Riga, Latvia: Baltija Publishing. 220 pages.978-9934-588-11-2http://lib.udau.edu.ua/handle/123456789/7295According to scientists, the competent selection of a hybrid provides 35% of the yield, the rest – agrotechnological and soil-climatic factors. Preference should be given to drought-resistant hybrids, resistant to lodging and shattering, high-oil hybrids, adapted to the continental climate.The research program was designed to establish resistance of lines and hybrids to the sunflower sobole (Orobanche cumana Wallr.). To find decisions during 2017-2018 field experiments were carried out, they were carried out in the household of SGI-NTNS «Dachna» of Biliayivskyi district of Odesa region.en-USSunflowerhybridsseedsagrotechnologicalІнше
