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 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.Item Caracterização de genótipos de Coffea arabica L. em área infestada pelo nematoide Meloidogyne paranaensis(Editora UFLA, 2017-01) Carvalho, Alex Mendonça de; Salgado, Sonia Maria de Lima; Mendes, Antônio Nazareno Guimarães; Pereira, Antônio Alves; Botelho, Cesar Elias; Tassone, Guilherme Augusto Teixeira; Lima, Renato Ribeiro deMeloidogyne paranaensis provoca sérios danos ao sistema radicular dos cafeeiros podendo causar o mau desenvolvimento vegetativo e reprodutivo culminando com a morte de plantas. Objetivou-se avaliar, em área naturalmente infestada por M. paranaensis, o crescimento vegetativo, a produção no primeiro biênio (2011/2012) e a população de M. paranaensis nos genótipos (GEN) Híbrido de Timor UFV 408-01 pl.1 R1 GEN 5); Sarchimor pl.1 R1 (GEN 34); dos cruzamentos de Catuai Vermelho x Amphillo 2161 pl.1 R1 (GEN 15); Catuai Vermelho x Amphillo 2161 pl.3 R1 (GEN 21); Catuai Vermelho x Amphillo 2474 pl.1 R2(GEN 22) e das testemunhas (cultivares IPR 100, Catuaí Amarelo IAC 62 e Mundo Novo 379-19). No trabalho avaliaram-se a população (ovos+Juvenis de segundo estádio.g -1 de raiz) de M. paranaensis, produção no primeiro biênio, vigor vegetativo, diâmetro de copa, altura da planta e tamanho do grão. Os resultados permitem concluir que: em área infestada por M. paranaensis, o GEN 15 (Catuai Vermelho x Amphillo 2161 pl.1 R1) foi o mais semelhante ao IPR 100 nas características agronômicas avaliadas; o GEN 21 apresenta elevada produção, além de alta população de M. paranaensis, indicando um comportamento de tolerância ao nematoide e o GEN 34 apresenta suscetibilidade ao nematoide M. paranaensis.Item Genetic progress in coffee progenies by different selection criteria(Editora UFLA, 2014-07) Rezende, Juliana Costa de; Botelho, Cesar Elias; Oliveira, Antônio Carlos Baião de; Silva, Felipe Lopes da; Carvalho, Gladyston Rodrigues; Pereira, Antônio AlvesIn order to investigate the aspects related to the use of selection indexes in Coffea arabica breeding, analytical procedures were used: index based on the sum of ranks of Mulamba and Mock (ISR), index of desired gains of Pesek and Baker (DGI), classic index of Smith and Hazel (CI), base index of Williams (BI), and direct and indirect selection (DIS). Thirty-nine progenies were evaluated in the 4 th generation by selfing after the 2 nd backcross between “Catuai” and “Mundo Novo”. The evaluations were realized in coffee plants from 30 months old on, having the following characteristics: yield of eight harvests, classification for blend 16 and over, percentage of floating fruits, vegetative vigor and percentage of flat beans. The analytical procedures of selection indexes showed possibilities of applications in advanced generations of breeding being superior when compared with DIS. The DGI was not appropriate in the situation analyzed in this work. The selection based on CI and BI was the criteria that showed the best results in terms of gains in yield and grain size, and in the distribution of gains in the other characteristics.
