The experiments were carried out in greenhouses, in expanded 128-cell polystyrene trays filled with commercial substrate. Lettuce cultivars ‘Salinas 88' and ‘Grand Rapids' were tested along with the populations F1 (‘Grand Rapids'בSalinas-88'), F2 (‘Grand Rapids'בSalinas-88'), F3 (‘Grand Rapids'בSalinas-88'), and with F4 families derived from the latter population. Seedlings were inoculated 15days after sowing with a nematode egg suspension equivalent to 30eggsml−1 of substrate. Plants were evaluated for apparent gall incidence, gall scores, egg mass scores and extracted egg numbers 45days after the inoculation date. There was evidence that two different genes are involved in control of resistance to M. incognita race 1 in lettuce cultivars Grand Rapids and Salinas-88. Lines with higher levels of nematode resistance than either Grand Rapids or Salinas-88 could be selected in the F4 generation of the cross between these resistant parental lines.
