Abstract
Rye is a strategically important crop in Russia, which is less demanding than other crops on soil fertility, mineral nutrition conditions and plant protection measures. Monitoring of the phytosanitary condition of winter rye varieties is a necessary measure for its stable yield. Four varieties of domestic selection Secale cereale L. (Nika, Vikras, Parom and Chusovaya), grown in the conditions of the Middle Urals in the experimental fields of the Perm and Ural Research Institute, PCR diagnostics of viral infections was carried out. RNA samples of 4 varieties of winter rye were analyzed by real-time PCR for infection with the Barley yellow dwart virus (BYDV) and the Wheat streak mosaic virus (VSMV). Barley yellow dwart virus was diagnosed in 60% of all studied samples of winter rye leaves, and wheat streak mosaic virus was diagnosed in 15% of the studied samples. The most resistant to the barley yellow dwart virus of barley leaves is the variety of winter rye Chusovaya, since it is infected only in the field of the Perm Research Institute. Varieties Nika 3, Vikras and Chusovaya are the most resistant to the wheat streak mosaic virus. A variety of winter rye was infected with this virus by Parom (30%). Further monitoring of the phytosanitary situation and profiling of viral infections of winter rye varieties in the territory of the Middle Urals is necessary.
