Root knot nematodes (Meloidogyne spp.) cause immense yield losses in crops throughout the world. Use of resistant germplasms of plants limits the root knot nematode damages. In this study, 87 common bean (Phaseoulus vulgaris L.) genotypes were screened against the root knot nematode, Meloidogyne incognita to determine the resistance response under growth chamber conditions in Turkey. P. vulgaris genotypes were evaluated based on resistance index (RI); root galling severity and nematode egg mass production on a 1-9 scale. The nematode negatively influenced the growth (fresh weight) of bean genotypes. At the completion of the study, 13 bean genotypes were found as immune (Sehirali), highly resistant (TR42164, Seleksiyon 5, Seker Fasulye, Fas-Agadir-Suk-1) and moderately resistant (Acik Badem, TR68587, TR43477, TR53827, TR28018, Gülnar-3, Siyah Fasulye, Kibris Amerikan) against M. incognita thus suggesting the use of such genotypes in breeding studies as a parental material to develop the root knot nematode resistant cultivars. © 2015, Agricultural Research Communication Centre.
