“…This fact can be observed in Table 4, where the sensory analysis separated the coffee cultivars into five statistically distinct groups for wet processed coffees and in four groups for naturally processed coffee. Several authors also found sensory diversity among cultivars in Southern and Southeastern Brasil, including modern (derived from Hibrido de Timor) and traditional cultivars as superior (PEREIRA et al, 2010;KITZBERGER et al, 2011CHALFOUN et al, 2013SCHOLZ et al, 2013;SOBREIRA et al, 2016). .00 a 84.50 a 14.25 a Means followed by the same letter in the columns belong to the same group by the Scott-Knott test at 5% probability.…”

Despite the great diversity of available Arabica coffee cultivars it is observed that, even when presenting different phenotypes of interest, new cultivars are adopted at a slow pace by coffee growers. One possible reason may be the lack of information on the performance of these genotypes in different regions and culture conditions. The aim this work was to verify the performance of twelve coffee cultivars in relation to morphoagronomic characteristics at initial stage of development, as well as the beans quality, in a condition of typical cultivation of the Cerrado. The trial was carried out in the municipality of Monte Carmelo - MG, in randomized block design, with four replicates. Morphoagronomic characteristics were evaluated 15 months after the implantation of the crop. The productivity and, subsequently, the quality of the beans, were evaluated at 18 months. Statistical analyzes were performed using the Genes software. The data were submitted to analysis of variance. The F test was used to determine the significance of treatments. The means were grouped by the Scott-Knott test (1974) at 5% probability and the experimental precision was verified by the estimation of the experimental variation coefficient (CV) and the selective accuracy. The sensory attributes were evaluated in a radar diagram, called “Sensogram”. Genetic variability was observed among cultivars for the vegetative characters. The cultivars Catuaí Vermelho IAC 144 and MGS Aranãs stood out as more productive, with a high percentage of sieve 16 and above and low percentage of grain type mocha. All the cultivars stood out as special, with emphasis on the cultivar Bourbon Amarelo IAC J10 in the wet processing and Catuaí Vermelho IAC 144 in the natural processing.

“…This behavior indicates that these accesses do not suffer many variations as a function of the year of harvest regarding the quality of beverage and even being considered special by the SCA protocol, the maximum quality potential is lower when compared to the other accesses we evaluated. In previous studies, Sobreira et al (2016) also found low sensory potential for the access 20, which composed the cluster of accesses with final scores from 79 to 80 points.…”

“…In addition to being resistant to coffee tree diseases, several studies confirm that the Híbrido de Timor germplasm can be used as a source of genes to improve other characteristics of interest, such as coffee beverage. In this sense, Sobreira et al (2016) evaluated the quality potential of the cross between BE5 Wush-Wush and Híbrido de Timor and observed final scores between 83.0 and 85.5 points. In addition, it is observed that all accesses of Híbrido de Timor in the second year of harvest, remained in group 1, corroborating with some authors that the Híbrido de Timor germplasm has high potential for producing higher quality coffee (Kathutima et al, 2009;Sobreira et al, 2015a;Sobreira et al, 2015b).…”

“…Little is known about the beverage quality of the accesses of the GC of Minas Gerais. In this sense, Sobreira et al (2015a) and Sobreira et al (2016) evaluated some accesses of this collection regarding the sensory quality and observed wide genetic variation for the sensory attributes of the beverage. Thus, it is necessary to better understand the quality potential of the germplasm implemented in Minas Gerais, to support coffee improvement programs aimed at obtaining new cultivars for the production of specialty coffees.…”

This study was developed to determine the beverage quality and the sensory profile of <em>Coffea arabica</em> accesses of the Germplasm Collection of Minas Gerais State in two consecutive harvests. Mature coffee fruits from 49 accesses were selectively harvested in the 2015 and 2016 harvests, and after processing and drying they were sensorially evaluated by a team of trained judges in accordance to the protocols of the Specialty Coffee Association. The data were analyzed by Principal Component Analysis, Cluster Hierarchical Analysis, and Content Analysis. The year of harvest influences the scores of the sensory attributes of the beverage of some coffee accesses. The access 27 (Pacamara) stood out with the highest sensory score seen in the first year of harvest. The accesses 36 (Timor Hybrid UFV376-52) and 43 (BE5 WushWush) stood out for the final sensory score in the two years of evaluation. All accesses belonging to the Timor Hybrid Germplasm stood out in the beverage quality in the second year of harvest. A total of 139 sensory attribute descriptors were identified, and the content analysis showed different levels for the frequency of terms in each access group formed as a function of quality. The Germplasm Collection of Minas Gerais has a wide variability for the production of superior quality coffees, and the year of harvest influences to a greater or lesser degree the potential of quality of the accesses.

“…Several studies are developed with the aim of identifying the most promising genetic materials for obtaining specialty coffees (Scholz et al, 2013;Gimase et al, 2014;Carvalho et al, 2016;Kitzberger et al, 2016;Sobreira et al, 2016). The identification of the outstanding accessions for each genealogical group demonstrates which are the accessions with greater stability of chemical compounds and consequently more promising for the production of special beans, within the Active Germplasm Bank of Minas Gerais.…”

This work aimed to characterize and discriminate genealogical groups of coffee as to the chemical composition of the grains through the model created by PLS-DA method. 22 accessions of Coffea arabica, from the Active Germplasm Bank of Minas Gerais, were divided into groups according to the genealogical origin. Samples of ripe fruits were harvested selectively and processed by the wet method, to obtain pulped coffee beans, with 11% (b.u.) of water content. The raw beans were assessed as to the content of polyphenols, total sugars, total lipids, protein, caffeine, sucrose, and fatty acids. The data were submitted the chemometric analysis, PCA and PLS-DA. The results of PLS-DA identified the variables which most influence the classification of genealogical groups and possible chemical markers to accessions processed by the pulped method. The sucrose content was an important marker for the Exotic accession group. However, the content of polyphenols has been identified as a marker for the group Tymor Hybrid, and the caffeine for the bourbon group. The different fatty acids have been identified as markers for all genealogical groups, at different levels. The model PLS-DA is effective in discriminating genealogical groups from the chemical composition of the beans.
