Abstract
Common bunt Tilletia caries (D.C.) – is one of the most significant biotic restraints in wheat production around the world. Using phytopathological and molecular methods, the identification of Bt -genes in 43 Kazakh and foreign winter wheat cultivars was carried out. The phytopathologicalevaluation of resistance to common bunt on an infectious background allowed selecting a number of resistant cultivars to Tilletia caries (D.C.). The cultivars Ati, Bereny, Koros, Hajnal, Feny, Pilis, Petur, Szala, Vitorlás, Rege, Raba, Rozi,Akbiday, Azharly, Batyr, Bezostaya 1, Bulava andAlmalyshowed levels of resistance. Intermediate resistant cultivars: Bekes, Kalasz, Mentor, Goncol, Csillag, Garaboly, Alihan, Аdyr, Altynshash, Arap, Bogurnaya 56, Botagoz, Derbes. Moderately susceptible cultivars wereTisza, Futar, Alatau, Aliya, Aktereksky, Ania and Daulet. The susceptible cultivars were Szemes,Akdan, Anara, Bayandy and Dana. Molecular screening of wheat samples for the presence of Bt9 and Bt10 resistance genes using microsatellite (SSR) markers FSD/RSA and Xgpw 7433was carried out. Bt9 gene in four cultivars of wheat (Bereny, Petur, Raba and Akbiday) were detected, and Bt10 in seven cultivars (Ati, Bereny, Koros, Petur, Batyr, Almaly, Bezostaya 1) was identified. As a result of phytopathological and molecular studies common bunt resistance carriers of wheat cultivars Bereny, Petur, Raba Akbiday, Ati, Koros, Batyr, Almaly, Bezostaya 1 were identified. The most valuable donors of resistance to Tilletia caries are the cultivars Bereny and Petur, in which 2 resistance genes (Bt9 and Bt10) were identified. The results for MAS-breeding to increase resistance to common bunt of wheat cultivars can be used.
