New early maturing soybean cultivar Zaryanitsa for conditions of Siberia

The use of new, early maturing cultivars with high productivity potential, and availability of effective herbicides have created real preconditions for the widespread introduction of soybean in the Western and Eastern Siberia. Modern cultivars should be characterized by: high and stable yields over the years in certain soil and climatic conditions of cultivation; suitability for complex mechanization of cultivation and high quality of products. Objective of the research was to evaluate a new soybean cultivar Zaryanitsa by yield and quality potential. The cultivar is included into the State Register of the Russian Federation (Patent No 9532) in 2018 in the Eastern Siberian region (11), is recommended for production in the Krasnoyarsk region. The studies we carried out in a nursery of competitive trial of the laboratory of leguminous crops breeding of the Omsk Agrarian Scientific Center from 2011 to 2019. The cultivar Zaryanitsa is early maturing (duration of the vegetative period is about 102 days), is characterized with slow growth at initial phases of development and simultaneous maturing, does not lodge and shatter, the location of the lower pods is high. These qualities make it possible to cultivate it in the harsh climatic conditions of Siberia and annually receive conditioned seeds with minimal losses during harvesting. The yield of the cultivar Zaryanitsa was noted at the standard level of the cultivar Sibirhachka (2.38 t per ha), the oil content in seeds was increased (+1.93% to st.) in average over the research period (nine years). The cultivar is characterized as stable ( < 1) of intensive type (bi > 1). In the Omsk Agrarian Research Center the cultivar Zaryanitsa is included into a scheme of crosses as a source of early maturity, stable yield, increased oil content in seeds.
