Grafting and Budding — Pumpkin (Interspecific Hybrids)

Cucurbita maxima Duchesne x Cucurbita moschata Duchesne

Interspecific hybrids of C. maxima x C. moschata serve as specialized rootstocks for cucurbits, providing a vigorous root system, resistance to soil-borne pathogens, and enhanced stress tolerance for the scion.

In the reference 37 varieties crop Cucurbita maxima Duchesne x Cucurbita moschata Duchesne, where this is mentioned in the description.

These hybrids possess a high degree of compatibility with watermelon, melon, and cucumber, ensuring rapid tissue union. The use of these rootstocks enables plants to better withstand low positive temperatures, drought, and heat, and also effectively resist Fusarium wilt thanks to a complex of immunity established through breeding.

The grafting technology for these hybrids relies on approach grafting, tongue approach grafting, or splice grafting methods. The optimal period for these operations is 2–3 days after emergence, when the rootstock and scion have the same stem diameter. A critically important agronomic practice is the complete removal of the rootstock's growth point to redirect resources toward nourishing the scion.
