The nematode of the genera Meloidogyne and the fungi Fusarium may reduce the crop yield. So, the present paper had as objective to evaluate the behavior of nine cultivars and two lines of bean P. vulgaris to the nematode M. javanica the fungi F. oxysporum f. sp. phaseoli (Fofsp) and its interaction. The trials were conducted under greenhouse conditions at randomized design using four treatments replicated eight times for the evaluations made at 35 days, and four treatments for the evaluation at 60 days after inoculation. The first evaluation was determined the number of galls (NG) for M. javanica root system, and severity (SEV) for F. oxysporum f. sp. phaseoli. In assessing the 60 days, the analysis were identical to the first however, it was determined the factor of nematode reproduction (FR). For both evaluations, it was observed that M. javanica alone or in association with F. oxysporum, were parasite of all tested bean cultivars and lines. For F. oxysporum alone the cultivars 'Perola', 'IAPAR 14' and the line LP99-85, behaved as resistants. For the cultivar 'Perola', it was observed a significant increase of severity of the symptom of Fusarium when the fungi associated with M. javanica.
