Creation and breeding value of introgressive forms, obtained by hybridizations of Triticum Spelta L. × Triticum turgidum subsp. dicoccum (Schrank ex Schübl.) Thell.

The aim of the research was to expand genetic diversity spelt wheat by introgression material species Triticum turgidum subsp. dicoccum (Schrank ex Schübl.) Thell. and create on this basis new source material. Materials methods. study conducted during 2016–2022 in conditions Uman National University Horticulture, located zone Right-Bank Forest-Steppe Ukraine, subzone unstable moisture. winter variety Zoria Ukrainy (maternal form) sample (pollinator). used common technology growing cereals. Sowing carried out optimal time for – third decade September. All records observations were performed accordance with generally accepted In work a systematic method plot placement four repetitions. Results. As result researches number introgressive lines spelled different level manifestation morphological economically valuable features created. created samples according morphology ear are divided into morphotypes spelt, emmer intermediate forms. Conclusions. creation initial breeding at distant hybridization spelta L. × var. dicoccoides. Valuable high-yielding obtained using breeding. It found that highest frequency transgression second generations recor­ded weight grain from (19.1–20.0%). yield (535.2 g/m2) 1000 grains (44.8 g) significantly exceeded standard (sample 230), as well protein (20.4%) gluten (44.0%) 227). selected will be donors genes econo­mically traits schemes wheat.
