Variety description

10 August 2026

The harvest period for the hybrid varies from 70 to 125 days. The plant is intended for planting in the period from May to August with subsequent harvesting in the autumn period.

The heads of the variety may develop unevenly and are sensitive to direct sunlight, which can cause the florets to develop a pink or yellowish tint. With excessive nitrogen fertilization in the spring period, the plant shows a tendency to cracking.
