, Resistance to the root-knot nematodes Meloidogyne spp. would be a valuable attribute of lettuce Lactuca sativa L. cultivars grown in tropical regions. The looseleaf lettuce ‘Grand Rapids’ is resistant to both M. incognita and M. javanica. Resistance to M. incognita has a high heritability, under the control of a single gene locus, in which the ‘Grand Rapids’ allele, responsible for resistance (Me), has predominantly additive gene action, and has incomplete penetrance and variable expressivity.
