Variety description

10 August 2026

The tree is characterized by moderate growth, reaching a height of 2.5–4.5 meters depending on the rootstock, with an upright-spreading crown. The variety is self-fertile and does not require the presence of pollinators.

The fruits are large, weighing 35–60 g, round-oval in shape with thin yellow-green or golden-yellow skin. The flesh is golden, juicy, and sweet. The ripening period varies from the end of July to the middle of August.

The variety has good winter hardiness and resistance to plum rust, however, it may be susceptible to bacterial canker and fruit rot. The fruits are suitable for fresh consumption and processing, but are sensitive to transportation.
