A:PS

The aim of this study was to formulate a classification for coefficients of variation of experiments with Capsicum to be used in six morphological fruit variables. We selected 38 trials with published results using data on morphological characterization of fruit and coefficients of variation (CV) of the following response variables: average fruit weight, fruit length, peduncle length, smallest and largest fruit diameter and pericarp thickness. The CV classification ranges were based on the methodology proposed by Garcia (1989), which considers the property of the normal distribution of CV. All variables met the assumption of normal distribution of CV by the Lilliefors test at 5% probability. The CV classification ranges obtained for these six variables were distinct from those of the general classification proposed by Gomes (2000). Moreover, it was found that ratings of the coefficients of variation of morphological variables of pepper belonging to the genus Capsicum depend on the response variable, and the largest CV classification ranges were for smaller fruit diameter, pericarp thickness and average fruit weight.
