“…In this study, the genotypes MG 0179‐1 and MG 0179‐3 had RFs < 1, confirming their resistance to M. paranaensis as presented by Salgado et al (2014) and Peres et al (2017). On the other hand, cultivar IPR 100, which had an RF < 1 in other studies (Andreazi et al, 2015; Sera et al, 2017), had an RF slightly greater than 1 in this study. This difference in the value of the RF may be related to the physiological differences in the nematode aggressiveness.…”

“…The relatively high root surface area and volume of the Catuaí IAC 62 and IPR 100 cultivars resulted from the intensive selection of breeding programmes and make them successful cultivars for growers compared with progenies that have yet to enter the market. Sera et al (2017) and Martins, Pedroso, Fazuoli, and Gonçalves (1992) demonstrated the high potential for the production of Catuaí 62 and IPR 100, highlighting them among other cultivars in the field. Nevertheless, when a field is infested by M. paranaensis, the yield potential of Catuaí 62, indicated by the robust root system, is decreased due to a reduction in the root surface.…”

“…The genotypes MG 0179‐1R1‐776 and MG 0179‐3R1‐151, from the breeding programme of EPAMIG, were selected because of their resistance to M. paranaensis (Peres et al, 2017). The commercial cultivar Catuaí Amarelo IAC 62 was used as a susceptible control, and the commercial cultivar IPR‐100, which is derived from a cross between C. arabica × C. liberica and has resistance genes inherited from C. liberica , was used as a resistant control (Sera et al, 2017; Santos et al, 2018).…”

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.

“…Except for IPR 100 (Sera et al, 2017) and IPR 106 (Ito el al., 2008), most Coffea arabica L. cultivars are highly susceptible to M. paranaensis. Genetic resistance is the most effective method to cultivate coffee in infested soils (Bertrand and Anthony, 2008).…”

Plants of Coffea arabica Icatu IAC 925 germplasm show resistance to Meloidogyne paranaensis under field conditions, but with variable rates of segregation. One mother plant, IAC 3, of Icatu IAC 925 was evaluated under controlled conditions through the reaction of its clones, obtained by somatic embryogenesis. Reproduction of nematodes in clones were compared with an open-pollinated progeny from the same mother plant, C. arabica cultivar Mundo Novo IAC 515-20, susceptible to nematodes, and Clone IAC 1, also susceptible and obtained by somatic embryogenesis. Open-pollinated progeny showed segregation to resistance and was classified as susceptible according to the reproduction factor. The average number of nematodes (eggs and J2) per gram of roots in clones was eight fold lower than that of open-pollinated progeny,and 51 fold lower than Mundo Novo IAC 515-20. Based on Seinhorst model, IAC 3 clone showed a tolerance limit of 7.7 nematodes per cm 3 of soil, while in Mundo Novo the tolerance limit was 3.9 nematodes per cm 3 of soil. These results revealed that clonal Arabica coffee nematoderesistant trees represent an alternative to the time consuming and expensive process inherent to conventional breeding strategies.

“…IPR 100 is the only one cultivar that has been widely grown in infested areas in Brazil and presents resistance level to M. paranaensis similar to rootstock C. canephora cv. Apoatã IAC 2258 (Andreazi et al, 2015a;Sera et al, 2017). In the coffee breeding program of IAPAR, Arabica coffee cultivars resistant to nematodes have been developed using 'IPR 100' as resistance source, which is resistant to M. paranaensis.…”

The aim of this work was to evaluate the reaction of IPR 100 derived Arabica coffee lines to the nematode Meloidogyne paranaensis and to investigate the association between the parameters used to select resistant genotypes. The experiment was carried out in a greenhouse at IAPAR in Londrina -PR, Brazil. The resistance to M. paranaensis of nineteen Coffea arabica F 3 lines derived from the cross "PRFB E9705-9" × 'IPR 100' and three from the cross 'IPR 100' × "Sarchimor E9601 III-19-1" were assessed. Plants with three to four pairs of leaves were inoculated with 5000 M. paranaensis eggs and J 2 juveniles. After 90 days of inoculation, the variables reproduction factor (RF), fresh weight of roots (FWR) and number of eggs and J 2 juveniles per gram of roots (Nematodes.g -1 ) were assessed. Reduction in the reproduction factor (RRF) and host susceptibility index (HSI) were used to classify the resistant levels. Resistant lines were identified and the use of RRF, HSI and RF indices together helped to identify genotypes with resistance to nematodes. In the present study, statistical difference between the FWR of the genotypes was observed. Thus, if the indices are used alone, it is likely that HSI is better, since it can minimize possible interference in the classifications due to differences between the root volumes of the assessed genotypes. The percentage of plants with different resistance levels based on the classification of RRF and HSI and percentage of resistant plants based on RF are useful to identify homozygous and heterozygous genotypes.
