Variability study of agro-morphological characteristics is important for varietal improvement and plant breeding program. For this, 148 chili pepper landraces (Capsicum annuum L.) collected from Northern Benin were characterized using 39 (21 qualitative and 18 quantitative) morphological characters. The trial was conducted in a Fisher block design with 3 replicates at the experimental station of the Faculty of Science and Technology (FAST) of Dassa based in Central Benin. The results revealed considerable morphological variability between landraces. Twenty nine (16 quantitative and 13 qualitative) variables among the 39 examined were discriminatory and group the landraces into 4 classes when considering the qualitative variables. With quantitative variables, 9 groups were obtained. The correlations between the studied quantitative variables show that the yield parameters are correlated with the variables related to the vegetative part of the plant. This study will help breeders to better select their parents for crossing in order to produce desirable and high yielding varieties.
