Screening of wheat genotypes for the presence of common bunt resistance genes

Common bunt is known to cause grain yield and quality losses in wheat due to bunt ball formation and infestation of the grain. The aim of this study is to identify for sources of resistance to common bunt in wheat genotypes using phytopathological and molecular methods. In general, studied 60 Kazakh and foreign wheat genotypes were found 15 samples with the Bt9, Bt8 and Bt11 genes. Carriers of the Bt10 gene include the five varieties. The four resistance genes, Bt8, Bt10, Bt11, Bt9, and Bt10 were identified in the Karasai variety. Phytopathological and molecular screening of Kazakh and foreign wheat genotypes selected 18 with genes for resistance to the disease. According to evaluation on an artificial infection 19 varieties showed an immune type of reaction. These varieties will be used in breeding programs as donors to create resistant varieties against the common bunt. Thus, approaches can reduce the level of fungicides use and the most effective method to control the common bunt.
