The exploitation of peppers is oriented by their characteristics, namely and first the pheno-morphological ones. Those of peppers from the Haut-Sassandra region (Côte d’Ivoire) are poorly described. In order to establish them, 18 accessions were characterized from eight quantitative parameters in a five-repeat incomplete random block trial. The analyses revealed accessions with opposite and similar characteristics. Thus, the accession Bec d’oiseau collected in Zoukougbeu, with a long germination period (9 days), good growth and good vegetative development, the largest leaf area (26.61 cm2), is it the most different accession of the 17 others. Also the accession Inconnu collected in Daloa stood out with the shortest time to germination (5 days), good growth and vegetative development, the second highest plant height (23.02 cm), but low lateral growth and leaf area. Likewise, the accession Bec d’oiseau from Issia stood out with the longest time to germination (10 days), average growth and development. The other 15 accessions formed a cluster, with a relatively short to relatively long time to germination (6-8 days), relatively slow growth and vegetative development. This study showed the existence of an important pheno-morphological diversity within the 18 accessions of peppers studied. Time to germination, plant height and leaf area were particularly discriminant of these accessions. The characteristics of these peppers can be exploited in breeding.
