Наталья Владимировна Малицкая The effectiveness of environmental variety testing was registered by the average yield level exceeding the standard and differing in varietal and technological indicators. The tests were carried out for mass reproduction and food purposes, recommended for cultivating spring soft wheat varieties in a hillocky area of steppe plain on medium chernozem of Akmola region. The research objectives include the influence of varietal agricultural technology on the elements of the yield structure associated with the technological grain quality; grain quality conformity with the interstate consumer standards, mainly the baking ones. The objects of research include the varieties recommended for cultivation of spring soft wheat of the mid-ripening group: Akmola 2 (St), Lutestsens 90, Karabalykskaya 90, Rosinka 3, Karabalykskaya 20. Varietal cultivation technology provided an opportunity to obtain high-yielding varieties of spring soft wheat in the studied agricultural zone with noteworthy economic (length of the vegetation period, days; indicators of yield structure, yield, t/ha) and technological (bushel weight of grain, g/l; kernel hardness, %; protein content in grain, % and gluten in flour, %; falling number, sec) signs. Three varieties: Karabalykskaya 90, Rosinka 3, Lutestsens 90, have survival rate (%) at the following level: 64, 58, 66; yield (t/ha): J.85, J.92, J.98, respectively, as compared to Akmola 2 standard (60% and J.73 t/ha). The technological grain quality as to the gluten content (%) corresponded on average to grade 3 and amounted to: 24.7; 25.8; 26.0; 23.9 (standard). The above mentioned wheat varieties deserve further seed propagation in the agricultural enterprises of Akmola region (Kazakhstan).
