Evaluation of the experimental coefficient of variation of pepper traits

The aim of this study was to formulate a classification to coefficients of variation experiments with Capsicum for use in six morphological variables of the fruit. We selected 38 trials with results published in which data consisted of morphological characterization of fruit and coefficients of variation (CV) of the response variables: average fruit weight, fruit length, peduncle length, highest and lowest fruit diameter and thickness of pericarp. The CV classifications ranges were based on the methodology proposed by Garcia (1989), which considers the property of the normal distribution of CV. By Lilliefors test at 5% probability, all variables met the assumption of normal distribution of CV. The CV classifications 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 the genus Capsicum pepper depend on the response variable, and the highest classification bands for CV were smaller fruit diameter, pericarp thickness and average fruit weight.
