Change of biotype composition of spring tricticale varieties in the process of cultivation

The research objective was studying by method of electrophoresis of prolamin the change of biotype struc-ture of summer triticale varieties in the course of cultiva-tion in the conditions of Tyumen Region. As the material for research individual kernels of spring triticale varieties Ulyana and Solovei Kharkovsky, cultivated on experi- mental field of Northern Trans-Urals SAU served. As a result of electrophoretic separation of prolamines, it was established that both varieties were heterogeneous in gliadin component composition. In the spectra of the variety Ulyana, 14 types of spectrum were found, and the varieties Solovei Kharkovsky - 5. When comparing obtained electrophoretograms with the standard spectra of varieties, it was established that 4 of detected types of the spectrum of the variety Solovey Kharkovsky and 12 of the variety Ulyana were not typical for them. The amount of impurity was from 27 % in the variety Ulyana to 36 % in the variety Solovei Kharkovsky...
