ABSTRACTThe level of polymorphism in chili was studied using ISSR marker. Polymorphism of sixteen chili varieties was evaluated with 15 ISSR primers. These 15 ISSR primers have generated 136 DNA bands, 102 being polymorphic, with an average of 9.06 bands per primer. The evaluation of the dendrogram obtained by UPGMA allowed the differentiation of all the varieties. Four varieties were separated in distinct group in which showed complete correspondence to its observed characters. DNA profile of 16 chili varieties based on ISSR marker revealed the potential of digital fingerprints of all varieties examined.
