The knowledge of genetic diversity is essential for the efficient improvement of it in varietal improvement. This knowledge is based on the description of genetic resources. Morphological characteristics are first candidates for this description. In this context, an evaluation was then conducted to determine the morphological diversity of chili peppers in Kisangani. A total of one hundred and ninety-nine (199) fruits of the ripe chili peppers of the local varieties grown and sold were purchased at the different markets of the city of Kisangani, according to the random sampling technique. The’ set of results allowed to identify five (5) phenotypes or dominant botanical forms including: Red elongated1, Red elongated2, Red round, Yellow elongated and Yellow round. The elongated Red1 phenotype was more represented in the study population (38%), while the round Yellow phenotype was less frequent (5%). The average weight varied between 0.3 and 6.40g with a significant difference. The average length between 17.76 and 45.94 mm; the average diameter 6.28 to 31.15 mm; number of seminal boxes 1 to 4 per fruit. There was no correlation between seed box number and weight, but a fairly good correlation between seed number and weight.

Abstract: (french)
La connaissance de la diversité génétique est essentielle pour l’amélioration efficiente de celle-ci en amélioration variétale. Cette connaissance passe par la description des ressources génétiques. Les caractéristiques morphologiques sont premières candidates à cette description. C’est dans ce cadre qu’une évaluation a alors été conduite pour déterminer la diversité morphologique des piments à Kisangani. Au total Cent nonante-neuf (199) fruits des piments mûrs des variétés locales cultivés et vendus ont été achetés aux différents marchés de la ville de Kisangani, selon la technique d’échantillonnage aléatoire. L’ensemble des résultats ont permis d’identifier cinq (5) phénotypes ou formes botanique dominant dont: Rouge allongé1, Rouge allongé2, Rouge rond, Jaune allongé et Jaune rond. Le phénotype Rouge allongé1 a été plus représenté au sein de la population étudié (38%), tandis que le phénotype Jaune rond a été moins fréquent (5%). Le poids moyen a varié entre 0,3 et 6,40g avec une différence significative. La longueur moyenne entre 17,76 et 45,94mm; le diamètre moyen 6,28 à 31,15mm; nombre de loges séminales 1 à 4 par fruit. La corrélation a été nulle entre le nombre de loge séminale et le poids mais assez bonne entre le nombre de graine et le poids.
