The present work sought to characterize and agromorphologically evaluate 27 accessions of quinoa and the commercial cultivar \u2018Salcedo INIA\u2019 (SAL) for 28 qualitative and 25 quantitative variables. The results show that, on average, maturity occurred at 120 days after sowing (DAS), with a range of 105 DAS (ACC 50) to 132 DAS (ACC 35, ACC 37, ACC 43 and SAL). Grain diameter varied between 2.39 and 1.92 mm, with ACC 29 and the SAL control having the largest seed. The percentage of saponin varied between 0.210 and 0.089%, with ACC 43 having the lowest percentage. The severity of mildew infection varied between 17.22% and 1.22%, with ACC 50 being the most resistant genotype. Grain yield ranged from 5.60 (ACC 33) to 2.44 (ACC 42) t ha\u22121. Genotypes ACC 29 and ACC 50 had the highest selection index (SI) values, at 1.10 and 1.01, respectively, being notable for their earliness, short stature, low saponin content, and seed productivity.<\/jats:p>","DOI":"10.3390\/plants15081147","type":"journal-article","created":{"date-parts":[[2026,4,9]],"date-time":"2026-04-09T07:48:07Z","timestamp":1775720887000},"page":"1147","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Characterization and Agromorphological Variation in 27 Accessions of Chenopodium quinoa Within the Arid Coastal Zone of Peru"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-1891-5508","authenticated-orcid":false,"given":"Lady","family":"Checmapocco-Conza","sequence":"first","affiliation":[{"name":"Facultad de Agronom\u00eda, Universidad Nacional de San Agust\u00edn de Arequipa, Arequipa 04001, Peru"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fredy","family":"Huamani-Aymara","sequence":"additional","affiliation":[{"name":"Facultad de Agronom\u00eda, Universidad Nacional de San Agust\u00edn de Arequipa, Arequipa 04001, Peru"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4336-1116","authenticated-orcid":false,"given":"Alberto","family":"Anculle-Arenas","sequence":"additional","affiliation":[{"name":"Facultad de Agronom\u00eda, Universidad Nacional de San Agust\u00edn de Arequipa, Arequipa 04001, Peru"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"},{"role":"formal-analysis","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7140-3654","authenticated-orcid":false,"given":"Jos\u00e9","family":"Bustamante-Mu\u00f1oz","sequence":"additional","affiliation":[{"name":"Facultad de Agronom\u00eda, Universidad Nacional de San Agust\u00edn de Arequipa, Arequipa 04001, Peru"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7906-4845","authenticated-orcid":false,"given":"Eric","family":"Jellen","sequence":"additional","affiliation":[{"name":"Department of Plant and Wildlife Sciences, College of Life Sciences, Brigham Young University, Provo, UT 84602, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6703-6468","authenticated-orcid":false,"given":"Mayela","family":"Mayta-Anco","sequence":"additional","affiliation":[{"name":"Facultad de Agronom\u00eda, Universidad Nacional de San Agust\u00edn de Arequipa, Arequipa 04001, Peru"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"75","DOI":"10.15381\/quipu.v25i47.13805","article-title":"Per\u00fa Como Primer Exportador de Quinua a Nivel Mundial","volume":"25","author":"Soria","year":"2017","journal-title":"Quipukamayoc"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1","DOI":"10.26788\/ri.v12i1.4398","article-title":"Caracterizaci\u00f3n agron\u00f3mica y morfol\u00f3gica de las accesiones de quinua (Chenopodium quinoa Willd) obtenidas ancestralmente v\u00eda descriptor bioversity international","volume":"12","author":"Sucasaca","year":"2023","journal-title":"Rev.
