Variety description

10 August 2026

The hybrid belongs to the dent grain type and the medium-early maturity group with an FAO 260 rating. The plant is characterized as short, while possessing good early vigor and a pronounced Stay Green effect, which allows the leaves to remain green for longer.

The ear of the hybrid forms 14–18 rows, each containing 30–34 kernels. The variety is distinguished by high resistance to lodging, Helminthosporium, and Fusarium of the stalk and ear, and it is also characterized by rapid grain moisture loss during ripening.
