Unique features of Myronivs’ka 808 variety have provided its triumph in agricultural production in the former Soviet Union and other countries. Myronivs’ka 808 has become one of the most popular varieties in terms of sown areas (in 1971 over 9.5 million hectares) in the world production. Up to now the variety has been cultivated in the Russian Federation and the Republic of Kazakhstan. Myronivs’ka 808 variety gained leadership in the global selection process as a source of high grain quality, high productivity, general adaptability and plasticity. Using germplasm of this variety enabled to develop over 400 wheat varieties including 350 winter varieties and 60 spring varieties.

As a result of the lead long-term selection works wint involving a World' s collection and intertype and intertype hybridization with purposeful selection on economic-biological attributes highly productive • grades of a winter wheat, with stability to various kinds of illnesses and high technological qualities of grain have been allocated. The adapted grades of a winter wheat for a various environment of various zones of the countries of the Central Asia that allows to realize potential opportunities of grades in different environments of cultivation and by that to prevent losses of a crop from biotic and abiotic stresses that allows to stabilize productivity and adaptability of culture in a zon winter husbandry are created. The long-term field experiences lead by us and laboratory analyses on a level of productivity, qualities of grain and stability to stresses allows to conclude, that alongside with a genotype, stabilityenvironmental conditions render strong and significant influence on all complex of selection attributes.
