the research was carried out on the experimental basis of FSBI "Tatar research Institute of agriculture" in 2013-2015 in the field and laboratory conditions. The material for research was 93 Russian selection varieties of winter triticale from the collection of the Federal Research Center The N.I. Vavilov All-Russian Institute of Plant Genetic Resources. It is established that the winter hardiness and ear productivity are the most limiting and adaptive significant characteristics in the formation of winter triticale productivity in the conditions of Tatarstan Republic. Statistically and highly significant correlations between these indicators were revealed. In the studied 96 samples of triticale of domestic selection, winter hardiness was largely determined by the genotype (70.5%). It is shown that environmental factors played a significant role in shaping the weight of grain per ear, weight of 1000 grains and the grain nature (63.2-65.8%). The share of influence of genotype and environment on yield was almost equal (39.6 and 40.8%). Assessment of varieties on adaptive ability and stability of genotypes was carried out according to the method of Kilchevsky and Khotyleva (1985). The sources for selection of highly productive varieties on adaptive ability and stability are singled out: Kornet, Dokuchaevsky 8, Dokuchaevsky 12, Capriz, Bard, Legion, Zimogor, Consul, Vokaliz, Topaz, Kapral, SNT 13/94, Tsekad 90, Altay 4.
