Wheat and barley resistance to head smut

Abstract

In the conditions of the central part of the Krasnoyarsk forest-steppe, the resistance of 114 varieties and lines of spring common wheat and spring barley to regional populations of loose smut U.tritici and U.nuda was studied for 3 years. The studied samples in the phase of the beginning of flowering were infected by a syringe with a 0.005% suspension of the pathogen chlamydospores. Pathogen damage was recorded according to the VIR scale after the manifestation of visible symptoms of the disease. The sources of resistance to the disease were identified varieties and lines of barley and wheat, the defeat of which by loose smut did not exceed 5%. These are 41 samples of wheat: varieties Rifor 6, Mandaryna, Lutetia, Stepnaya 53, Rifor 1, Aleksandrit, Arabeska, Partyzan, Yubileinaya 60, Saratovskaya 76, KWS Buran, Orenburgskaya Yubileinaya, Maestro, H 16-2, LT-12, Arsey, Anabel, Grechanka, Barakat, LT-8, Krasnoyarskaya 12, Beyskaya, Uyarochka, Altaiskaya 70, Kanskaya, Omskaya 36, Novosibirskaya 31, breeding lines K-733-3, K-790-6, KP-6, KSI-21, K-943-1, K-782-2, K-868-1, K-734-10, K-693-2, KSI-10, KP-5, K-696-7, KP-4. And also 12 samples of barley: varieties Emelya, Kedr, Agul 2, Sobolek, lines D7-7040, D50-7468, D36-7289, D22-7177, Zh9-7553, Zh9-7550, Zh37-7621, V-56-6885 .
