Infection factors of susceptible and resistant tomato plants inoculated with the avirulent Meloidogyne incognita field population Mi-Vfield and the selected virulent isolate SM2V. Infection factors of four interactions are shown: Roma VF/Mi-Vfield (Sus-Miavr); Roma VF/SM2V (Sus-Mivir); Rossol/Mi-Vfield (Res-Miavr); Rossol/SM2V (Res-Mivir). Infection level was characterized by the numbers of Sedentary Forms per Root System (SFs/RS), Egg Masses per Root System (EMs/RS), Reproduction Potential (RP), and Female Fecundity (FF).Values are expressed as means (n = 9) ± standard deviations. Means were separated by a Duncan’s Test, different letters indicate significantly different means (Significance Level: 0.05).
