What is a Carolona Strongback?

‘Carolina Strongback’ is a new rootstook material for grafting watermelon. It has resistance to Fusarium wilt races 1 and 2, as well as tolerance to root knot nematodes.

Carolina Strongback was derived from two wild and seed production. watermelon species, each with resistance to Fusarium wilt race 1 and 2, with targeted selection for grafting qualities.

This material would be used by seed companies, vegetable grafting companies and watermelon growers as a rootstock for growing susceptible watermelon cultivars (scion) in soils infested by the watermelon Fusarium wilt pathogen and root knot nematodes.

Tri-Hishtil brings together three pioneers in the agricultural industry from around the world to the Mountains of North Carolina to become a leader in plant grafting. Grafting is a very detailed procedure whereby a growth booster (the rootstock) is combined with a promise (the scion). The actual grafting of vegetables with soft tissue stems is an extremely sensitive process, but results in a strong plant with resistance against specific soil-borne diseases.
