Research Project: Integrated Grafting Technology to Improve Disease Resistance and Fruit Yield in Speciality Melon Production

Location: Vegetable Research

Project Number: 6659-22000-026-01
Project Type: Reimbursable

Start Date: Jul 15, 2010
End Date: May 30, 2014

Objective:
Identify effective rootstocks for managing Fusarium wilt and root-knot nematodes in grafted specialty melon production in the Southeastern U.S.

Approach:
Commercial rootstocks, wild germplasm, and elite cultivars of bottle gourd (Lagenaria siceraria), hybrid squash (Cucumis moschata x C. maxima), winter melon (Benincasa hispida), Cucumis metulifer, Cucumis ficifolia, and cantaloupe (Cucumis melo) will be evaluated for resistances to Fusarium wilt (Fusarium oxysporum f. sp. melonis) and southern root-knot nematode (Meloidogyne incognita) and for graft compatibility with melon in greenhouse tests in SC. The five most resistant and graft-compatible genotypes will be evaluated as rootstocks for two desirable melon cultivars (scions) in fields infested with F. oxysporum f. sp. melonis and M. incognita in Charleston, SC. Vine vigor, incidence and severity of Fusarium wilt, and severity of root galling caused by root-knot nematode will be rated, and fruit yield will be recorded.
