In the last decade, Ural and Siberian breeders have created a series of valuable and strong varieties of spring soft wheat, which have mainly successfully passed the State Variety Testing and are included in the Register of breeding achievements in 10 regions. These include the Irene variety, which is sown not only in Western Siberia, but also in Eastern Siberia and other regions of the country. It is well adapted to the conditions of the Tyumen region. The variety has been grown here for 13 years, but the variety technology has not yet been fully developed. It is cultivated according to generally accepted technology. Taking into account the current situation with the variety, we are conducting research on the development of elements of varietal technology. The article analyzes the results of the impact of mineral nutrition levels on the yield and quality of grain of spring soft wheat variety Irene in KRiMM Uporvo district of Tyumen region. Over the years of research (2016–2018), it was established that the leached black soil in the control version without mineral fertilizers yielded 2.57 t/ha of early maturing Irene variety. The variety reacts positively to the application of mineral fertilizers up to the yield level of 5 t/ha. At the same time, the yield is combined with the quality of grain. Profitability of application of mineral fertilizers for the yield of 4 and 5 tons per hectare was 130.7 and 139.5 %, respectively. In the control version it was 61.3 %. Irene variety is well adapted to the conditions of the Tyumen region, it is necessary to continue the study of other elements of the variety.

In the Siberian District, including the Tyumen region, a great contribution into production of foodgrain has been made by valuable and strong varieties of spring soft wheat Iren, Omskaya 36, Novosibirskaya 31. It should be noted that elements of cultivation technology of these varieties for seeds have been developed insufficiently. In the article, the 2016-2018 data have been analyzed according to the productivity and quality of seeds of the chosen wheat varieties in dependence to the level of mineral nutrition (for planned productivity of 4.5 and 6 t/ha). It has been established that in the conditions of the northern forest-steppe of the Tyumen region the level of mineral nutrition for productivity of 4-5 t/ha provided high quality of seeds. In the variant with NPK of 4 t/ha the yield of seeds of the general productivity was 73.0-77.8%, the mass of 1000 grains – 33.9-38.5, the protein content – 15.3-16.8%, the energy of germination – 58.0-67.3%, the laboratory viability – 94.3-96.5%. The main part of seeds (67-74%) sprouted in 5-6 seminal roots and when resowing in 2017-2018 it gave dense, strong shoots. Seeds from the chosen variant had advantage before the control without fertilizers and before variants with higher level of mineral nutrition in many quality indicators. It has been established that germination energy of seeds closely correlated with protein content (r = 0.72…0.82) and insignificantly – with the mass of 1000 grains (r = 0.27…0.28). Between productivity and energy of germination of seeds the correlation was negative(r = -0,32…-0,40)
