Preliminary evaluation of meloidogyne incognita race 3 reproduction on garden pea cultivars in Brazil

Abstract

Thirteen garden pea cultivars, were assessed for the reproductive rate of the root-knot nematode Meloidogyne incognita race 3 under greenhouse conditions. Two-week old plants growing were inoculated with 5.000 eggs. The nematode reproduction data was determined 55 days later according to the three adopted evaluation criteria (root-gall and egg-mass indexes, reproduction factor, percentage of reduction of the reproduction factor in relation to the susceptible standard cultivar). The tested cultivars were rated as highly susceptible ('Trolly'. 'Jurema'), susceptible ('Luiza'. 'Mini'. 'Asterix', 'Verde Temprana') or moderately susceptible ('Marina', 'Telephone'., 'Dileta'. 'Bolero', 'Flávia'. 'Viçosa', and 'Maria') hosts for the nematode.
