Characterization of Capsicum germplasm collected in Northwestern Argentina based on morphological and quality traits
Paprika production is concentrated in Northwestern Argentina, where around 1500 ha are annually grown. Farmers mainly from Andean valleys, maintain their local landraces or “criollas” under different environmental conditions, using their farming traditions and selection criteria.

| description | Paprika production is concentrated in Northwestern Argentina, where around 1500 ha are annually grown. Farmers mainly from Andean valleys, maintain their local landraces or “criollas” under different environmental conditions, using their farming traditions and selection criteria. These traditional varieties represent valuable genetic resources for conservation and selection of agronomical and quality traits. Between 2005 and 2007 eight collecting trips were made to Northwestern Argentina in order to recover local germplasm. As a result, five hundred new vegetable seed samples have been incorporated into the Germplasm Bank. Among these accessions 32 belong to Capsicum, the majority for paprika production, that were evaluated in field conditions using a randomized block design with three repetitions of eight plants per accession; 54 morphological and agronomical traits were measured during two production cycles. Multivariate analyses determine three groups, where fruit characters were the most efficient for accession differentiation. Accessions suitable for paprika production were further examined, and variability for fruit pungency and color was found. Promising accessions were selected for ex situ conservation and breeding purposes |

En los valles andinos los agricultores mantienen sus variedades locales o “criollas” en diferentes condiciones ambientales y siguiendo sus tradiciones agrícolas y criterios de selección. Estas variedades son recursos genéticos valiosos para la conservación y selección de caracteres agronómicos y de calidad. Entre 2005 y 2007 se realizaron ocho viajes a dicha zona, con el fin de recuperar el germoplasma local. Como resultado 500 nuevas muestras de semillas de hortalizas se han incorporado en el Banco de Germoplasma. Entre ellas 32 entradas de Capsicum, la mayoría utilizadas para la producción de pimentón, que se evaluaron a campo mediante un diseño de bloques al azar con tres repeticiones de ocho plantas por entrada, y se midieron 54 caracteres morfológicos y agronómicos durante dos ciclos de producción. El análisis multivariado determinó tres grupos, donde los caracteres del fruto fueron más eficientes para la diferenciación de las entradas. Se estudiaron en particular las entradas para la producción de pimentón, encontrándose variabilidad en el picor y en el color del fruto. Las entradas promisorias fueron seleccionadas para su conservación ex situ y mejoramiento EEA La Consulta Fil: Occhiuto, Patricia Noemí. Universidad Nacional de Cuyo.
