RN 29235

RN 29235 is a mid-late hybrid sunflower (Helianthus annuus L.) intended for cultivation in various regions, including the Central Chernozem, North Caucasus, Middle Volga, and Lower Volga. The plant is tall, non-branching, with large, narrowly oval, black seeds featuring gray and distinctly marked marginal stripes. The 1000-seed mass is approximately 45.5 g, and the vegetative period lasts about 126 days. The hybrid exhibits high oil content — oil content in seeds varies from 47% to 54.3%, ensuring high oil yield exceeding standard benchmarks in several regions. The RN 29235 hybrid demonstrates good resistance to major sunflower diseases, including white mold, false powdery mildew, fomoz, fomopsidiosis, and gray mold. It is also resistant to races of Sclerotinia A-F, making it a reliable choice for cultivation under various agroclimatic zones. Due to these qualities and adaptability to extensive and semi-intensive conditions in the Steppes and Southern Forest-Steppe, the hybrid shows stable high yields even under drought conditions. The recommended sowing rate ranges from 45,000 to 60,000 seeds per hectare depending on soil moisture levels. The hybrid is suitable for confectionery use, as confirmed by high kernel purity (51.1% to 59.4%) and good kernel extraction coefficient (0.83 to 0.90). Average yield in the Central Chernozem region reaches 28.2 c/ha, with maximum yields up to 42.9 c/ha, and potential yield may reach 50 c/ha under optimal conditions. High oil content and disease resistance make RN 29235 a profitable and reliable choice for farmers.
