dcterms.abstract | Over 150 bean (Phaseolus vulgaris) pure lines and accessions were evaluated in growth chamber and greenhouse trials for reactions to one or more populations of root-knot nematodes (Meloidogyne spp.) collected from Colombia or the United States. Bean pure lines and accessions were evaluated for root galling severity and nematode egg mass production on a 1 9 scale, where 1 = no root galling or no egg mass production and 9 = 76 100% of root system galled or >100 egg masses per root system. A resistance index (RI) was generated for each pure line or accession by combining the root galling severity and nematode egg mass production ratings such that RI = (root galling severity rating2 + egg mass production rating2). Reaction classes were defined as immune (RI = 2), highly resistant (RI = 3 8), resistant (RI = 9 18), moderately resistant (RI = 19 32), intermediate (RI = 33 50), moderately susceptible (RI = 51 72), susceptible (RI = 73 98), and highly susceptible (RI = 99 162). Only about 30 bean lines and accessions had a response of moderately resistant or better (RI <33) to the populations of Meloidogyne spp. used. Among those highly resistant to root-knot nematodes were A 211, Carioca, Manoa Wonder, Nemasnap, and PI 313709. These pure lines and accessions can be used as valuable parental materials in the development of root-knot-resistant bean cultivars adapted for Colombia, Peru, and other countries. | en |
