Electrophoretic protein profiles and morphological traits were used to study the genetic diversity among accessions of Mentha spp. (M10ngifolia, M. spicata and M piperita) collected from thirty eight populations distributed in different habitats in Egypt. Ten individuals from each accession were examined for their morphological traits and the Trislborate buffer extracts of composite samples from seed meal of each population were electrophoretically analyzed on SDSIP AGE under reducing conditions. The cluster analyses of both morphological traits and protein electrophoretic criteria showed the Wlequivocal role and the jmpact of the environmental fluctuations on the genetic variations among the examined populations of Mentha. Also, the taxonomy of M longifolia was argued about the presence of two or three subspecies in the Egyptian flor |
