Abstract
The reactions of lines and cultivars of common bean (Phaseolus vulgaris) to Italian populations of races 1 and 2 of Meloidogyne incognita, M. javanica, race 2 of M. arenaria and M. hapla were evaluated in a glasshouse. Groups of ten pregerminated seeds of each line or cultivar of common bean were sown in trays of 12 dm3 filled with a steam sterilized sandy soil artificially infested with 10,000 eggs and juveniles of each nematode population per plant. The lines Alabama #1 and PI 165426 were resistant to all populations of Meloidogyne spp. tested. The line A 445 was resistant to M. incognita race 2 and M. javanica, and segregated for resistance to M. incognita race 1. The inbreed line ISCI 197/151-5 was resistant to M. incognita race 1, M. arenaria race 2 and M. hapla. The remaining lines and cultivars were susceptible to all four species of root-knot nematodes.
