The hybrid corn 'Berta' is an early-maturing three-line variety with a vegetative period of approximately 99-131 days, belonging to FAO group 150. It was developed by Kazakh and Russian breeders and recommended for cultivation across a wide range of regions in Russia, including the Northwestern, Central, Volga-Vyatka, North Caucasus, Middle Volga, Lower Volga, Ural, West Siberian, East Siberian, and Far Eastern regions. The hybrid is characterized by high grain yield, reaching over 100 centners per hectare, confirmed by state variety trials, where it surpassed standard hybrids in productivity and resistance. 'Berta' features semi-pear-shaped yellow kernels with a 1000-kernel weight of approximately 330-332 g. Plants reach a height of 210-250 cm, with ears positioned at 70-85 cm. The hybrid is resistant to lodging, dusty head smut, ear diseases, and damage from corn stalk borer, and shows moderate resistance to bubble head smut. Due to its cold tolerance and suitability for early planting, the variety is appropriate for cultivation under various climatic conditions, including dry and fallow lands. It is a versatile hybrid suitable for both grain and silage production. The optimal planting density is 60-65 thousand plants per hectare for dry conditions and 70-75 thousand for irrigated fields. In southern regions, 'Berta' can produce a second grain harvest on irrigated plots, making it a profitable choice for intensive farming. High productivity and adaptability ensure stable, high-quality yields across various agroclimatic zones.
