“…Aporé and was classified as moderately resistant to M. incognita race 1 and highly susceptible to M. javanica. These results are similar to the study by Simão et al (2005), who detected, despite the high reproductive factors, that this cultivar has a good tolerance to the nematode, allowing its reproduction under the minimum inoculum pressure without, however, affecting the production of pods. In the present study, no production data were collected, but the mean root mass of cv.…”

“…Other cultivars, on the other hand, showed low shoot mass and high nematode reproduction, such as cultivars Jalo EPP 12 and BRS Esplendor. This divergence between shoot mass and nematode reproduction leads to the idea of a nonrelationship of these characteristics, making it possible genotypes with good yields even under high nematode reproduction, such as the cultivars Pérola (Simão et al, 2005) and Polder (Wesemael & Moens, 2012) depending, of course, on the nematode species.…”

“…The reproduction of gall-forming nematodes in common bean roots may indicate different degrees of resistance or tolerance between genotypes and, consequently, allow the separation of the most efficient genotypes for the reduction of population growth of Meloidogyne species (Simão et al, 2005). Silva & Campos (2002) also suggest that there is a difference in parasitism among species or nematode isolates, so that a single bean genotype can react differently to the pathogen.…”

“…In this way, resistance and tolerance are characters independent of a host plant. Simão et al (2005), studying M. javanica, noticed that the bean cultivars Pérola and Iapar 81 were considered tolerant, because no reduction in the production of pods was observed even under the occurrence of nematode reproduction. Cultivar Aporé is one of the most resistant to M. incognita (Silva et al, 2005).…”

Identification of common bean genotypes resistant to the root-knot nematodes may be useful for bean breeding programs. The objective of this study was to evaluate the reaction of bean genotypes to M. incognita race 1 and M. javanica. Two independent trials to assess resistance to both root-knot nematodes were carried out with fifty-eight common bean genotypes and six snap bean genotypes. The experiments were arranged in a randomized block design, with three replications and two plants per plot. A total of 10,000 nematode eggs were inoculated per plant 15 days after germination. At forty-five days after inoculation, the root system of each plant was harvested and the nematode eggs were extracted. The number of eggs per gram of root was counted and the Reproduction Factor and the Reduction of the Reproduction Factor were calculated. The performance of the genotypes differed between the trials, indicating different resistance reactions to the nematode species evaluated. The genotypes VP-25 and BRS Valente were resistant to M. incognita race 1. The genotypes Aporé, Ouro Vermelho, Radiante, and CNFP 10793 showed good resistance to both M. incognita race 1 and M. javanica, with potential as source of resistance in breeding programs. There was a significant correlation between root mass and number of eggs. The correlation between nematode reproduction and shoot mass was null.

“…Dry beans are considered good hosts for both Meloidogyne incognita and M. javanica with losses that can reduce pod numbers and seed weight per plant by 65%. Several studies report the occurrence of these root-knot nematodes in P. vulgaris L. cultivars (Simão et al, 2005;Walber et al, 2003). Studies with snap beans have shown that their susceptibility to Meloidogyne spp.…”

This study assessed the reaction of dry bean and snap bean cultivars to infection by Meloidogyne incognita (races 1, 3) and by Meloidogyne javanica, two species of root-knot nematodes. Three independent experiments were done, one for each species or race of Meloidogyne, using randomized complete block designs with four replications (plots) and four plants per plot. A plot with the susceptible tomato cultivar Santa Clara was used in each block to determine the efficiency of the inoculum and to calculate the reproduction rate for each of the genotypes assessed. The bean cultivars Aporé and Talismã were highly resistant to Meloidogyne javanica, slightly resistant to Meloidogyne incognita race 1, and moderately resistant and slightly resistant, respectively, to Meloidogyne incognita race 3. The snap bean cultivars Macarrão Atibaia and Macarrão Preferido were slightly resistant to Meloidogyne javanica and moderately resistant and susceptible, respectively, to Meloidogyne incognita race 1. The reactions of the latter cultivars against Meloidogyne incognita race 3 were very resistant and slightly resistant, respectively. The results of these experiments showed that the dry bean cultivars Aporé and Ouro Negro and the snap bean cultivar Macarrão Atibaia have potential to be used in breeding programs for a broader spectrum of root-knot nematode resistances.
