Variety description

10 August 2026

The hybrid is the result of crossing Cucurbita maxima Duchesne and Cucurbita moschata Duchesne. Its primary functional purpose is its use as a rootstock for growing watermelons, cucumbers, and other cucurbit crops.

Using the plant as a rootstock is aimed at ensuring the resistance of grafted crops to adverse soil conditions and the impact of soil-borne pathogens. Data on the nutritional characteristics of the hybrid's fruits are absent in open sources, as it is not intended for human consumption.
