Two coffee screening tests were undertaken in order to find out sources of resistance to the nematode M. exigua. Arabica progenies from Ethiopia origin and advanced popu-lations derived from interspecific crosses (Coffea arabica x C. canephora and C. arabica x C. dewevrei) were evaluated. A five point scale (0 point to the roots without galls and 5 points to severely attacked roots) was used for determination of the infection degree. The seedlings root system was analysed four months after the nematode infestation in one of the trial and after twelve months at another trial. The observed results were similar indicating the possibility to reduce considerably the time for the screening test. A reduction of 8.0 per cent on the average height and of 11.5 and 12.0 per cent in the green and dry weight of the infested seedlings was observed in one of this test. From the total of 1692 analysed seedlings, 106 were seleeted without nematode galls. It was verified that the number of resistant plants was particularly high among the populations derived from the C. arabica x C. canephora crosses. Seedlings from the trial carried out at Campinas were also inoculated with spores of the race II of Hemileia vastatrix in a tentative of isolation of resistant plants to both pathogens. Among the populations Arabica x Canephora it was possible to selected 38 seedlings with simultaneous resistance to M. exigua and H. vastatrix. The plants were considered useful for the prosecution of the breeding program.
