ROKER is a mid-early sorghum x sudangrass hybrid (Sorghum x drummondii) intended for cultivation in the Volga Region. The plant is characterized by an erect, highly branched bush with long leaves of medium width and a white midrib. The stem is long with an intermediate pith, and the panicle is symmetrical and erect. Seeds are elliptical, reddish-brown in color, with a 1000-seed mass ranging from 17.7 to 19.8 grams. Flowering occurs later, and the glume scales turn brown-black upon ripening. Average dry matter yield in the region reaches 57.9 centners per hectare, exceeding the standard average by 3.5 centners.
The ROKER hybrid is distinguished by high resistance to drought and lodging, as well as resistance to pests such as aphids, bunt, and bacterial blight. The plant has dark green lanceolate leaves and a large erect panicle 25-27 cm long, gray-white in color. The grain is round, matte white, glassy, film-free, threshes well, and has a grain yield of up to 85%. The vegetative period is 100-105 days, which allows the hybrid to be used for both grain production and silage.
ROKER is suitable for cultivation in arid climatic conditions due to its high drought resistance and disease resistance. It is used as a fodder crop for livestock, as well as for grain production. Due to its agronomic characteristics and stable yield, this hybrid is a reliable choice for farmers seeking high-quality and high-yielding sorghum crops.
