Variety description

10 August 2026

The plant is vining and possesses a high level of branching, which contributes to the abundant formation of male flowers. The variety belongs to the mid-early maturity group.

The fruits are spherical in shape, have a low weight of 0.5 to 1 kg, and a light green color, sometimes of the Charleston Gray type. The flesh is yellow, which allows for easy differentiation of the pollinator fruits from commercial watermelons during harvest.

The variety possesses intermediate resistance to Fusarium wilt races 1 and 2, anthracnose race 1, powdery mildew, and Zucchini yellow vein virus.
