The present study aims to elucidate the agro\u2010morphological variability of coffee genotypes maintained in the National Institute of Agrarian Innovation (INIA) 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 D<jats:sup>2<\/jats:sup> 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 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.<\/jats:p>","DOI":"10.1002\/csc2.20971","type":"journal-article","created":{"date-parts":[[2023,4,4]],"date-time":"2023-04-04T19:23:35Z","timestamp":1680636215000},"page":"2877-2893","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Agro\u2010morphological characterization and diversity analysis of C<i>offea arabica<\/i> germplasm collection from INIA, Peru"],"prefix":"10.1002","volume":"63","author":[{"given":"Richard","family":"Paredes\u2010Espinosa","sequence":"first","affiliation":[{"name":"Estaci\u00f3n Experimental Agraria Perla del VRAEM, Direcci\u00f3n de Recursos Gen\u00e9ticos y Biotecnolog\u00eda Instituto Nacional de Innovaci\u00f3n Agraria (INIA) Pichari Cusco Per\u00fa"},{"name":"Estaci\u00f3n Experimental Agraria Pichanaki, Direcci\u00f3n de Recursos Gen\u00e9ticos y Biotecnolog\u00eda Instituto Nacional de Innovaci\u00f3n Agraria (INIA) Pichanaki Jun\u00edn Per\u00fa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dina L.","family":"Guti\u00e9rrez\u2010Reynoso","sequence":"additional","affiliation":[{"name":"Centro Experimental La Molina, Direcci\u00f3n de Recursos Gen\u00e9ticos y Biotecnolog\u00eda Instituto Nacional de Innovaci\u00f3n Agraria (INIA) Lima Per\u00fa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0197-6518","authenticated-orcid":false,"given":"Diego","family":"Atoche\u2010Garay","sequence":"additional","affiliation":[{"name":"Estaci\u00f3n Experimental Agraria Pichanaki, Direcci\u00f3n de Recursos Gen\u00e9ticos y Biotecnolog\u00eda Instituto Nacional de Innovaci\u00f3n Agraria (INIA) Pichanaki Jun\u00edn Per\u00fa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pedro Javier","family":"Mansilla\u2010C\u00f3rdova","sequence":"additional","affiliation":[{"name":"Facultad de Ciencias Agrarias Universidad Nacional Aut\u00f3noma de Chota (UNACH) Chota Per\u00fa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yudi","family":"Abad\u2010Roman\u00ed","sequence":"additional","affiliation":[{"name":"Estaci\u00f3n Experimental Agraria Pichanaki, Direcci\u00f3n de Recursos Gen\u00e9ticos y Biotecnolog\u00eda Instituto Nacional de Innovaci\u00f3n Agraria (INIA) Pichanaki Jun\u00edn Per\u00fa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carolina","family":"Gir\u00f3n\u2010Aguilar","sequence":"additional","affiliation":[{"name":"Estaci\u00f3n Experimental Agraria Pichanaki, Direcci\u00f3n de Recursos Gen\u00e9ticos y Biotecnolog\u00eda Instituto Nacional de Innovaci\u00f3n Agraria (INIA) Pichanaki Jun\u00edn Per\u00fa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Itala","family":"Flores\u2010Torres","sequence":"additional","affiliation":[{"name":"Estaci\u00f3n Experimental Agraria Pichanaki, Direcci\u00f3n de Recursos Gen\u00e9ticos y Biotecnolog\u00eda Instituto Nacional de Innovaci\u00f3n Agraria (INIA) Pichanaki Jun\u00edn Per\u00fa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana Gabriela","family":"Monta\u00f1ez\u2010Artica","sequence":"additional","affiliation":[{"name":"Estaci\u00f3n Experimental Agraria Perla del VRAEM, Direcci\u00f3n de Recursos Gen\u00e9ticos y Biotecnolog\u00eda Instituto Nacional de Innovaci\u00f3n Agraria (INIA) Pichari Cusco Per\u00fa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0769-5672","authenticated-orcid":false,"given":"Carlos I.","family":"Arbizu","sequence":"additional","affiliation":[{"name":"Centro Experimental La Molina, Direcci\u00f3n de Desarrollo Tecnol\u00f3gico Agrario Instituto Nacional de Innovaci\u00f3n Agraria (INIA) Lima Per\u00fa"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos A.
