PR63A90 sunflower hybrid is an early-maturing crop with a maturation period of up to 110 days. The plant is tall, reaching a maximum height of 170 cm, with a strong stem and well-developed root system, providing resistance to lodging. The head is large, convex, with a diameter of about 18 cm, oriented downward. Seeds are medium-sized, oval-shaped, black, without stripes, and have a high oil content — 48-49% — making the hybrid high-oil and attractive for professional cultivation. PR63A90 exhibits high tolerance to various stress factors and diseases. The hybrid is resistant to false powdery mildew, Phomopsis, Sclerotinia, as well as white and gray rot, significantly reducing the risk of yield loss. The crop has good plasticity and adaptability, allowing successful cultivation in various soil-climate conditions, including regions with a higher risk of Phomopsis infection. The absence of branching and moderate hairiness on the upper part of the stem contribute to optimal plant development and stable yield. PR63A90 sunflower is suitable for professional use, offered in 50-gram packaging, and belongs to the mini-profi series. Due to its self-pollinating nature and drought resistance, the hybrid demonstrates stable yield performance regardless of climate zone or soil type. These characteristics make PR63A90 a reliable choice for farmers aiming to achieve high-quality sunflower yields.
