Accessions of peppers and sweet peppers (Capsicum annuum) of Embrapa Clima Temperado genebank (Pelotas - RS) integrate Capsicum genetic resources. However, it is necessary to know how much these genotypes are different, so they can be harnessed and used in breeding programs. The aim of this study was to evaluate and characterize genetic diversity among C. annuum accessions which belongs to Capsicum Embrapa Clima Temperado genebank. Twenty accessions were characterized through 36 multicategorical morphologic descriptors. Genetic diversity was assessed using Tocher grouping method and UPGMA. Three groups of accessions were formed by Tocher. Both methods were in agreement with the isolation of P77, due to its exclusive morphological traits. The study shows moderate genetic variability among 20 accessions of C. annuum studied and introduced accession with ornamental features, which can be incorporated in breeding programs.
