Meloidogyne hapla induced distinct galls on the roots of 18 tomato cultivars but not on Lycopersicon peruvianum. M. chitwoodi induced distinct galls on the roots of cultivars Columbia, Roza, Saladmaster, and Yellow Pear and on L. peruvianum. Root growth was significantly (P = 0.05) reduced on cultivars Ace, Columbia, Roza, and Saladmaster infected with M. chitwoodi and on cultivars Columbia, Roza, and Saladmaster infected with M. hapla, compared with the controls. Neither nematode species affected shoot growth.
