The evaluation of synthetic hexaploid wheat (HSW) conducted on the experimental fields of the Kazakh Research Institute of Farming and Plant growing according to generally accepted methods in plant pathology and plant growing. The germplasm accessions originated from six winter durum wheat parents and 10accessions of Aegilopstauschiifrom Azerbayjan, Iran and Russia. The most superior lines were characterized by resistance to stripe rust, common bunt, tall structure (110-120 sm), big size of grain and spikes, and higher productivity comparative with commercial wheat cultivars. For leaf rust 16 out of 33 lines of HSW showed resistance and moderate resistance, 11 lines were moderate susceptible 6-24%, 3 lines were susceptible to leaf rust (25-50%). For stripe rust 15 out of 33 lines of HSW showed resistance, 5 lines showed moderate resistance, 7 lines moderate susceptible 10-40%, 3 lines were susceptible to stripe rust (50-60%).
