using PK2010 isolate.
Obtained results shown that 3 oat cultivars (Borowiak, Celer and Krezus) were resistant to
PK2010 isolate in seedling stage. However, only Borowiak and Celer were resistant also in
adult plant stage. The rest of cultivars showed a susceptible or intermediate infection type.
