Average (n=10) reproduction factor (RF) and galling index (scale 0 – 10 = 0 = no galling and 10 = 100% of root system galled) on seven different tomato cultivars inoculated with five resistance-breaking root-knot nematode (Meloidogyne) populations (1,000 second-stage juveniles/pot) and an avirulent M. incognita race 3 population in a greenhouse pot trial.
