The characteristic of yield and seed quality of a new promising soybean cultivar Sibiryachka in the southern forest-steppe of the Western Siberia

The characteristic of yield and basic seed quality traits of a new promising soybean cultivar Sibiryachka developed at the Federal State Budgetary Scientific Institution “Siberian Research Institute of Agriculture” (SibNIISKh). The researches were conducted under the conditions of the southern forest-steppe of the Western Siberia in the 2001-2015. This cultivar belongs to the Manchurian subtype and the Ukraiinika approbation group. The cultivar is early (the average vegetative period was 97 days). Both the protein formation in soybean seeds and crude fat content (a percentage of a year input was 82.9%) was mostly influenced by the growing conditions - 58.5% with a large percentage of the genotype influence (39.1%). The cultivar Sibiryachka is stable under changing environmental conditions both on protein and crude fat contents in seeds (bi = 0.94-0.97). And contrary, on yield this cultivar is responsive to the growing conditions (bi = 1.20). Accordingly, improved cultivation conditions will increase the yield, and as a consequence, increase the protein and crude fat yield per an area unit. Since 2013 the soybean cultivar Sibiryachka has been included in the State Register of breeding achievements (Author’s Certificate No. 55962 of 04.23.2013; Breeding Invention Patent No. 6897 of 04.23.2013). Since 2015 the cultivar Sibiryachka became the main standard in the State Variety Testing for the Omsk Region and in the breeding nurseries of the FGBNU SibNIISKh. The cultivar is widely cultivated in the steppe and forest-steppe areas of the Western and Eastern Siberia and the Urals.
