Abstract
The use of sweet potato germplasm resistant to root nematodes has allowed breeding programs to obtain new and more productive cultivars resistant to pests and diseases, constituting an important alternative control.
The objective of this study was to evaluate the response of clones of sweet potato (Ipomoea batatas (L.) Lamarck) for resistance to root knot nematodes of the genus Meloidogyne spp. and selecting resistant clones for use by producers or in breeding programs.
The clones are from the Germplasm Bank of Embrapa Vegetables (CNPH) and are maintained in a clonal garden in Agua Limpa Farm at the University of Brasilia (FAL/UnB). The experiment was performed using an experimental design of randomized blocks in a simple arrangement, with 25 treatments and four replicates and six clones of sweet potatoes per plot.
Among the clones, 87.5% showed resistance to Meloidogyne spp.
