Crosby

Crosby is an early-maturing hybrid of grain corn, developed jointly by the State Institution 'Institute of Grain Crops' of NAAN and LLC 'Rost Agro'. It is characterized by high yield potential and resistance to adverse conditions such as drought, heat, and cold. Plants are tall, reaching 220–250 cm in height, with strong stems resistant to lodging and breakage. Ears have a conical-cylindrical shape, 20–22 cm long, with yellow-orange kernels that are cream-colored and toothed, weighing 250–270 g per 1000 kernels. The hybrid features low pre-harvest grain moisture and high milling yield — approximately 80%.

Crosby hybrid is intended for grain, silage, and meal production, making it a versatile solution for agricultural enterprises. It exhibits a distinct Stay Green trait, enabling its use in various agronomic schemes and ensuring high harvest efficiency. The potential grain yield is 12–14 t/ha, and silage yield is 45–50 t/ha. The hybrid is resistant to high planting density and demonstrates stable grain quality, confirmed by numerous trials and competitive tests with yields up to 7.5 t/ha.

Recommended cultivation zones include the Polissia, Forest-Steppe, and Steppe regions of Ukraine, with optimal planting density ranging from 50,000 to 90,000 plants per hectare depending on the region. Crosby is highly drought-tolerant (9 points), heat-tolerant (8 points), and lodging-resistant (9 points), ensuring stable yields under diverse climatic conditions. Due to its attractive plant architecture and profitable seed production, this hybrid is among the leaders in its maturity group and is competitive with top foreign analogs.
