Until recently, in the Oryol region late varieties of sunflowers were grown and used for feeding purposes in the flowering stage to harvest for silage and herbage. With the creation of new early sunflower varieties and hybrids it became possible to cultivate sunflower for seeds in the region. The purpose of the study is to establish the adaptability of sunflower varieties to determine the area of distribution, to identify and recommend the best high-yielding varieties of sunflower. During the study (2012-2014) there were conducted phenological observations, measurement of crop density, and dynamics of accumulation of biomass of sunflower hybrids. The evaluation of grain quality was based on physical parameters. The highest oil content in the years of research was found for varieties: Belgorod 94 – 6.2-50.5%; Bogucharets – 47.8-49.7%. Oil harvest from the varieties studied was 0.28-0.47 t/ha. It was proved that in the extreme weather conditions of the growing season of 2014, the varieties tested showed adaptive stability and high productivity.
