Sunflower varieties selection with high oil content

The article presents the results of long-term research on the creation of high oil and large-fruited sunflower varieties for use in 5 (Central Chernozem) and 7 (middle Volga) regions. Increasing the yield of sunflower oil seeds and improving their quality largely depends on targeted breeding work. Agricultural production needs highly productive precocious and early maturing varieties that are adaptable to local agroecological conditions and tolerant to the main common pathogens. Agroclimatic conditions of the region do not allow growing foreign-selected sunflower hybrids here, as they do not reach economic maturation (full ripeness). Breeders created a new high-oil (53.3%) variety of sunflower Chakinsky 100 with a yield potential of up to 50 centner per hectare in the Tambov research Institute (a branch of the I. V. Michurin Federal Research Center). The variety is included in the state register of breeding achievements in 2018 (patent no. 9648).
