The genus Capsicum belonging to Solanaceae family enjoys favorable conditions for successful development in the Colombian Amazon. Five accessions of the Germplasm collection of Amazonian Capsicum of the Institute SINCHI were selected for their high pungency to study the growth, development and the effect on the patterns of interception of photosynthetic active radiation (PAR), production and quality of fruits under three planting distances (50, 60 and 70 cm between plants). For this purpose, an experiment was conducted in field conditions in Florencia, Caqueta.
