Knyazhna

KNYAZHNA is a sugar sorghum hybrid developed through sterilization-based hybridization, belonging to the sugar sorghum group. The plants reach a height of 250–270 cm, have an upright bush with weak branching, and elongated light-green leaves up to 80 cm long. The panicle is pyramidal, of medium length around 30 cm, loose, with a long neck. The grain is elliptical, light brown, with semi-glassy endosperm; 1000 seeds weigh 19.8-22.8 g. The hybrid is medium-late maturing, with average heading time, very low or absent shattering, and medium stem brittleness.

Sorghum KNYAZHNA is characterized by high drought and salt tolerance, allowing cultivation in areas with insufficient moisture, such as the North Caucasus, Volga Region, and the Far East. Despite its resistance to soil and air drought, the crop responds well to irrigation, which helps increase yield. The hybrid shows moderate damage by armyworms and low susceptibility to bacterial blight and panicle smut, enhancing its resistance to diseases and pests.

KNYAZHNA is used for grain, silage, green mass, hay, and silage production. The grain contains 70-75% starch, 12-13% protein, and 3.5% fat, making it a valuable feed resource. The potential yield of the hybrid reaches 800 centners/ha of green mass, 210 centners/ha of dry matter, and 50 centners/ha of ripe grain. The maximum green mass yield recorded in the Amur region was 213 centners/ha. Due to its morphological and biological features, KNYAZHNA is a promising hybrid for cultivation in arid conditions, ensuring stable and high yields.
