“…Another challenge faced by coffee growers in the state of Minas Gerais is the presence of plant‐parasitic nematodes (PPNs). In particular, Meloidogyne paranaensis, the most destructive PPN of coffee in Brazil (Villain, Salgado, & Trinh, 2018), has expanded its geographic distribution in recent years (Terra, Salgado, Fatobene, & Campos, 2019). This PPN destroys the root system of the coffee tree, especially the feeder roots, which are responsible for the absorption of water and nutrients (Peres et al, 2017), resulting in altered physiological processes and reduced plant growth (Goulart et al, 2019).…”

Climate change greatly influences coffee production, especially in areas infested with plant‐parasitic nematodes. In this study, coffee genotypes showed differences in their morphological and physiological characteristics when subjected to a water deficit and parasitism by Meloidogyne paranaensis. The cultivar IPR 100 had the largest superficial and volumetric root system area, even when parasitized. The two progenies (MG 0179‐1 and MG 0179‐3) and the cultivar Catuaí IAC 62 had a similar surface area (p < .05) when parasitized. However, the root surface area and volume of MG 0179‐3 increased by 96% and 400%, respectively, when parasitized by M. paranaensis. On the other hand, Catuaí IAC 62 had a 31% reduction in root surface area. Catuai 62 and IPR 100 showed higher sensitivity to drought when parasitized because of the increased photochemical sensitivity and reduction in photochemical quenching. In MG 0179‐1 and MG 0179‐3, an increase in non‐photochemical quenching occurred in response to stress, indicating that these progenies use a photochemical response to protect photosystem II. In this work, MG 0179‐3, which is resistant to M. paranaensis, was remarkable because, interestingly, the infestation caused an increase in its root surface area. In addition, MG 0179‐3 had relatively good photochemical performance under water deficit and M. paranaensis parasitism.

“…Meloidogyne exigua is the most widespread species in the state of Minas Gerais, the largest Arabica coffee producer, where it is found in at least 25% of coffee farms (Castro et al, 2008). In recent years, M. paranaensis has expanded its spread to other states, notably to Minas Gerais (Terra et al, 2019). In the states of Paraná and São Paulo, the species most frequently found are M. paranaensis and M. incognita.…”

Coffea arabica rootstock resistant to Meloidogyne paranaensis nematodes

Meloidogyne paranaensis is a species of root‐knot nematode that affects coffee (Coffea arabica L.) tree growth by causing severe damages to the plant root. This study evaluated the agronomic performance of Coffea arabica progenies in an M. paranaensis‐infested field and assessed the compatibility of resistant C. arabica genotype 28‐I‐4 (GEN28) as rootstock for susceptible cultivars. Experiment 1: under field conditions, six progenies were analyzed; the controls were ‘IPR100’ as resistant and ‘Catuaí Vermelho IAC 144’ (CtV144) as susceptible. Experiment 2: under greenhouse conditions, combinations of grafts and rootstocks between susceptible CtV144 and GEN28 were evaluated regarding their resistance to M. paranaensis alongside their noninoculated counterparts. For this, M. paranaensis reproduction factor (RF), total population of the nematode per gram of root system, growth parameters, gas exchange, and water potential (ψpd) were evaluated. In Experiment 1, resistant C. arabica progenies were more vigorous, productive, and showed a population of M. paranaensis threefold‐times lower than that observed in roots of susceptible CtV144. Among the resistant progenies selected in the field experiment, GEN28 was chosen for physiological compatibility study with the traditional cultivar CtV144. In Experiment 2, the CtV144 grafted onto GEN28 led to resistance to M. paranaensis, as well as a higher leaf area and ψpd as compared with nongrafted CtV144. Therefore, the GEN28 holds suitable characteristics to be used as a new Coffea arabica rootstock applied to production of resistant seedlings to Meloidogyne paranaensis nematodes. This technology represents an alternative to keep up coffee activity in infested areas.
