The aim of this study was to identify wheat germplasm resistant to heavy metals (lead, copper, zinc and cadmium), which are important to eastern Kazakhstan region and identification of donors for breeding and promising forms of wheat that are resistance to heavy metals and destined for agricultural production. Different genotypes of winter wheat, the world's collection (Kazakh, Russian, a collection of CIMMYT cultivars and lines of winter wheat, wild species of wheat) were studied. Field studies carried out for the determination of physiological parameters. Heavy metals in soil and plant samples were determined by atomic absorption spectrophotometry. Genotypic differences in the accumulation of copper, lead, cadmium and zinc were established. The smallest number of studied heavy metals accumulates in the seeds of varieties of winter wheat Mironovskaya-808 and Krasnovodopadskaya-25. The highest yield from plots has winter wheat Mironovskaya-808. A crop yield of plants is connected with their ability to quickly enter to the tillering stage, successfully overwinter, preserve during the summer vegetation. Variety of winter wheat Mironovskaya-808 can be recommended for cultivation in the technologically disadvantaged regions, with soil contamination by heavy metals, as they accumulate not much heavy metal, they have good indicators of development, overwintering, yield.
