Abstract
Crop diseases have a significant impact on crop yields and quality worldwide. For decades, the threats from diseases and pests of crops have become more serious in the context of global climate change, which creates a problem for our food production. In recent years, there has been an increasing spread and harmfulness of stripe rust in Kazakhstan. Most of the commercial wheat cultivars currently grown in Kazakhstan are still susceptible to rust diseases. The aim of the study is to monitor the development of stripe rust and to identify new sources of resistance to Puccinia striiformis Westend f. sp. tritici using modern genetic breeding methods. According to the monitoring results, the spread and development of stripe rust was at an average level (48-52%). Phytopathological screening revealed 57 samples of winter wheat (76.0%) with an immune type of reaction to stripe rust. 22 promising specimens were identified that showed a resistant and moderately resistant type of response to diseases and are characterized by the presence of several resistance genes. Based on the results of this study, selected promising lines of winter wheat are of interest for a wheat breeding program for resistance to stripe rust.
