Large tree with a drooping pyramidal crown of medium density. Main branches diverge from the trunk at an angle close to straight. Bark on the trunk and main branches is smooth, gray-brown. Predominant type of fruiting structures — simple and complex rings.
Medium-length shoots, straight, round in cross-section, reddish-brown, without hairs. Numerous, large buds on the shoot. Buds are bent, medium-sized, elongated, conical, smooth. Leaves are medium-sized, elliptical, short-pointed, green, smooth, glossy, with delicate venation. Leaf margin slightly serrated, finely toothed, wavy, blade slightly concave, curved upwards, hairless. Petiole long, thin, hairless.
Flower buds medium-sized, smooth, elongated. Flowers medium-sized, small-cup-shaped, white, fragrant. Petals round, short.
Fruits of medium size, weighing 120–160 g, medium uniformity, short- and oval-pear-shaped, with smooth surface, slightly angled near the pedicel. Main color at harvest maturity is green, with a light sunburn covering part of the fruit.
