Abstract
The article discusses the features of the formation of the productivity of sunflower selection Euralis in the conditions of the Southern Steppe of Ukraine. Agrometeorological conditions during the growing season of sunflower are analyzed. The morphological characteristics and quality indicators of the yield of sunflower hybrids Andromeda, Niagara, Savannah and Arcadia were investigated. It was found that the Andromeda sunflower hybrid formed the highest yield, the stability coefficient showed 2.35 and plasticity - 1.03. The hybrid adapts well to changing growing conditions, forming a consistently high yield.
