Puccinia graminis f. sp. tritici races identified on wheat and Berberis spp. in northern Turkey

Abstract

Wheat is a commonly grown crop in Turkey. Rust diseases are among the most important biotic factors affecting wheat yield and quality. Stem rust of wheat caused by Puccinia graminis f. sp. tritici is one of the oldest known diseases of wheat. Wheat stem rust is common in Kastamonu province located in the northern part of Turkey. In addition, Berberis species are also common in Kastamonu province. In this study which was conducted in 2016 and 2017 in Kastamonu province, stem rust races occurring on Berberis species and wheat plants were determined. Forty single pustule aeciospores from Berberis plants were obtained. The most common stem rust race originating from Berberis plants was TTTTF. Other stem rust races from Berberis plants were RTTTF, RTTTC, TTTTC, and TTKTF. From wheat, 74 single pustule isolates of stem rust were obtained. The most common stem rust race originating from wheat was also TTTTF. Other stem rust races from wheat plants were TTKTF, TTTTC, TTKTC, RTTTF, and RTTTC.
