ABSTRACT
Two catalogs of alleles of gliadin-coding loci, controlling synthesis of a storage protein of wheat caryopsis, gliadin, were compared. One catalogue comprises the alleles detected according to the electrophoretic patterns in starch gels; the other, in polyacrylamide gels. Determination of the allelic state of gliadin-coding loci in 31 previously not studied cultivars of winter common wheat allowed us to construct a matching system for the alleles compiled in the two catalogs, which gives the possibility to compare the results of wheat cultivar analyses performed at different scientific institutions.

Influence of gliadin components blocks on technological and baking grain qualities was investigated. It was shown that interaction of gliadin blocks affects on quality. The 1A4 and 1D4 blocks reduce negative action of the block 1B3 on baking quality. Combinations of gliadin components blocks of first three homeological chromosomes: 5.1.7., 10.1.4., 4.1.7., 5.1.3., 4.1.3 were the best in influence on gluten quality in Krasnodar conditions. It was managed to select lines without adverse Gld 1B3 effect. Good quality varieties: Spartanka, Skifyanka, Pobeda 50, Jirovka, Yuna, Hasarka, Verna, Ofelia, Leda, Rufa, Gorlitsa, Echo were created in the Institute. Evolutional approach, gradual development of quality traits, using of different complementary sources of quality in system of complex stepped hybridization allow to adjust "conveyor" for creation of new high-quality varieties, and gliadin markers method allow to identify them at early stages of selection.
