New varieties of spring oats Otrada and Foma have been created in the Northern Trans-Ural Agricultural Research Institute. Midseason varieties are resistant to drowning and shedding, and mid resistant to spring-and-summer drought, have potential productivity of 7,0-8,0 t/ha. The top grain yield of the variety Otrada was received in 2013 on the Barachatsky state seed-trial ground of the Kemerovo region (7,63 t/ha). The top grain yield of the variety Foma was received in 2014 on the Nerchinsk state seed-trial ground (Trans-Baikal Territory)-8,27 t/ha. Those varieties had rather high grain yield (Kz. = 37,4-38,7). They formed high quality grain (grain-unit up to 518,5-548,0 g/l, thousand-kernel weight is up to 37,4-42,1 g, grain hoodness is 23,6-24,7%). The varieties can be used as forage as well as food. The varieties are listed on the National registry of selection achievements. The variety Otrada has been included in the registry since 2013 and recommended for cultivating forage in 9 regions of Ural, 10 regions of Western Siberia and 12 regions of the Far East of Russia. The variety Foma has been included the registry since 2015 to cultivate for feed and food purposes in 10 regions of Western Siberia, 11 regions of Eastern Siberia and 12 regions of the Far East of Russia.

The studies of plants’ assimilation activity of the Triticum carthlicum Nevski. (=Triticum persicum Vav.) tetraploid species’ variety samples have been carried out in the subtaiga zone (Aromashevo) and the northern forest-steppe zone (Tyumen). The number of leaves on plants by zones varied from three to five. Measurements showed that the lamina length varied from 6.4-23.7% in the northern forest-steppe zone and from 0 to 21.9% in Aromashevo. The lamina area on the main shoot of the Triticum carthlicum Nevski variety samples in the northern forest-steppe zone amounted to 62.3 cm2, which was 26 cm2 less than in the subtaiga zone. Calculation of net photosynthetic productivity in northern forest-steppe zone showed that Triticum carthlicum Nevski variety samples formed from 10.864g*m2/day to 20.764 g*m2/day, giving way to durum and soft wheat. In the subtaiga zone, PPn of Triticum carthlicum Nevski wheat varied from 9.088 to 13.827 g*m2/day, significantly yielding Bezenchukskaya 139 variety.
