The diversity in the Capsicum genus and low number of ornamental pepper cultivars available have stimulate development breeding programs for this species. study segregating populations is important to obtain cultivars. objective work was detect variability a F2 population through principal component analysis (PCA) considering characters interest peppers identify which variables affect height these plants trail analysis. A crossing between two contrasting materials followed by self-fertilization F1 carried out seven were evaluated 333 generation. were: mean fruit weight (MFW), length (MFL), diameter (MFD), peduncle (MPL), pericarp thickness (MPT), plant (PH), flowering cycle (FC). results subjected using PH as base characteristic. first components explained 90% genetic population; FC together reached 96.9%; alone responsible 62.1%. showed that more affected (24.35%) MPL (16.6%); increases may increase PH. MFD presented low-magnitude negative effect on variable (-1.99%). MFW, MFL, MPT PH, 0.35%, 0.76%, 7.06%, respectively. can be explored detected evaluated, mainly Despite positively height, has magnitude.
