Variety description

10 August 2026

The hybrid belongs to the mid-season maturity group with an FAO 380 rating. It is mentioned in variety registers as a breeding product, but it is currently an obsolete entry and is practically absent from modern commercial offers.

Detailed morphological descriptions, such as plant height or lodging resistance, are unavailable in open sources. In scientific papers, the hybrid was mentioned exclusively in the context of phenological studies on ear development and flowering dates.
