Autotetraploidy and Linkage in Alfalfa— A Study of Resistance to Two Species of Root-Knot Nematodes¹

Synopsis: Resistance to two species of root-knot nematodes (Meloidogyne hapla and M. javanica javanica) in an alfalfa clone selected from Vernal is controlled by single dominant tetrasomic genes for each species. The genes governing resistance to the two species are different but closely linked. One other Vernal selection shows resistance to both species and a third Vernal selection and one from the California Common strain Hilmar show resistance only to M. hapla. Genetic data are less conclusive for these clones, but inheritance seems to be relatively simple.
