Variety description

10 August 2026

The hybrid belongs to the early-maturing category. Early harvesting is possible when using plastic covers. The variety is responsive to intensive cultivation technologies and adapts to the conditions of different regions.

Cobs reach a length of 20–21 cm and have well-developed kernels, including those at the cob tip. The kernel is small and characterized by high sugar content. In comparative trials, the hybrid remains competitive in terms of grain quality, despite potential trade-offs in total marketable cob yield.
