Item MGS Aranãs: the new Arabica coffee cultivar developed by Epamig with wide adaptation(Editora UFLA, 2021) Botelho, Cesar Elias; Abrahão, Juliana Costa de Rezende; Pereira, Antônio Alves; Oliveira, Antônio Carlos Baião de; Carvalho, Gladyston Rodrigues; Ferreira, André DominghettiThis paper describes the MGS Aranãs cultivar (H32-11-17-4-2-MS-MS) resulting from a cross between the cultivars Icatu 3851-2 and Catimor. The MGS Aranãs cultivar is characterized by small size, ripe red fruits, large seeds, coffee leaf rust resistance, an architecture suitable for densification, production stability, and high beverage quality. This new cultivar is recommended for the Sul de Minas, Cerrado Mineiro and Vale do Jequitinhonha regions.Item Sensory quality of Coffea arabica L. genotypes influenced by postharvest processing(Crop Breeding and Applied Biotechnology, 2019) Barbosa, Ivan de Paiva; Oliveira, Antonio Carlos Baião de; Rosado, Renato Domiciano Silva; Sakiyama, Ney Sussumu; Cruz, Cosme Damião; Pereira, Antônio AlvesThe specialty coffee market has grown significantly in the past decades and has several cultivars with productive potential. The objective of this study was to evaluate the sensory profile of the beverage produced from Coffea arabica L. genotypes based on postharvest processing and to identify cultivars with the greatest genetic potential for coffee cultivation in the city of Araponga, Minas Gerais, Brazil. The experiment was a randomized complete block design with two replicates and 11 genotypes with different levels of resistance to rust. The sensory profile demonstrated an interaction between the genotype and the processing technique. Five of the genotypes presented total scores above 85 points according to the SCAA protocol. Moreover, two of these genotypes yielded heightened sensory notes after undergoing dry processing. The selection of coffee genotypes should consider the level of technology involved in the drying of the coffee beans, which preserves the potential quality of the beverage.Item Sensory profile of arabica coffee accesses of the germplasm collection of Minas Gerais – Brazil(Editora UFLA, 2019-07) Fassio, Larissa de Oliveira; Pereira, Rosemary Gualberto Fonseca Alvarenga; Malta, Marcelo Ribeiro; Liska, Gilberto Rodrigues; Sousa, Maísa Mancini Matioli; Carvalho, Gladyston Rodrigues; Pereira, Antônio AlvesThis study was developed to determine the beverage quality and the sensory profile of Coffea arabica 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.
