Título:  Divergence among arabica coffee genotypes for sensory quality.

Conteúdo:  The production of specialty coffees is the main criterion to add value to the product. However, there is a lack of information regarding genetic variability of C. arabica for quality improvement. The aim of this study was to analyze the genetic divergence among Coffee arabica genotypes regarding the potential cup quality, possible limitations and their potential use in breeding programs to improve quality. We evaluated 101 coffee genotypes from the Germplasm Active Bank of Empresa de Pesquisa Agropecuária de Minas Gerais, covering different groups of genealogical origin. A randomized block design was used with two replications. Sensory analysis of the beverage was performed by two tasters per sample (repetition), using the Cup of Excellence methodology enhanced by the Brazilian Specialty Coffee Association. The attributes assessed were clean cup, sweetness, acidity, body, flavor, aftertaste, balance, overall and final score. K-means and Ward clustering methods were used to study the genotypes divergence. Based on sensory scores, the formed clusters differed with regards to all sensory characteristics (P ? 0.01). Three K-means clusters were formed among 40, 45 and 16 genotypes, with final average scores of 80.11, 83.17 and 87.56 points, respectively. Ninety percent of the genotypes evaluated have the genetic potential to produce specialty coffees. The observed divergence indicates the potential of genetic gains for quality and the Híbrido de Timor germplasm can be used for th... Mostrar Tudo

Título:  Coffea arabica and C. canephora as host plants for fruit flies (Tephritidae) and implications for commercial fruit crop pest management.
Ano de publicação:  2022
Fonte/Imprenta:  Crop Protection, v. 156, 2022.
Idioma:  Inglês
Conteúdo:  Because of the economic importance of fruit flies throughout the world, increased knowledge of alternative hosts of these pests is essential for integrated pest management in economically valuable fruit crops grown in regions where other host plant species such as coffee are also commonly cultivated. Therefore, the objective of this study was to evaluate the suitability of the cultivated coffee species Coffea arabica L. and Coffea canephora Pierre ex A. Froehner as hosts of fruit fly species in the state of Espírito Santo, Brazil, where both coffee species are widely grown in close proximity to a variety of economically valuable, and fruit fly susceptible, commercial fruit crops. Mature fruits of both coffee species were collected from 681 farms in 54 municipalities of Espírito Santo to identify the fruit fly species infesting coffee fruits and determine fruit fly infestation levels. Field and laboratory experiments were also conducted to study the relationships between coffee species and fruit fly infestation and development. Field infestation of coffee fruits by fruit flies was higher in C. arabica than in C. canephora (?Conilon?). A total of 136.7 fruit fly pupae per kg of C. arabica fruits were found, in comparison to 5.4 pupae per kg of C. canephora fruits, and 97.1% of the adult fruit flies reared from coffee fruits emerged from C. arabicafruits. Ceratitis capitata (Wied.) and Anastrepha fraterculus (Wied.) were the most common fruit fly species associated with fruits ... Mostrar Tudo
