The variety of spring triticale adapted to the conditions of the Non-Chernozem zone of the European part of Russia was developed in cooperation with Belorussian scientists using the method of intraspecific hybridization of ecologically distant forms. The results of this variety study in the varietal tests of 2015-2020 on gray forest medium loamy and sod-podzolic sandy soils of the Vladimir region and in the Republic of Belarus are presented. The new variety had high yield of 6.06 t/ha, on average, over 7 years of variety testing on gray forest soils. Yield increase to the standard variety Normann was 0.81 t/ha or 13.3 %. An intensive type variety. In a favorable year the yield in the variety testing reached 8.71 t/ha, the increase to the standard variety was 17.1 %. A medium-ripened, medium-sized variety Slovo matured 1-3 days earlier than the standard Normann variety and the new Dobroye variety. The Slovo variety was characterized by group resistance to diseases (powdery mildew, types of rust and smut), weak susceptibility to leaf and ear septoria, stress resistance to abiotic stressors (drought resistance 8.2 points, lodging resistance 5 points). The new variety like the standard Normann variety, is intended for cultivation using technologies of various intensity levels. It can be grown on different soils according to its granulometric texture and availability of mineral nutrition elements. On sandy sod-podzolic soils, the average yield was 4.20 t/ha, that of the standard variety was 4.15 t/ha. In addition to high productivity, the new variety was characterized by high quality of feed grain, the increase in protein per hectare to the standard Norman variety was 114 kg/ha. Since 2022, the Slovo variety has been included in the State Register of Breeding Achievements Approved for Use in the Central (3) and Volga-Vyatka (4) regions of the Russian Federation. It is recommended in feed production for grain cultivation, as well as for monofodder.
