2012 Annual Report
Ten selected Cucumis metuliferus (African-horned cucumber) rootstocks were evaluated for compatibility with the scion ‘Athena’ melon in field trials in Charleston, SC. A number of these rootstocks were highly compatible with melon. Greenhouse studies were conducted to evaluate response of selected cucurbit lines against southern root-knot nematode (Meloidogyne incognita) in order to identify additional potential resistant rootstocks (RKN) for grafted melon. Compatible melon scion and root-knot nematode resistant rootstock (RKN) combinations will be useful for managing RKN in susceptible speciality melons in nematode-infested fields in the Southeastern U.S. Fifteen commercially available rootstocks used in cantaloupe grafting were screened for their reaction to the Fusarium wilt pathogen. The majority of these rootstocks were found to have non-host resistance to both race 1 and race 2 of this fungal pathogen. In addition, several experimental rootstock lines of Cucumis metuliferus were also screened following infection by race 1 and 2 and all were found to have non-host resistance. The use of non-host resistance should work well in grafted cantaloupe for protection against Fusarium wilt.
