“…A high proportion of resistant genotypes was observed in the progenies derived from the Amphillo germplasm. Several authors have identified resistance to M. paranaensis in progenies derived from this germplasm 18,19,20,21 . In the progenies from the accessions MG0179-5-R1 and MG0179-3-R1, there was no segregation of resistance.…”

“…In the coffee x M. paranaensis interaction, typical galls may form in resistant cultivars, while susceptible cultivars may not exhibit this type of reaction 10,49,50 . Due to this particularity, score scales based on the gall index and damage index have been adapted to assess the resistance in this pathosystem 19,5,51,50,11,52 . Adapted score scales showed high coefficients of genetic correlation with the number of eggs/second-stage juveniles (J2) and reproduction factor in studies conducted by Fatobene et al 19 and Rezende et al 50 .…”

“…The main commercial cultivars come from narrow genetic bases of Typica and/or Bourbon 15 , showing phenotypic homogeneity 16 and high genotypic similarity 17 . To circumvent these factors, several studies have sought sources of resistance in wild C. arabica accessions from Ethiopia 18,19,20,21 . These authors have observed resistance to M. paranaensis in progenies derived from crosses involving Amphillo germplasm, which have been evaluated in areas infested by the pathogen and pointed out as promising sources of resistance for coffee breeding programs.…”

The phytonematode Meloidogyne paranaensis is one of the main threats to coffee production. The development of Coffea arabica cultivars resistant to this pathogen is an urgent demand for coffee growers. Progenies derived from the wild germplasm Amphillo are considered potential sources of resistance to M. paranaensis, however, the mechanisms involved in this resistance have not yet been elucidated. In the present work, the resistance of different progenies derived from Amphillo was studied and molecular markers associated with resistance were identified. Through the Genomic-Wide Association, SNP markers associated with genes potentially involved in resistance control were identified. A total of 158 genotypes belonging to four progenies derived from crosses between Amphillo and Catuaí Vermelho were analyzed. These coffee plants were phenotyped for five traits related to resistance. A total of 7116 SNP markers were genotyped and, after quality filtering, 931 SNPs were selected to conduct the genome-wide association study. The mixed linear model identified 12 SNPs with significant associations with at least one of the evaluated variables and eighteen genes were mapped. The results obtained support the development of markers for assisted selection, studies on genetic inheritance, and elucidating molecular mechanisms involved in the resistance of C. arabica to M. paranaensis.

“…Several studies, based on this C. arabica Ethiopian germplasm, identified sources of desirable traits, such as resistance to BHB ( Mohan et al., 1978 ); resistance to nematodes Meloidogyne paranaensis , M. incognita , and M. exigua ( Anzueto et al., 2001 ; Fatobene et al., 2017 ; Holderbaum et al., 2020 ); resistance to coffee berry disease ( van der Vossen and Walyaro, 2009 ); drought tolerance ( Queiroz-Voltan et al., 2014 ); biochemical compounds which influence beverage quality ( Bertrand et al., 2006 ); low caffeine content ( Silvarolla et al., 2004 ); and other chemical compounds ( Scholz et al., 2016 ).…”

Bacteria halo blight (BHB), a coffee plant disease caused by Pseudomonas syringae pv. garcae, has been gaining importance in producing mountain regions and mild temperatures areas as well as in coffee nurseries. Most Coffea arabica cultivars are susceptible to this disease. In contrast, a great source of genetic diversity and resistance to BHB are found in C. arabica Ethiopian accessions. Aiming to identify quantitative trait nucleotides (QTNs) associated with resistance to BHB and the influence of these genomic regions during the domestication of C. arabica, we conducted an analysis of population structure and a Genome-Wide Association Study (GWAS). For this, we used genotyping by sequencing (GBS) and phenotyping for resistance to BHB of a panel with 120 C. arabica Ethiopian accessions from a historical FAO collection, 11 C. arabica cultivars, and the BA-10 genotype. Population structure analysis based on single-nucleotide polymorphisms (SNPs) markers showed that the 132 accessions are divided into 3 clusters: most wild Ethiopian accessions, domesticated Ethiopian accessions, and cultivars. GWAS, using the single-locus model MLM and the multi-locus models mrMLM, FASTmrMLM, FASTmrEMMA, and ISIS EM-BLASSO, identified 11 QTNs associated with resistance to BHB. Among these QTNs, the four with the highest values of association for resistance to BHB are linked to g000 (Chr_0_434_435) and g010741 genes, which are predicted to encode a serine/threonine-kinase protein and a nucleotide binding site leucine-rich repeat (NBS-LRR), respectively. These genes displayed a similar transcriptional downregulation profile in a C. arabica susceptible cultivar and in a C. arabica cultivar with quantitative resistance, when infected with P. syringae pv. garcae. However, peaks of upregulation were observed in a C. arabica cultivar with qualitative resistance, for both genes. Our results provide SNPs that have potential for application in Marker Assisted Selection (MAS) and expand our understanding about the complex genetic control of the resistance to BHB in C. arabica. In addition, the findings contribute to increasing understanding of the C. arabica domestication history.

“…Genetic resistance is the most effective method to cultivate coffee in infested soils (Bertrand and Anthony, 2008). Sources of resistance were identified in C. canephora Pierre ex A. Froehner (Bertrand et al, 2000;Sera et al, 2006), in wild Ethiopian C. arabica accessions (Anzueto et al, 2001;Boisseau et al, 2009;Fatobene et al, 2017), and in C. arabica germplasms derived from introgression of C. canephora genes, such as Timor Hybrid Salgado et al, 2014) and in Icatu (Campos and Villain, 2005).…”

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.
