“…The study of spring triticale in 2012-2016 was conducted in the south of the Amur region at the State Variety Testing Station (SVTS), Kozmodemyanovka village, in the central part at the Svobodnensky State Variety Testing Station , Nizhnie Buzuli village, and in the northat the Mazanovsky State Variety Testing Station, Beloyarovo village. The soil in the southern zone is meadow-chernozem-like [15]. It has humus of 3 -6%, mobile phosphorus P2O5 -84 mg/kg of soil, exchangeable potassium -235 mg/kg of soil.…”

The need for research is due to the growing demands of the region's animal husbandry in fodder grain. The goal is to establish the average and maximum values of the main economic indicators of triticale varieties in various zones of the region. The experiments were carried out in 2012–2016 on the fields of the zonal State Variety Testing Stations of the Amur Region. Soils are typical of zones. Meteorological conditions during the growing season of triticale are different. Triticale varieties were studied: Karmen St, Grebeshok, Rovnya, Ukro and Yarilo. Late-ripening varieties in all zones of the region form a high stem. Location of triticale varieties by grain threshing Karmen> Rovnya> Grebeshok and Yarilo> Ukro. The largest mass of 1000 grains - 53.6 g and a yield of 5.36 t/ha is formed by the Karmen variety in the south of the region. Yarilo gives the highest yield in the central zone, and Rovnya in the northern zone. The increase in yield of Yarilo and Rovnya varieties compared to the control ranged from 0.13 to 0.16 t/ha, or from 4.2 to 5.2%. The smallest significant difference in yield for varieties was 5.4–15.8%. In the central zone of the region, the Yarilo variety significantly exceeds the standard by 0.69 t/ha, or 28.3%, in the north, the Grebeshok and Ukro varieties are significantly inferior to the standard by 0.16 and 0.33 t/ha, or 5.6 and 11.5%. The genetic series of the yield potential of varieties in the area of Karmen> Yarilo> Rovnya>Grebeshok > Ukro. A model of factors determining the adaptive potential of triticale in the Amur region is proposed.

Abstract. In the Amur region the share of soybean in the structure of sown areas has reached 73.7 % over the last decade, the phytosanitary condition of agrocenoses has deteriorated, pesticide load on fields has significantly increased, which causes new ecological risks. Some reduction of this load may be caused by increasing the proportion of grain crops, including triticale. The purpose of the study was to establish the effective sowing date of spring triticale varieties providing optimal photosynthetic activity of agrocenoses in the conditions of Amur region. The method of field experiment by B. A. Dospekhov and determination of photosynthetic activity of crops by A. A. Nichyparovich were used. Scientific novelty. The photosynthetic activity of spring triticale varieties at different sowing dates in years with different meteorological conditions has been evaluated. Results. The greatest area of leaf apparatus is formed at sowing in April, 29 reaching maximum values in a phase of flowering in sort Ukro – 37,2 thousand m2/ha, in sort Yarilo – 30,4 thousand m2/ha, in sort Karmen – 33,0 thousand m2/ha. The correlation analysis revealed direct and strong influence of sowing dates on formation of the assimilative apparatus of plants and yield of spring triticale rxy = 0,833. Statistically significant differences were obtained p = 0.016. In the regression equation with increasing leaf area by 1 m2/ha the grain yield of triticale is expected to increase by 0.056 t/ha. Photosynthetic potential of the varieties differed in the years of research and depended on the value of the assimilating surface and the duration of the leaves. A regular decrease in net photosynthetic productivity from early to late sowing was established. The highest value of net photosynthetic productivity was obtained at sowing 15.04 – 2.03 g/m2 per day. The constituent elements of photosynthesis resulted in grain yields of the variety Yarilo – 2.26 t/ha, Ukro – 2.61 t/ha and Karmen – 2.23 t/ha.
