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.plUznanie autorstwa-Użycie niekomercyjne 3.0 Polskaowies zwyczajnyPuccinia coronatardza koronowatesty żywiciel–patogencommon oatcrown rusthost-pathogen testPuccinia coronateDyscyplina::Nauki rolniczeArticle2300-5378
