The hybrid is mid-maturing, with a vegetation period ranging from 106 to 120 days. The plant is tall, reaching a height of 160–180 cm depending on moisture availability. The hybrid is characterized by low soil fertility requirements and is suitable for classical cultivation technology on various soil types.
The sunflower possesses high tolerance to white and grey rot, phomopsis, and moderate resistance to phoma and downy mildew. Resistant to broomrape races A–E. The oil content in seeds varies from 47% to 53%. There is an increased risk of lodging with high planting density, however, the hybrid is capable of compensating for low density by increasing the size of the head and seeds.
