Item Initial productive performance of coffee progenies in an area infested by Meloidogyne paranaensis(Editora UFLA, 2018-10) Santos, Henrique Frederico; Salgado, Sonia Maria de Lima; Mendes, Antônio Nazareno Guimarães; Carvalho, Alex Mendonça de; Botelho, Cesar Elias; Andrade, Vinicius TeixeiraIn this study, we aimed to carry out a selection of Coffea arabica progenies in areas infested by Meloidogyne paranaensis in order to select materials that are resistant to this nematode, with desirable agronomic characteristics. The experiment was set on Guaiçara Farm, located in the Municipality of Piumhi – MG, in February 2012. Twenty-one coffee progenies were evaluated in the F5 generation and 5 commercial cultivars were used as a control. A randomized complete block design was used, with three replicates, totaling 78 plots, consisting of eight plants each. The spacing used was 3.00 x 0.50 m in the rows and between plants, respectively. The populations of M. paranaensis per gram of coffee roots, productivity (bags. ha-1 ), plant vigor, maturation cycle, maturation uniformity, coffee ranking by grain size (sieve 17 and above), and classification of mocha coffee were evaluated. It was concluded that progenies MG 0179-3-R1-151 and MG 0185-2-R2-132 are resistant to M. paranaensis and have good agronomic characteristics in an area naturally infested by this nematode, thus indicated for plantations in this situation. Nine progenies reveal tolerance/resistance characteristics to M. paranaensis.Item Sensory analysis of coffee dried with and without stirring(Editora UFLA, 2018-10) Ribeiro, Bruno Batista; Câmara, Francisco Mickael de Medeiros; Mendes, Antônio Nazareno Guimarães; Silva, Virgílio Anastácio da; Montanari, Fernanda FariaThe production of quality coffees, with different sensory characteristics, is strongly related to drying techniques. Experiments were carried out on coffee fruits, with the presence and absence of the fruit turnover process during drying, using Catuaí Vermelho 144 coffee fruits, from the Cerrado Mineiro, processed dry and wet. The treatments consisted of natural coffee, natural green coffee, pulped coffee and semi-washed coffee fruits. They were carried out in a completely randomized design, with 4 post-harvest processes, 2 types of drying (with or without Stirring) and 3 replicates, totaling 24 plots. Natural green coffee and natural coffees were more responsive in the final scores, when not stirred during the drying process, unlike the coffees obtained by wet processing. Peeled coffees obtained the highest scores for the attributes, regardless of the adoption or not of stirring during the drying process. It was possible to obtain scores above 80 points by the SCAA protocol, without stirring the coffee.
