“…The coefficient of variation (CV) found can be considered as low (CV < 20%), which indicates good experimental conduction, grain collection, and processing. Similar estimates were observed by Drumond Neto et al (2017), who observed CVs between 1.7 and 6.1% when assessed beverage quality of six genotypes in two environments in the state of Espírito Santo (Brazil). In assessing drink quality of 130 C. canephora accessions in a single environment, Souza et al (2018) estimated a CV of 13.6%, which was due to a higher genetic variability among the evaluated materials.…”

“…Overall, lower altitudes and higher temperatures accelerate fruit ripening; therefore, it is important to select genotypes of higher adaptability and stability to maintain higher beverage quality in such environments (Martins et al, 2020;DaMatta et al, 2012). Drumond Neto et al (2017) observed significant differences in sensory characteristics of C. canephora grains grown in higher altitudes.…”

This study aimed to evaluate the beverage quality of Coffea canephora genotypes in different environments of the western Amazon to assist plant selection and new cultivar development. To analyze beverage quality, samples of cherry coffee beans were collected separately for each genotype from clonal competition trials installed in the municipalities of Ouro Preto do Oeste, Alta Floresta do Oeste, Porto Velho, and Ariquemes in Rondônia State and Rio Branco in Acre State (Brazil). The beverage quality was assessed using the Robusta Cupping Protocol, which attribute to each genotype a score in a range from 0 to 100, highlighting nuances. Analysis of variance and principal components using reference points were used to quantify genotype x environment interaction (G x E). The analysis of variance indicated that genotypic and G x E interaction effects were significant (p < 0.01). By using a centroid dispersion method, we could identify four clones of low, eight of specific (to favorable or unfavorable environments), and seven of broad adaptability to the environments. The clones BRS 2314, 11, and 17 had average quality scores above 80 in all environments, with potential for specialty coffee production. The clones BRS 1216, BRS 3220, and BRS 3193 presented unstable behavior, with beans of higher quality in some of the evaluated environments. Such inconsistency in clone behavior is caused by unpredictable changes in plant performance in different environments. Our results indicate that both genotypic (clones) and G x E interaction effects are important for the expression of coffee beverage quality. However, the clones BRS 3213, BRS 3210, and BRS 2299 had less prominent nuances, with lower potential for specialty coffee production.
