Abstract: | The AFLP technique of DNA analysis was evaluated as a tool for assessing genetic relationships among the cultivated eggplant,
S. melongena, and related species Solanum L. subgenus Leptostemonum (Dunal) Bitter, section Melongena (Mill.) Dunal, series Incaniformia Bitter]. Genetic distances based on the AFLP data were estimated for 49 samples of 36 distinct accessions. Phenetic trees
were constructed using Jaccard’s coefficient and UPGMA, and other clustering methods: they all had very high co-phenetic correlation
values, and were found to be consistent with previous trees based on other data types, in particular ITS-1 sequences, isozymes
and morphology, carried out on the same accessions. These results indicated that the AFLP technique is both an efficient and
effective tool for determining genetic relationships among species of Solanum. A new classification is proposed for series Incaniformia.
