title: ECOLOGICAL TRIAL OF SUNFLOWER HYBRIDS OF RUSSIAN AND FOREIGN BREEDING IN CRIMEA
abstract: Sunflower hybrids of the Russian breeding were tested in ecological trial in the experimental plot of the Research Institute of Agriculture of Crimea in 2017–2020. There were estimated their general economically valuable traits. The following hybrids had the highest yield of seeds in average in the research years: Signal – 1.22 t/ha (increase to the control hybrid Prestige is 0.09 t/ha), Garant and Sprint – 1.18 t/ha (increase to the control – 0.04 t/hа). The highest oil content in seeds in year
