Study of Main Directions of Bread Wheat Breeding Using Protein Genetic Markers

The paper was devoted to the identification and genetic analysis of gliadin component blocks in bread wheat varieties. Compenent blocks Gld 1A5, Gld 1B1 that frequently occured in these varieties were established to be markers of high quality grain. 21 component blocks were observed in recently created varieties Gld 1A2, Gld 1A10, Gld 1B3 and Gld 1B. This clearly shows the direction of selection, which facilitates creation of varieties adaptive to biotic, abiotic factors, with high yield potential and grain quality.
