Sunflower PR64A78 is a high-yielding hybrid with a vegetation period of 110 to 122 days, classified as mid-early maturity. Plants reach an average height of about 160-165 cm and are characterized by rapid growth in early development stages, as well as a well-developed root system and strong stem. The hybrid exhibits high plasticity and is adapted to various soil-climate conditions, allowing successful cultivation in the Forest-Steppe and Steppe zones of Ukraine.
One of the key features of PR64A78 is its high drought resistance and resistance to stress factors, including resistance to lodging and diseases such as phomopsis, phomopsis, and false powdery mildew. The hybrid also shows resistance to five races of the sunflower nematode, significantly reducing the risk of yield loss. The 1000-seed mass is approximately 59 grams, and the oil content in seeds reaches 48.8-50%, ensuring a high oil yield per hectare — up to 1241 kg.
PR64A78 has good sowing qualities and high germination energy, promoting uniform and rapid emergence. It is recommended to avoid planting on fields infested with races of the sunflower nematode not included in the hybrid's resistance spectrum. Due to its characteristics, this sunflower is a reliable choice for agricultural producers seeking a stable and high yield of oilseed crop with excellent oil quality.
