In 2019, the medium-early triple sunflower hybrid Bastard was passed to the State Variety Testing, and in 2020, the medium-ripe triple sunflower hybrid Bait was passed to the State Variety Testing. Newly created hybrids are resistant to the most common races of broom rape and powdery mildew, tolerant to phomopsis, white and gray rot, with a seed oil content of 49-52%, resistant to sulfonylurea herbicides. Inbred lines - sterility fixers (Od 1001 B, Od 1052 B), two hybrids (SxOd 1701 A, SxOd 1702 A - parent components), a medium-early triple hybrid Barier and two hybrids compatible with the Plant Production Institute named V.Ya. Yuriev NAAS : simple Bluetooth and triple Sudzhok were included to the State Register of Plant Varieties of Ukraine in 2020.
