Maize P 0023

P 0023 — a mid-late maturing hybrid of maize (Zea mays L.), intended for grain production. It is included in the State Register for the North Caucasus region and is characterized by good tolerance to stressful conditions, especially during critical flowering and grain-filling stages. Plants have medium height and broad leaves, with a dent type kernel featuring yellow coloring at both the upper and lower parts. The vegetation period is approximately 113 days, slightly shorter than the standard, allowing the hybrid to successfully adapt to local climatic conditions. The hybrid exhibits high drought tolerance and lodging resistance, ensuring stable yields even under adverse weather conditions. Average grain yield in the region reaches 65.4 c/ha, with a maximum of 103.0 c/ha, exceeding the standard level by 9.2%. Grain moisture at harvest is approximately 21.4%, lower than the standard, facilitating subsequent processing and storage. The ear has medium length and diameter, with a short stalk and average number of rows, as well as a slightly conical shape, making this hybrid suitable for mechanized harvesting. Morphological features include anthocyanin pigmentation of the ear stalk, weak leaf sheath and root pigmentation, and medium spikelet density. These characteristics indicate the plant’s genetic stability and adaptability. The hybrid is suitable for cultivation in the North Caucasus region and may be recommended for obtaining high-quality grain with good yield potential.
