| description | The selection of a suitable cultivar as a seed source for rootstock production can be considered of great importance since the success or failure after the plantation establishment depends on the attributes of the material used as a pattern in the production of seedlings. This research aimed to characterize morphologically and physiologically different creole cultivars of avocado to identify elite materials that can be used as rootstocks. The research was carried out in Supia, Caldas - Colombia (5°26'39'' N; 75°38'56'' W). A completely randomized experimental design was used with 17 treatments (accessions) and 20 replications. The variables evaluated were rootstock stem diameter, rootstock height, leaves number, leaf area index (LAI), specific leaf area (SLA), dry matter, net photosynthesis (A), stomatal conductance (gs), transpiration (E), and water use efficiency (WUE). The largest records were for rootstock stem diameter ID08, ID-06 (˃ 9 mm), rootstock height ID01, ID-15 (˃ 60 cm), leaf area ID08 and ID15 (> 2000 cm2), LAI ID14 (1.99), SLA ID06 and ID17 (164.23 and 167.57), total dry matter ID01, ID08, ID15 (43.50, 42.91 and 42.80), A: ID01 and ID02 (˃6 μmol CO2 m-2 s-1), gs: ID-16 (0.15 mol H2O m-2 s-1), E: ID-16 (5.93 mmol H2O m-2 s-1) and WUE: ID02 (1.70 μmol CO2/mmol H2O) accessions. The origin of the avocado cultivars significantly influenced physiological and morphological behavior, thus enabling the detection of early attributes for selecting materials that can be used as rootstocks. |

La selección de un cultivar adecuado como fuente de semilla para la producción de porta injertos se considera de gran importancia para el establecimiento de un cultivo, ya que el éxito o fracaso después del establecimiento de la plantación depende de los atributos del material utilizado como porta injerto en la producción de plántulas. Esta investigación tuvo como objetivo caracterizar morfológica y fisiológicamente diferentes cultivares criollos de aguacate para identificar materiales élite que puedan ser utilizados como patrones para la producción de plantas injertas de aguacate. La investigación se realizó en Supía, Caldas-Colombia (5°26'39'' N; 75°38'56'' O). Se utilizó un diseño experimental completamente al azar con 17 tratamientos (accesiones) y 20 repeticiones. Las variables evaluadas fueron diámetro del tallo del patrón, altura del patrón, número de hojas, índice de área foliar (IAF), área foliar específica (AFE), materia seca, fotosíntesis neta (A), conductancia estomática (gs), transpiración (E) y eficiencia en el uso del agua (EUA). Las accesiones que mayores valores presentaron fueron para: diámetro de tallo del patrón ID08, ID-06 (˃ 9 mm), altura del patrón ID01, ID-15 (˃ 60 cm), área foliar ID08 e ID15 (> 2000 cm2), IAF ID14 (1,99), AFE ID06 y ID17 (164,23 y 167,57), materia seca: total ID01, ID08 ID15 (43,50, 42,91 y 42,80), A: ID01 y ID02 (˃6 μmol CO2 m-2 s-1), gs: ID-16 (0,15 mol H2O m-2 s-1), E: ID-16 (5,93 mmol H2O m-2 s-1) y UEA: ID02 (1,70 μmol CO2/mmol H2O). El origen de los cultivares de aguacate influyó significativamente en el comportamiento fisiológico y morfológico, lo que permitió detectar atributos tempranos para seleccionar materiales que puedan ser utilizados como porta injertos.
