Landscape is more importance, especially in urban areas. Among broad-leaved trees the plane (Platanus sp.) has major role in establishing landscape areas. This tree belongs to Platanaceae family. The geographical distribution of this genus includes from east mideterranean regions to northern America and Groenlands. Among Platanus species it is expected that only the P. orientalis would be native to Iran. With respect to plane importance in urban landscapes, prior to found and select elite genotypes or varieties the evaluation of possible differences in according to morphological and genetic characteristics among plane trees of various regions is necessary. For evaluation of genetic diversity among and within plant populations, morphological studies are one of the useful methods. In this respect, for evaluation of parameters such as number of lobes per leaf, leaf shape, succulent rate, number of fruit and dropping pattern of bark, the samples of P. orientalis from Isfahan, Arak, Karaj, Mahallat, Kashan and Natanz and also tow samples of P. occidentalis , were collected. Among and within species relationships of studied planes were drawn by using data those were obtained from morphological characteristics. For this purpose, Jaccard’s similarity coefficient and UPGMA algoritm with cophenetic correlation coefficient of 0.846 has been used, that indicating suitability of UPGMA method for sample justify; MARGIN: 0in 0in 10pt" Keywords : Plane, genetic diversity, morphological characteristics , SRAP marker, Iran
