Triticale is the high-yielding grain crop, resistant to the complex of the abiotical and biotic environmental factors, which combines biological fullmouthed of the rye protein complex with uniquely wheat backing properties. The aim of these researches is to make the comparative analysis of forming the productive qualities of spring triticale and spring wheat in the Middle Priamurye conditions. The grain quality is provided by a number of features, which determined by hereditary factors and a complex of edaphoclimatic factors and agrotechnical conditions. Some grain quality features of the spring triticale and wheat vary with different limits depending on the genotype and environmental conditions. Sort of the spring triticale Ukro and divided into districts sort of the spring soft wheat Khabarovchanka are the object of researches. In fact their productivity potential realizes in like manner – 1,4-3,3 t/ha in the Middle Priamurye conditions. In vegetation period providing with warmth renders the most influence on forming  the qualitative and  technological features of these cultures. Moreover, need in warmth and moisture is diametrically opposite of spring wheat and spring triticale. The spring triticale sort Ukro excels the spring wheat sort Khabarovchanka by mass of 1000 grains, output of meal of the first sort, relation of  elasticity to tensility and gluten quality. The accumulation of lysine in spring triticale protein is more on 160 mg/% than in protein of spring wheat. Technological indexes of grain quality testifies to suitableness and perspectivity of triticale meal use in baking of bread industry.

Aim. In regions where farming is risky it is especially important to grow crops with high productivity and optimal adaptability to environmental stress factors. In this regard, the purpose of this study was to determine the environmental sustainability of spring triticale cultivars to the unfavourable environmental factors of the Middle Amur Region.Material and Methods. Many statistical and mathematical methods were used to determine the adaptiveness of potential spring triticale cultivars by yield. As re‐search material, we used 40 cultivars and breeding lines of spring triticale of various ecological and geographical origins.Results. Using cluster analysis, triticale samples were ranked into 5 groups with differing responses to the spectrum of changes in environmental conditions. As a result of this research, it was established that the Skoryi (Russia) and Viktoria (Ukraine) cultivars achieve maximum yield potential as well as having an ability to neutralize the negative impact of soil and climatic factors.Conclusion. The reaction of triticale cultivars to specific vegetation conditions was established. Exemplars of spring triticale with high environmental sustainability, ductility and stability for economic use and further breeding were identified.
