The selection of parental pairs is carried out considering their genealogical trees and the dynamics of the lim factors of the environment, in the creation area, with further hybridization, and subsequent multiple re-sowing of the population. The Kazakhstanskaya rannespelaya variety was created by selection from the F5 hybrid combination of Novosibirskaya 67 × Omskaya 9, the Interdepartmental program DIAS. The breeding record of Novosibirskaya 67 consists of 9 and Omskaya 9 – of 37 varieties, of which 19 are of winter origin. The inheritance of ear productivity, in both varieties, followed the type of complementary epistasis, with incomplete dominance and overdominance, with a large proportion, of recessive genes. In conditions of the Northern Trans-Urals, an early-ripening, yielding line was selected in F5 - Lutescens 1227-8-79, which became the ancestor of the Kazakhstanskaya rannespelaya variety. The variety has successfully passed the State variety testing and is registered in the Qostanay, North Kazakhstan and Kokchetav regions of Kazakhstan, and in the Chelyabinsk region of the Russian Federation, according to the grain quality it is included in the list of strong varieties. In the north of Kazakhstan, Kazakhstanskaya rannespelaya is cultivated on large areas. This variety, as a genetic source, has a good variety-forming ability. With its participation, 6 varieties were created in the Research Institute of the Northern Trans-Urals. Of these, Tyumenskaya 29 and Grenada are registered in 9 and 10 zones of the Russian Federation. It is used in the breeding programs of the Republic of Kazakhstan.
