“…For the interaction between resistant coffee (IAPAR 59) and M. exigua, a post-infectional defense response was observed by Anthony et al (2005), leading the authors to suggest the presence of a hypersensitivelike reaction (HR) in the interaction between coffee and M. exigua. Similarly, Lima et al (2015) characterized histologically the mechanisms involved in resistance of "Clone 14" from C. canephora to M. paranaensis and also visualized a hypersensitive-like reaction in this interaction, as observed in IPR 106 in our work.…”

Meloidogyne species are widely distributed in coffee growing areas in Brazil, where M. paranaensis is responsible to significant losses to the crop. One of the main management strategies is the use of resistant cultivars, such as Apoatã rootstock and cultivars IPR 100 and IPR 106. However, the parasitic relationship between coffee and M. paranaensis in cultivars carrying resistance genes has been poorly understood. The objective of this paper was to characterize the resistance response of Coffea arabica cv. IPR 106 to M. paranaensis. For this, penetration and histopathological studies were carried out using root tissues parasitized by the nematode. 'IPR 106' and 'Mundo Novo' (susceptible cultivar) seedlings were inoculated with 4,000 eggs of M. paranaensis and, 15 days after inoculation (DAI), roots were stained with fuchsine to verify the penetration rates of the nematode. Histopathological studies were conducted at 15, 30, 45 and 60 DAI and nematode reproduction was calculated at 120 DAI. 'IPR 106' did not avoid completely nematode penetration at 15 DAI, although the number of nematodes was 50 % lower than in Mundo Novo, disregarding the hypothesis of a pre-infectional mechanism of resistance that could prevent nematode penetration completely. However, giant cells and collapsed nematodes were observed in 'IPR 106' at 30 DAI, suggesting that the resistance mechanism to M. paranaensis in 'IPR 106' involves a post-infectional response and could be mediated by a hypersensitive reaction.

“…Resistance of the C. canephora Apoatã cultivar is associated with its vigorous root system (BARBOSA, et al, 2014, VILLAIN et al, 2010. The hypersensitivity reaction and impediment to the formation of giant cells is the resistance mechanism most accepted for explaining the incompatibility of the coffee plant to the root-knot nematode (LIMA et al, 2015;SILVA et al, 2013).…”

“…In Central America, the "Nemaya" cultivar, derived from the cross between the clones of C. canephora T3561 and T3751, has allowed the survival and competitiveness of coffee growing in regions infested by Meloidogyne (ANTHONY et al, 2007). Both cultivars are derived from the clone T3561 and exhibit multiple resistance to M. exigua, M. incognita, and M. paranaenses (LIMA et al, 2015).

ABSTRACT:Meloidogynose is prominent among the factors that limit yield in C. canephora in the western Amazon, Brazil. It is caused by species of "root-knot nematode"; the most important and aggressive of these species for coffee is M. incognita. The aim of this study was to assist the selection of resistant genotypes by characterizing the reaction of 32 C. canephora clones to M. incognita (Est I2). These genotypes are selected plants from the Germplasm Bank of Embrapa Rondônia of the botanical varieties Conilon, Robusta and intervarietal hybrids. The experiments were conducted under greenhouse conditions by inoculating six seedlings for each clone with 10 ml of suspension containing 5000 eggs of a pure inoculum of M. incognita. At 150 days after inoculation, evaluations were made of fresh weight of roots (FWR), total number of galls (NG), total number of eggs (NE), and the nematode reproduction factor (RF=final population/initial population). In contrast with the susceptible controls of arabica coffee (RF=1.2) and tomato plants (RF=31.3), six clones of the Conilon botanical variety, five clones of the Robusta botanical variety and eight intervarietal hybrids reacted as resistant to M. incognita, exhibiting RF<1 and a reduced number of galls (NG mean = <10). The clones identified as resistant in this study were integrated in the coffee breeding program in Rondônia for development of cultivars resistant to the root-knot nematode adapted to tropical conditions.

Caracterização da resposta de resistência de genótipos de Coffea canephora ao Nematoide-das-Galhas Meloidogyne incognita (Est I2)RESUMO: Entre os fatores que limitam a produtividade do C. canephora na Amazônia Ocidental destaca-se a meloidogynose, causada por espécies do "Nematoide-das-Galhas", dentre as quais a mais importante e agressiva ao cafeeiro é M. incognita. O objetivo desse trabalho foi caracterizar a resistência à M. incognita (Est I2) de 32 genótipos das variedades botânicas Conilon, Robusta e híbridos intervarietais provenientes do Banco de Germoplasma da Embrapa Rondônia. Os experimentos foram realizados em casa de vegetação com a inoculação de seis mudas para cada clone com 10 ml de suspensão contendo 5000 ovos de inóculo puro de M. incognita. Cento e cinquenta dias após a inoculação foram avaliados o peso fresco (PF), o número de galhas (NG), o número de ovos (NO) e o fator de reprodução do nematoide (FR= população final/população inicial). Em comparação com as testemunhas suscetíveis de café arábica e do tomateiro (FR=1,2 e 31,3, respectivamente), os clones da variedade botânica Conilon (694, 160, 837, 46, 909, 890), da variedade botânica Robusta (1111, 8152, 8192, 10141, 8152) e os materiais híbridos (844, 1005, 169, 54, 453, 120, 193, 636) reagiram como resistentes à M. incognita, apresentando FR<1 e reduzido número de galhas (NG médio = <10). Os clones identificados como resistentes foram integrados ao programa de melhoramento genético do cafeeiro visando o ...

“…Some clones of Conilon coffee cultivar Vitoria Incaper 8142 of C. canephora exhibited multiple resistance to M. exigua, M. incognita, and M. paranaensis (Lima et al, 2015) under controlled conditions. Because Conilon coffee is recommended for regions at low altitudes, the goal of this study was to evaluate the agronomic performance of resistant clones of Conilon coffee cultivar Vitoria Incaper 8142 in areas infested by M. paranaensis in the west region of Minas Gerais.…”

Meloidogyne paranaensis is responsible for considerable losses in coffee production. Because of the distribution of this species in the main Coffea arabica producing regions, there is a need for management practices to ensure the sustainability of coffee production. In this work, we evaluated the agronomic performance of resistant clones of the Conilon coffee cultivar Vitoria Incaper 8142 in areas infested by M. paranaensis in the west region of Minas Gerais, Brazil. Clones 2V, 3V, and 6V presented the lowest number of nematodes per gram of roots and were considered resistant to M. paranaensis. All other clones were considered tolerant to this nematode, and one had good vegetative growth but allowed nematode reproduction. Clones of Vitoria Incaper 8142 of C. canephora represent an alternative to coffee production in areas infested by M. paranaensis including areas traditionally cultivated with C. arabica.
