New promising soybean cultivar Sibiriada
Soybean is one of the most demanded oil crops in the world farming. The aim of the research is to develop a new promising soybean cultivar. As the subject of the research we used a new perspective soybean cultivar Sibiriada, included in the State Variety Register of the Russian Federation. We conducted our studying in field small-plot experiments of the laboratory of leguminous crops breeding of “Omsk Agrarian Scientific Center” from 2015 to 2017. As the standard we used a cultivar Sibiryachka bred in “Omsk Agrarian Scientific Center”. The cultivar Sibiriada belongs to the Manchurian subspecies, is early maturing, resistant to diseases, the duration of the vegetative period - about 105 days. This cultivar is characterized by increased yield (+2.8 quintal per ha to st.) and oil content (+1.66% to st.), average protein content was equal to the standard one (40.53%) during the experiment. This causes increased nutrient yield from a unit area: ptorein - +0.81 quintal per ha to st. and oil - +0.91 quintal per ha to st. Sibiriada variety refers to stable cultivars (σd 2 < 1) of extensive type(bi < 1). The positive qualities of the Sibiriada are the combination of early maturity and increased potential of productivity and protein content, as well as the high location of the lower pods. This makes it possible to cultivate it in the harsh climatic conditions of Siberia and annually obtain conditioned seeds with minimal losses during harvesting. The cultivar is recommended for steppe and forest steppe zones of the Central, Volga-Vyatsky, Central Black Earth, Middle Volga, Ural, Western Siberian, East Siberian and Far Eastern regions.
