T 1333 XF is a high-yielding, three-line hybrid sunflower of early-maturing type with a vegetation period of 90–100 days. It is recommended for cultivation in the Polissian, steppe, and forest-steppe zones, making it a versatile choice for various climatic conditions. Plants of this hybrid have a medium height of 200–220 cm, a strong stem resistant to lodging, and a well-developed, robust root system, ensuring good adaptation and stable yield even under drought conditions. The height of the flower heads is 60–65 cm, and leafiness reaches 14 leaves, which promotes efficient photosynthesis and plant development. Morphobiological characteristics of the hybrid include conical heads 20–22 cm long with 14–16 rows of seeds, each row containing 35–40 seeds. Seeds have an orange-red color and toothed shape, with a thousand-seed weight of 260–280 g. Due to these parameters, the hybrid demonstrates high yield potential of 11.5–12.5 tons per hectare. Moreover, T 1333 XF exhibits good water use efficiency during the ripening stage, ensuring a dry and high-quality harvest with excellent consumer properties. The hybrid shows resistance to drought periods, pests, and diseases, and does not shed foliage, facilitating harvesting and improving seed material quality. It positively responds to agronomic practices such as fertilizer application and chemical treatment, which contribute to soil fertility enhancement and increased yield. The recommended plant density varies by region: 55–60 thousand plants per hectare in steppe zones, 65–75 thousand in forest-steppe zones, and 75–90 thousand in Polissia. The main use of the hybrid is for seed production.
