VARIETY TESTING OF SPRING BARLEY IN THE CONDITIONS OF THE NORTH-EAST OF KAZAKHSTAN
Аннотация
The article presents the results of research in 2014-2016 by Pavlodar Agricultural Enterprise LLP. 20 breeding lines of barley on chestnut sandy loam soils of northeastern Kazakhstan were studied. The aim of the work was to identify the most productive and locally resistant varieties capable of providing a stable harvest in a variety of soil and climatic zones of the region. The meteorological conditions of the growing seasons were characterized by significant contrast, which made it possible to assess the adaptive abilities of the lines to various environmental stress factors. According to the research results, six promising lines with a growing season of 78-81 days, a plant height of 62-67 cm and a mass of 1000 grains of 53.5–56.0 g were identified. The content of crude protein in the grain was 17.6–19.6%, fiber — 3.36–4.46%. The average yield over three years ranged from 20.0 to 21.7 c/ha, which exceeds the standard by 1.8–3.5 c/ha. Lines 49/99-11 and 31/44-72 showed the greatest increase in yield to the standard (+3.2 and +3.5 c/ha, respectively). The line 31/44-72, which has high economically valuable characteristics, is recommended for transfer to the State variety testing and introduction into production. Thus, the conducted research contributes to improving the efficiency of barley breeding in the region, providing agricultural production with new highly productive varieties adapted to local conditions.
