Yellow rust caused by Puccinia striiformis is one of the most harmful diseases in wheat worldwide. It can cause 10–70% yield loss. In Latvia, only periodic observations of yellow rust have been made. In recent years, epidemics of P. striiformis were observed in wheat-growing regions. New aggressive P. striiformisraces were identified. These races are adapted to high temperatures, produce more spores, and have a shorter latent period. This study aimed to identify the races of P. striiformis in Latvia. In 2017–2019, wheat leaves with symptoms of P. striiformis were collected. Wheat samples were sent to the Aarhus University Global Rust Reference Centre in Denmark for race identification with phenotyping and genotyping methods. During the research, the races of P. striiformis – PstS4, PstS7 (Warrior-), PstS10 (Warrior), PstS13 (Triticale2015) and PstS14 were identified.
