ZERNOGRADESKY 299 MV

Zernogradsky 299 MV — medium-early complex four-row hybrid corn, intended for grain production. Plants reach a height of 220-240 cm, with 11-12 above-ground nodes and 16-17 leaves. The ear is cylindrical, forming at a height of about 80 cm, up to 22 cm long and weighing about 280 g, with 16 rows of kernels. Kernels are dent-shaped, yellow, with a 1000-kernel weight of about 290 g and protein content of 9.0%. Grain yield is approximately 79.3%. Vegetation period varies depending on the cultivation zone: 110 days in the steppe zone to 131 days in Polесье. Grain moisture at maturity ranges from 23.9% to 30.6%. The hybrid is characterized by high yield and resistance to adverse conditions. Average grain yield in various trials reached 58.6-81.7 ц/га, exceeding national standards. Drought resistance is good, and cold resistance is rated high (4.7 points). It is tolerant to stalk rot, ear smut, and bubble rust, but susceptible to ear bacterial blight and fusarium. Damage by stalk borer is significant, reaching 78-88%, while damage by corn borer is at standard levels. Seed production is conducted on a sterile basis with full fertility restoration. Zernogradsky 299 MV is recommended for cultivation in the forest-steppe soil-climate zone of Ukraine. The hybrid features good plant uniformity in height and simultaneous development of growth phases, facilitating agronomic practices. Due to its high yield and resistance to major diseases and pests, this hybrid is a reliable choice for obtaining quality grain.
