solution once a week. When plants were 3 weeks old, they were
inoculated with 1500 eggs of either M. javanica or M. incognita
per pot, by injecting 5 ml nematode suspension into five, 5-cm
deep holes in the soil. Root galling index was recorded 6 weeks
after ioculating, assessed on a scale of 0–5: 0 = no galled roots;
1 = 1–20% galled roots; 2 = 21–40% galled roots; 3 = 41–60% galled
roots; 4 = 61–80% galled roots, and 5 = 81–100% galled roots. The
number of nematode eggs per plant was also recorded for selected
