【 摘 要 】

68 accessions from the Capsicum collection of the Colombian Corporation for Agricultural Research (Corpoica), Palmira were morphologically characterized by using 12 quantitative and 10 qualitative descriptors. For the principal components analysis the variables with highest contribution were associated to plant architecture and fruit descriptors and their explained 70.8% of total variability. Classification analysis based on quantitative data showed 5 groups but did not allow discrimination between species. For the multiple correspondence analysis 83.4% of the variability was explained by variables related with flower and fruit traits. The classification analyses using qualitative descriptors showed 4 groups and allowed discrimination of C. baccatum species. The discriminant analysis showed that C. annuum, C. frutescens, and C. chinense are phylogenetically closely related.
