Derrick corn hybrid is a mid-early maturity hybrid with FAO 230, included in the State Register for the Central Black Earth Region. The plant is tall, with a small to medium angle between the main ear axis and side branches, which are slightly curved. Silk emergence is early, with very weak anthocyanin pigmentation. The ear is of medium length, with semi-toothed kernels, yellow in the upper part and medium intensity of stem coloration. The hybrid has a medium grain yield of 51.1 centners per hectare, which exceeds the standard, and a standardized dry matter content of 91.2 centners per hectare, meeting the standard level. Derrick is resistant to common smut but susceptible to ear fusarium and suffers moderate damage from stalk borers.
Additionally, there is a double-cross hybrid DKC 4391, classified as mid-early maturity with FAO 350, included in the State Register for the North Caucasus and Lower Volga regions. The plant is medium to tall, with strong anthocyanin pigmentation of the first leaf sheath and weak or absent pigmentation of the glumes and anthers. Silk emergence is medium-late. The ear is weakly conical, thick, and long, with a short stalk. The kernels are toothed, with yellow upper part and yellow-orange lower part, strong stem coloration intensity. Grain yield in the North Caucasus region reaches an average of 56.1 centners per hectare, and in the Lower Volga region — 55.8 centners per hectare, exceeding the standards. Grain moisture at harvest ranges from 18.2% to 20.9%, and the vegetative period is from 103 to 110 days. Recommended planting density varies by moisture zone and ranges from 55 to 75 thousand plants per hectare. The hybrid is suitable for conventional, minimal, and no-till soil cultivation.
The producer of the DKC 4391 hybrid is the company MAISADOUR SEMENCES S.A., and the originator is MONSANTO TECHNOLOGY LLC. These corn hybrids are characterized by high productivity and adaptability to various climatic conditions, making them popular for cultivation in different regions of Russia.
