Variety description

10 August 2026

The variety, also known by the breeding number PV-1800, belongs to the semi-savoy type. Its leaves have a textured surface, a spatula shape, and are characterized by good density and a medium-dark green color.

The plant is mid-late and is characterized by a slower growth rate compared to similar hybrids. The variety has high adaptability, uniformity, and high resistance to spinach downy mildew (Peronospora effusa, races 1–20).

This hybrid is intended primarily for summer harvest and professional cultivation, in particular for the baby leaf segment, which is due to the stable quality and uniformity of the produce.
