Twelve heliconia varieties were evaluated to ascertain genetic parameters of variability. Phenotypic coef-ficients of variation (PCV) were higher than genotypic coefficients of variation (GCV) for all the characters studied. However, higher PCV and GCV estimates were found for flower yield, bract size and leaf area. High heritability with high genetic advance was observed for flower yield, leaf area and bract size.
