“…These results indicate that both the effects of genotypes (clones) and the effect of the GxE interaction are important for the expression of the beverage quality. Significant effects of the genotype × environment interaction in coffee growing were also reported in other studies (Barbosa et al, 2012;Borém et al, 2019;Laviola et al, 2007;Fonseca et al, 2019;Moura et al, 2017).…”

Most of the Western Amazon coffee production is made from growing unregistered clones, selected by the coffee growers themselves. The aim of this study is to evaluate the sensory profile and genetic diversity of the most cultivated Coffea canephora clones in the Western Amazon. Coffee samples at cherry stage of the clones 03, 05, 08, 25 and 66 were collected at eight municipalities in the main coffee growing zones, with altitudes ranging from 86 to 381 meters. Beverage quality was evaluated according to the Robusta Cupping Protocols and estimates of the genotype × environment interaction (GE) were made interpreting non-parametric and multivariate methods. The GE interaction was significant and the genetic component was also important to the expression of beverage quality (h 2 =82,23). The clones 25 and 05 have good attributes and mean score near 80 points. Sweetness was the sensory descriptor with the greatest impact on beverage quality of these two clones. Harshness was the descriptor that had the greatest negative impact on beverage quality of clone 66. The clones had complexities that differed and that were not necessarily associated with greater beverage quality. Despite the differences in their beverage attributes, these clones that are grown for their high productivity presented low genetic diversity of the beverage quality.

“…More studies are necessary to recommend suitable cultivars for organic production in different coffee regions. According to Moura et al (2014Moura et al ( , 2017, the low productivity of organic orchards is due, in part at least, to the fact that the cultivars in use are the same as those used by conventional cultivation systems and, in general, are equally susceptible to the rust fungus H. vastatrix. These authors have studied the adaptability and stability of 30 coffee cultivars under an organic system in six different environments in the state of Minas Gerais, Brazil and have determined that five cultivars (IBC Palma 1, Catucaí Amarelo24/137, Sabiá 708, Oeiras MG 6851, and H 518) were widely adapted, stable, productive, and suitable for organic cultivation in this region.…”

“…The efficient production of organic coffee presents several challenges, including selecting cultivars that are more adapted to this system of cultivation (Moura et al, 2014(Moura et al, , 2017, and managing pests and diseases. The main problems, however, are nutritional in nature (Paulo et al, 2001(Paulo et al, , 2006Moreira et al, 2014;Cardoso et al, 2018a).…”

The coffee sector is estimated to have a retail market value in excess of USD 83 billion, and over 125 million jobs have been created in the global coffee chain. The coffee specialty market has recently increased significantly, generating opportunities to certify coffee beans produced by sustainable practices. This avoids practices potentially harmful to the environment. Agroforestry, organic farming, intercropping, and soil conservation strategies are examples of sustainable alternatives in the production of coffee. In this review, we focus on practices for the sustainable management of coffee plantations that can help farmers fight problems caused by global warming. More specifically, we address soil organic matter and microbiota, the use of Urochloa grass as intercrop in coffee plantations, shading systems (including agroforestry), and organic coffee production. We concluded that from the agronomic viewpoint, we already have production techniques that can replace traditional ones with significant advantages accruing to the quality of coffee orchard ecosystems. Nevertheless, we need scientific research efforts to deal with the existing gaps and the engagement of the whole coffee chain as a means of guaranteeing an adequate profit to those smallholders who adopt and maintain sustainable practice and are capable of bringing several positive changes to the coffee crop, including the use of microbia-based commercial products and new organic sources of nutrients to complement chemical fertilizers and improve coffee quality.

“…The GGE biplot model (genotype main effects + genotype by environment interaction) is based on principal component analysis to represent the response of genotypes in a set of environments, quantifying the interaction in twodimensional diagrams that show the relations between the environments and genotypes (YAN et al, 2007). In addition, it has the advantages of using reference points in principal component analyses, as performed in the centroid method (MOURA et al 2017).…”

Growing Coffea arabica in regions of the Western Amazon is limited by early maturation and by its limited adaptation to regions of low altitude and high temperature. The aim in this study was to quantify the genotype × environment interaction of C. arabica lines in four different environments of the Western Amazon, seeking to assist selection of new lines with greater adaptability and stability for the region. In the months of December 2012 and January 2013, four competitive trials were set up in municipalities of the states of Rondônia and Acre. Each trial was composed of 21 lines and 4 reference cultivars evaluated as controls recommended for planting in the southeast region. In combined analysis, significant differences were not detected between the cultivars and controls; the mean yield of hulled coffee was 12.05 bags ha-1. The Alta Floresta Do Oeste environment has higher yield and is the only environment favorable for growing C. arabica; that environment is differentiated from the others through its higher altitudes and low temperatures. Through GGE biplot analyses, lines 12 and 13, identified as H514-7-10-6-9 and H514-7-10-6-2-3-9, were found to have results superior to the controls in the municipality of Alta Floresta Do Oeste, RO. The gain from selection of 56% obtained from line G12 and the gain of 46% obtained from line G13 show performance superior to the best control. The germplasm studied does not have genetic variability that contributes to selection of plants for adaptation to the low altitude and high temperatures in the amazonic region.
