10 August 2026
The variety originated as a bud mutation of the Thompson variety. The tree is small to medium in size, reaching 4.5–6 meters in height, with a dense canopy, glossy dark green leaves, and fragrant white flowers.
The fruit matures in the winter-spring period. The peel is yellow-orange with a reddish tint, the flesh ranges from light pink to dark red, and the taste is sweet-tart. The variety is characterized as practically seedless; the fruit is suitable for transport and long-term storage on the tree.
The plant requires warmth for the accumulation of fruit sweetness and is sensitive to sub-zero temperatures. The variety is widely used in commercial and home gardening for fresh consumption and industrial processing.
