Agrobiological characteristics of varieties of spring two-rowed feed barley Gift of Siberia

The purpose of researches was creation and in-troduction in production double-row mid-season steady against drowning, diseases and a drought of a fodder grade of the summer filmy barley pos-sessing high and stable productivity with high tech-nological qualities of grain. Spring barley Gift of Siberia was created at Siberian research institute of agriculture by crossing of grades (Medikum 4369 × Medikum 4396) with subsequent individual selec-tion. It belongs to the grade medikum. The results of researches of 2011-2015 in the conditions of the southern forest-steppe of Western Siberian zone are presented in the study (Omsk Region). Three grades were studied: Gift of Siberia, Omsk 91, Sasha. The characteristic of economic and biologi-cal signs and properties of a grade Gift of Siberia is given. All advantages of this grade in comparison with a standard grade Omsk 91 and the last trans-ferred grade Sasha are shown. The maximum productivity of the grade of barley t Gift of Siberia was received in 2014, it was 6.3 t/hectare. The in-crease to Omsk 91 made 1.7 t/hectare. The grain is large, semi-extended. The grade is of medium height, mid-season. Gift of Siberia belongs to steppe ecological group of grades, it is drought-resistant and characterized by high resistance to lodging. It is also characterized by medium suscep- tibility to black and loose smut and weak stone, according to these indicators, like the variety Om- sky 91, but somewhat inferior to the grade Sasha. On average in three last years it had the mainte-nance of 13.5 % of protein in grain. The complete description of morphological features of this grade was shown. The study provides an overview of the results of studying the adaptive properties of varie- ties, which includes flexibility, stability and homeo- staticity. The calculation of parameters of stability, plasticity and homeostaticity was carried out ac-cording to S.A. Eberhart, W.A. Russell (1966), V.V. Hangildin (1977), E.D. Nettevich (1985), V.A. Dragavtsev (1984). The grade is intended for using on the fodder and food purposes. By the results of studying the grade is recommended for testing in all zones of 9, 10, 11 of regions.
