Coffea arabica L. belongs to the Rubiaceae family, and the genus Coffea is believed to have a primary center of origin and genetic variability in the highlands of southwestern Ethiopia. It is a vital beverage commodity across the world and a valuable export product, ranking second in international trade after petroleum. Ethiopia is among the top five major coffee-producing countries and is Africa’s leading producer. However, its full production capacity has not yet been exploited, and research efforts to reduce biotic and abiotic factors through reproduction have been extremely limited. Hence, improvement through different breeding methods is essential to overcome the constraints in its production. Thus, the objective of this study is to review the different breeding methods applied for different traits in Ethiopia. Breeding methods depend on the type and the source of traits and the final breeding objectives. The main breeding objectives are production, resistance/tolerance to diseases, and cup quality. The commonly applied breeding methods are selected and intra-specific hybridization, germplasm enhancement, and the development of improved varieties with wider adaptability. There is also a practice of crossing parental lines selected for certain desirable traits for the development of hybrid varieties. Accordingly, some promising success has been obtained. Forty-one coffee varieties have been released so far. Because conventional breeding methods are time-consuming, integrating conventional breeding methods with biotechnological techniques could have an instrumental role in the rapid development of suitable varieties for the changing climate.

Caracterización agronómica de 95 accesiones en el banco de germoplasma de café en Chanchamayo (Perú), año 2016 Agronomic characterization of 95 accessions in the bank of germplasm of coffe plant in Chanchamayo (Peru) year 2016 L. Alvarado, R. Vértiz, J. Jiménez, R. Borjas, V. Castro y A. Julca Universidad Nacional Agraria La Molina, Lima, Perú Recibido el 14 de junio del 2017. Aceptado el 19 de julio del 2017 DOI: https://doi.org/10.33017/RevECIPeru2017.0004/ Resumen El presente estudio tuvo como objetivo evaluar las características agronómicas de 95 accesiones en el banco de germoplasma de café (Coffea arabica L.) en Chanchamayo, año 2016. Este trabajo se llevó a cabo en el fundo “La Génova” de la Universidad Nacional Agraria La Molina en San Ramón-Chanchamayo. La caracterización se basó en caracteres que describan la capacidad productiva de la planta y su comportamiento frente a la “broca” (Hypothenemus hampei) y “roya” (Hemileia vastatrix). Luego se realizó un análisis de varianza y una Prueba de Duncan para cada variable estudiada mediante el programa Statgraphic. Se realizó un análisis multivariado (componentes principales y agrupamientos) con el programa NTSYS que permitió conocer los caracteres que han expresado un mayor grado de variabilidad, así como la relación entre accesiones. Las accesiones con más altos rendimientos en promedio de café cerezo/planta fueron UNACAF-70 con 5.42 kg/planta y UNACAF-149 con 4.16 kg/planta; mientras que las accesiones menos sobresalientes fueron UNACAF-151 con 0.22 kg/planta y UNACAF-223 con 0.15 kg/planta. Con respecto al peso de café pergamino seco por planta, la accesión más sobresaliente siguió siendo UNACAF-70 con 1.1 kg/planta. Finalmente, los caracteres más discriminantes fueron peso de café cerezo, peso de café pergamino seco, número de frutos por planta, peso de pulpa de 100 frutos maduros y peso de 100 frutos maduros. Descriptores: café, broca del café, roya del café, análisis multivariado. Abstract The present study aimed to evaluate the agronomic characteristics of 95 accessions in the coffee germplasm bank (Coffea arabica L.) in Chanchamayo, in 2016. This work was carried out in "La Genova" fund of the National Agrarian University La Molina in San Ramón-Chanchamayo. The characterization was carried out on the basis of characters that describe the productive capacity of the plant and its behavior against the "drill" (Hypothenemus hampei) and "rust" (Hemileia vastatrix). An analysis of variance and a Duncan test were performed for each variable studied using the Statgraphic program. Then a multivariate analysis (main components and groupings) was carried out with the NTSYS program that allowed to know the characters that have expressed a greater degree of variability, as well as the relation between accessions. The accessions with the highest yields in average coffee cherry / plant were UNACAF-70 with 5.42 kg / plant and UNACAF-149 with 4.16 kg / plant; While the least outstanding accessions were UNACAF-151 with 0.22 kg / plant and UNACAF-223 with 0.15 kg / plant. Regarding the weight of dry parchment coffee per plant, the most outstanding accession remained UNACAF-70 with 1.1 kg / plant. Finally, the most discriminating characters were cherry coffee weight, dry parchment coffee weight, number of fruits per plant, pulp weight of 100 mature fruits and weight of 100 mature fruits. Keywords: coffee plant, coffee berry borer, coffee rust disease, multivariate analysis.
