A simple sunflower hybrid Typhoon was received by the method of interlinear hybridization with an evaluation of a set of agronomic traits. It has a complex resistance to the main pathogens and stressors. It is resistant to broomrape (races A-E), and to a complex of downy mildew races. It is highly tolerant to phomopsis. It is responsive to the traditional cultivation technology. The hybrid Typhoon is of moderately intense type characterized by uniformity in flowering and ripening, and by resistance to plant lodging. The plants height is 170-190 cm, the head is large, convex with optimum angle. Oil content of seeds is 49.0-52.0%. Thousand-seed weight is 51-64 g. It is equal to the best world varieties in regards to the productivity and oil yield per area unit. The maternal form of the hybrid is line VK 101. Oil content of seeds is 43.0-45.0 %. Thousand-seed weight is 54-58 g. The plants height is 125-135 cm. Head diameter is 16-18 cm. The paternal form is pollen fertility restorer, middle-early multiple-headed line VK 303 with a high combining ability. The emergence-flowering period is 54-56 days. It is resistant to the most widespread races of downy mildew in the Northern Caucasus region. In the Krasnodar conditions, during the 5-year trials, the average yield of the hybrid Typhoon was 3.78 t per ha. The maximum yield was received at the Don experimental station of VNIIMK in 2015 and 2016 (3.59 and 3.96 t per ha, respectively). Since 2018, the sunflower hybrid Typhoon is included in the State Register of Breeding Achievements of the Russian Federation, approved for production in the Central Black Earth and Northern Caucasus regions. The hybrid originator is VNIIMK.
