). Analyses were carried on with the GLM procedure of SAS (version 8; SAS Institute, Cary, NC). Principal component analysis and cluster analysis were performed ( Sneath and Sokal, 1973 ) to classify the populations. Eight principal components were

, genetic distances were calculated according to standardized Jaccard's distance index (JDI). Both matrices were subjected to cluster analysis, one dendrogram was created for morphologic traits and another was made for the molecular data using in both cases

( Oppenheim, 2000 ). Specifically, Ward’s linkage cluster analysis has been used to identify consumer groups based on consumer behavior and sociodemographic variables ( Lessig and Tollefson, 1971 ; Zarantonello and Schmitt, 2010 ). Specific marketing efforts
