    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 Alves
    The 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.

    Adaptability and stability of organic-grown arabica coffee production using the modified centroid method
    (Crop Breeding and Applied Biotechnology, 2017-10) Moura, Waldênia de Melo; Oliveira, Ana Maria Cruz e; Gonçalves, Débora Ribeiro; Carvalho, Cássio Francisco Moreira de; Oliveira, Rebeca Lourenço de; Cruz, Cosme Damião
    This study aimed to identify promising arabica coffee genotypes for organic systems. The experiments were arranged in a randomized block design, with 30 genotypes and three replications. The adaptability and stability analysis was carried out using the modified centroid method, considering the mean yield of two biennia (2005/2006 and 2006/2007, 2007/2008 and 2008/2009) in three municipalities (Araponga, Espera Feliz, and Tombos), totaling six environments. Significant genotype x environment interaction was observed for yield, and the municipality of Espera Feliz was the only favorable environment. Genotypes were classified into four of the seven groups proposed by the modified centroid method: maximum general adaptability (I), minimum adaptability (IV), mean general adaptability (V), and mean specific adaptability to favorable environments (VI). Cultivars IBC Palma 1, CatucaíAmarelo24/137, Sabiá 708, and H 518 are widely adapted, stable, productive and suitable for organic farming. Remove selected
