Variety description

10 August 2026

The tree is vigorous, with a spreading crown. The variety is characterized by high precocity and regular yields, with mid-late flowering. The plant is resistant to fungal diseases and not prone to fruit cracking during autumn precipitation. The variety is self-incompatible and requires the presence of other diploid plums for pollination.

Fruits have an oblong-round shape; the skin color at maturity ranges from yellow-pink to red-violet. The flesh is yellow, firm and juicy, with low acidity and high sugar content. The stone is small, semi-freestone. The variety is distinguished by high keeping quality and suitability for transport.
