The experiments were carried out in the period of 2015 to 2020 at the Far Eastern Research Institute of Agriculture (Khabarovsk Krai). Over the years of research the yield of collection samples of spring-planted triticale was on average 2.3-3.3 t/ha. According to the grain yield, the samples of AC Certa, Lana, Dagvo, Zolotoy grebeshok, Ulyana, Uzor, Lotos, Mykola, Victoria, Rovnya, Sandio, which exceed the standard variety Ukro by 0.2-0.7 t/ha were distinguished. The grain protein content varied significantly over the years – from 11.1 to 18.1 % with an experiment average value of 14.1 %. The samples of AC Certa, Dagvo, Skoriy, Zolotoy grebeshok with a high grain protein content of 14.7-15.5 %, exceeding the standard variety Ukro by 0.1–0.7 % were noted. On average, over the years of research, the lysine content of samples Dagvo, Kobzar, Losinovske, Sandio exceeded the standard variety Ukro by 100–139 mg/% and amounted to 500–539 mg/%. The correlation coefficients between the yield, the protein and lysine content in the grain of the collection samples of spring triticale and the hydrothermal index for the period from April to August were calculated. High positive values of the correlation coefficients (r=0.93–0.99) indicate a significant influence of the combination of meteorological environmental factors on the formation of yield and grain quality of spring triticale in the conditions of the Middle Amur region.
