Variety description

10 August 2026

The hybrid belongs to the Tetsukabuto variety type and represents a combination of the species Cucurbita maxima and Cucurbita moschata. Its primary purpose is to increase crop resistance to soil-borne pathogens and adverse stresses, and to improve the overall life cycle of grafted plants.

The plant forms a very strong, thick, and fleshy stem, and the seedlings are characterized by high uniformity, which is important for a successful grafting process. The hybrid possesses high tolerance to Fusarium wilt, as well as resistance to fungal infections such as Pythium and Rhizoctonia.

The breeding is focused on the development of a powerful root system and ensuring affinity with scions. The fruit quality of the rootstock itself is not a target characteristic, as it is intended for professional vegetable production exclusively as a technological tool.
