The aim of the research was to conduct basic screening of new lines and cultivars of winter hexaploid triticale by the technological and molecular genetics indicators. Molecular and genetic research conducted by polymerase chain reaction allelic variants of gene loci Wx-A1, Wx-B1, and quality parameters of grain, flour and bread – on technological markers. The new cultivars and lines of winter hexaploid triticale of Nosivka Breeding and Research Station of Remeslo Myronivka Institute of Wheat by technological indicators of grain, flour and bread quality were studied. According to representative criteria’s the most promising genotypes, which are the main products in terms Forest-Steppe ecotypes’ and a high-quality raw materials for bakeries and bioethanol were identified. Molecular and genetic identifications of allelic variants of genes loci Wx-A1, Wx-B1 triticale, which in the early stages of ontogenesis to predict targeted uses genotypes were conducted. The first among a series of triticale cultivars and lines Forest-Steppe ecotypes and biotypes with nonfunctional b gene allele WxA1, which defines a high content of amylopectin of starch, an important release for more ethanol was identified. It was found that technological characteristics of grain, flour and bread of new cultivars and lines of winter triticale meet the modern requirements production dietetic food and bioenergy products is important and relevant in the context of food security of Ukraine.
