Ogle, Professor, Department of Horticulture, Clemson University, Clemson, SC 29634-0377. Plant Dis. 71:399-402. Accepted for publication 27 August 1986.

Each of 16 commonly grown cultivars of southern pea were inoculated with a population of Meloidogyne arenaria race 1 or a population of M. incognita race 3. Both nematodes produced some galls on plants of all cultivars. Nine of the 16 cultivars were resistant to M. incognita race 3, and nine were resistant to M. arenaria race 1. All cultivars had fewer galls caused by M. arenaria than by M. incognita.
