Abstract
The paper highlights the results of agroecological experiments on 11 varieties of winter triticale. The experiments were conducted in the steppe climate zone of thePrimorskTerritoryin 2017-2018. The research aims at identifying the best varieties of fodder and grain forage, which are characterized by high productivity of green mass and grain with valuable economic features. Extreme weather conditions observed during the research period contributed to exploration of the crop response to bad environmental factors. Winter triticale winterhardiness was 0.3-2.1 points on average for varieties. The green mass decreased by 69% due to freezing. The researchers observed the highest prospective green mass yield (28.6-35.7 t/ha) in the following varieties: Tyumenskaya zernokormovaya, Zimogor, Kornet, which significantly exceeded the winter rye Spasskaya mestnaya productivity by 6.3-13.4 t/ha. The crop yield of these varieties was stable and changed insignificantly by 2.6-3.4 t/ha. The experiment revealed Agraf and Tornado varieties that contributed to the highest yield of digestible protein - 5.9 c/ha and available energy - 69.3-66.7 GJ/ha, exceeding the indicators of winter rye by 2 c/ha and 16.6-19.2 GJ/ ha. The authors claim the prospective variety is Tyumenskaya zernokormovaya, which had the highest yield of dry substance and available energy - 7.5 t / ha and 85.5 GJ / ha. These parameters were higher than those of the standard grain and productivity was by 0.5 tons / ha higher. This variety can compete with winter rye for fodder purposes. The winter triticale is a crop for risky cultivation in this climate zone. It can grow in the areas with high snow cover.
