Variety description

10 August 2026

Big Jack belongs to the category of early-maturing hybrids with a ripening period of 81–82 days. The plant is characterized by a vigorous growth habit and a well-developed leaf canopy, which protects the fruits from sunburn.

The fruits have a blocky-oval shape, dark green color with stripes, and are distinguished by high uniformity and sugar content. As a triploid hybrid, the variety does not contain hard seeds.

The variety is intended for cultivation in the open field and possesses intermediate resistance to Fusarium wilt (races 0 and 1) and anthracnose (race 1).
