Abstract

The aim of the research was to create high-productivity triticale materials with use in the breeding process of spelt wheat. Materials and methods. The research was conducted during 2006–2015 under conditions of the Uman NUH. As initial material were used varieties of winter triticale Rosevskaya 6, Alcid and a sample of spelt wheat from the foothills of Carpathians. Hybridization was carried out by castration of mother flowers and forced pollination by pollen of parental form. Hybrid offspring F2-5 were analyzed for manifestation of morphological characteristics and economic-valuable traits. A systematic method of plot placement was used for control variety testing. The accounting area of the site was 10 m2 . Research results. The variety was created by method of remote hybridization of threespecies triticale and spelt, with followed individual selections in F2-4 and repeated improvement selections in F5-6 based on productivity and grain quality. In the research process, it was found that the average yield of the sample 455 during the control testing period (2012–2015) in the conditions of the Uman NUH was 4,96 t/ha. Testing of the variety took place during 2015–2018 in 17 regions of Ukraine. During this period yield capacity of the variety in Polissya area amounted to 5,03 t/ha on average, and Forest Steppe — 5,59 t/ha. According to the results of State Scientific and Technical Expertise, Strateg is listed in the State Register of Plant Varieties, suitable for distribution in Ukraine in 2018, and recommended for cultivation in Polissia and Forest-Steppe zones. Conclusions. By remote hybridization of threespecies triticale and spelt wheat variety of winter triticale Strateg was created which is listed in the State Register of Plant Varieties, suitable for distribution in Ukraine from 2018. The variety is characterized by high protein content (14.0– 14,3 %), gluten (29,8 %) and yields more than 5,0 t/ha
