Abstract: 

In order to study the genetic variation of wild service (Sorbus formina/is) in Sangdeh forest of Mazandaran province, 40 indivisual trees from 2 populations were selected. From the crown of each tree, 60 fruits were by random scatered. Seven morphology and quantitical traits of the fruits and seed of these trees were studied. Data were analyzed using principal component and cluster analysis. The first two components determined 81.48% of the total variation in principal component analysis. The large diameter and the small diameter of fruits were the most important traits to make the first component. The small diameter and number of seed of the fruits were the most important traits, to make the second component. The trees were grouped into 8 cluster based on multivariate analysis of 7 classification variables. Distribution of tree based on the first two component scores was in agreement with cluster analysis. According to the results of clustering analysis and ploting of two first components, the most genetic variation observed between two populations. It was in agreement with the result of isoenzyme electrophoresis technique study, with which these two population and theirs trees were examined.
