Abstract© 2015, Universidad de Concepcion. All rights reserved. Tagetes erecta L. and Tagetes patula L. flowers have ornamental uses in Mexico, but also some industries used in the coloring of meat. The genus Tagetes presents species and varieties with different colors and shades in their flowers. Therefore a rapid and objective form of distinction of these varieties would be useful for the industry. In this research was developed a method to distinguish and characterize the diversity in two varieties of the T. erecta and T. patula
