a Resistant phenotypes of LA3858 and Moneymaker at different soil temperatures after infestation by M. incognita. Seedlings of LA3858 and Moneymaker grown at 25 °C, 32 °C and 34 °C soil temperatures for five days before inoculation. At 45–50 days after infection with M. incognita, the roots were dyed with acid fuchsin solution, and the disease resistance was evaluated. b Number of egg masses on the roots of LA3858 and Moneymaker infected by nematodes. Quantities of egg masses on the roots of two different strains, which had been growing under different soil temperatures (25 °C, 32 °C and 34 °C). One-way ANOVA was performed to determine the relevant significance within the same line after inoculation
