Coffee (Coffea arabica L.) plays a major role in the economy of Peru and the world. The present study aims to elucidate the agro-morphological variability of coffee genotypes maintained in the INIA´s germplasm collection. Therefore, 20 vegetative, reproductive, and phytosanitary traits of 162 coffee accessions of INIA’s germplasm collection were evaluated and analyzed. Correlation results indicate that a simultaneous selection of characters, such as number of branches per plant, number of nodes per branch, leaf area and weight of a hundred fruits, can contribute to increase coffee yields. Additionally, coffee yield was negatively correlated with the incidence and severity of coffee leaf rust, and interestingly the occurrence of small and compact coffee plants with high resistance to the disease was also found. The analysis of Tocher and Mahalanobis D2 determined the formation of 10 groups of divergent coffee accessions; where clusters 1 (accession codes 20, 29, 38, 54, 67, 71, 117, 24, 26 and 27), 5 (accession codes 46 and 53), 9 (accession code 159), and 10 (accession code 203) group promising accessions that can be used in breeding programs. Principal component analysis (PCA) showed that at least five of its principal components managed to explain 70.01% of the total variation in the collection. Finally, the high coefficients obtained for the phenotypic, genotypic and heritability variation confirm the existence of additive genes in the evaluated population, that would ensure the success of coffee breeding programs based on the selection of traits of agronomic importance.

El café es una bebida de las más conocidas del mundo y es un producto agrícola muy valioso de exportación, siendo el de mejor calidad el café Arábica, que representa aproximadamente el 70 % de la producción mundial del café (Anthony et al., 2001). Los primeros documentos en el siglo X, atribuían propiedades medicinales al cafeto, descrito por primera vez por Al Razi, un médico árabe de la época, quien mencionó sobre sus granos y sus propiedades estimulantes como “excelentes para combatir la melancolía” (Fisac-Pedrajas, 2014). El café posee una mezcla de más de 800 compuestos complejos y volátiles con cualidades antiinflamatorias, antioxidantes y antibióticas. Los ácidos clorogénicos y la cafeína son los componentes más conocidos. Asimismo, contiene vitamina B3, potasio y magnesio (Cano-Marquina et al., 2013). El Perú se ubica en el noveno puesto como exportador de café a nivel mundial, alcanzando una producción de 4 millones de sacos de 60 kg, que equivale al 2 % de la producción del mundo (United States Department of Agriculture [USDA], 2025). Según la Junta Nacional del Café (JNC, 2023), se estima que la producción de café comprende aproximadamente 425 000 hectáreas cultivadas e involucra a 230 000 familias peruanas. El Banco de Germoplasma del INIA incluye una colección de 169 accesiones de café obtenidas de las principales zonas cafetaleras del país y conservadas en la Estación Experimental Agraria Pichanaki (Chanchamayo, Junín). Este catálogo presenta 150 accesiones de dicha colección, con sus características más relevantes, con el objetivo de dar a conocer los avances en la caracterización agromorfológica y contribuir a la identificación de accesiones promisorias potencialmente útiles para programas de mejoramiento genético.

Characterization of the horizontal resistance of coffee (Coffea arabica) to yellow rust (Hemileia vastatrix) in the field and laboratory
(The American Phytopathological Society, 2022-03-25) Paredes Espinosa, Richard; Mansilla Córdova, P. J.; Abad Romaní, Yudi Gertrudis; Gutiérrez Reynoso, Dina Lida; Guerrero Abad, Juan Carlos; Egoávil, G.
Between 2011–2013, yellow rust unleashed one of the most important phytosanitary crises in the coffee sector in Peru, causing a negative impact on the rural family economy. One of the factors associated with the intensification of the disease was the predominance of susceptible cultivars in agricultural systems. Faced with the need to rehabilitate the coffee park with new cultivars, the National Institute for Agrarian Innovation (INIA) has managed the installation of basic coffee germplasm for the development of the yellow rust resistance program, which is made up of 169 introductions from the departments of Pasco, Junín, Huánuco, Ucayali, Cajamarca, and Amazonas and obtained from 2015. The objective of the study was to evaluate the incidence and severity of epidemic conditions in the field and characterize the components of horizontal resistance, using the method of inoculations of H. vastatrix in separated coffee leaves in the laboratory. The epidemiological results collected from the field indicate that 12.43 and 20.71% of the genotypes showed complete and incomplete resistance, respectively; 66.86% showed high susceptibility to the pathogen. Three of the outstanding genotypes gave a typical horizontal resistance reaction when artificially inoculated with uredinospores on separated coffee leaves kept in a humid chamber.

Las accesiones 66, 174 y 226 tienen potencial para instalarse en zonas de alta infestación L. coffeella, ya que, podrían ser opciones viables en programas de manejo integrado de plagas enfocadas en el uso de variedades resistentes que consecuentemente contribuirán con la disminución del uso de insecticidas y conservación del medio ambiente.
