Parental choice is key step in breeding programs. Better results are obtained when, in the base population a large genetic variability is combined with high traits means. The objective of this work was to estimate means, heritability and genetic diversity among eight Capsicum annuum ornamental lines to predict the potential of these accessions as genitors. Data were subjected to analysis of variance and means were grouped by Scott-Knott criteria at 5% of probability. Estimates of heritability; coefficient of genetic variance (CVg), and coefficient of environmental variance (CVe) were obtained. Mahalanobis Distance, Tocher's and canonical variables analysis were used to evaluate genetic divergence. The importance of variables to the genetic variability was determined by the Singh's method and canonical analysis. CVg/CVe ratio indicated greater importance of genetic variation in relation to environmental variation. Heritabilities ranged from 70% to 99.87%. Based on means and on Tocher's and canonical variables methods, the crossings UFSJ 7 x UFSJ 4, UFSJ 7 X UFSJ 5, UFSJ 7 X UFSJ 6, UFSJ 6 X UFSJ 4 and UFSJ 6 X UFSJ 5 are recommended. Dry matter fruit content and days to flowering contributed least to genetic divergence and should be suppressed in future works. Leaf length and width contributed most to this estimate.
