Development of a SNP-based CAPS assay for the Me1 gene conferring resistance to root knot nematode in pepper
MetadataShow full item record
Root knot nematodes (Meloidogyne spp.) are significant agricultural pests on many crops, including pepper (Capsicum annuum). Host plant resistance offers the most sustainable means of controlling this pest. A cluster of genes on chromosome 9 confers resistance, with Me1 providing protection against three nematode species: M. incognita, M. javanica and M. arenaria. We describe the development of a codominant CAPS marker located 1.13 cM away from the Me1 gene. This marker should be useful for marker assisted selection of nematode resistance in pepper breeding programs.
