Information on the genetic diversity in the target population is the basic step of each breeding program. In order to evaluate the genetic diversity of Iranian endemic coriander  16 populations, an experiment was conducted based on randomized complete blocks design with three replications in the research field of faculty of agricultural sciences, Tarbiat Modares University, Tehran, Iran in 2014. The differences among coriander genotypes were significant for all studied traits. Results of mean comparison showed that the populations NO. 160 and 353 had the highest fruit yield, essential oil content and shoot dry weight, respectively. Five factors were extracted from factor analysis, which accounted for 77.31% total variation of data. Coriander populations were categorized into four groups based on cluster analysis. Based on the proximity matrix, thpopulations NO. 230 and 306 had the maximum genetic distance also, 347 and 36 populations had the minimum genetic distance. Finally, to get more fruit and fresh vegetative yield and early ripening 450, 353, and 230 can be used in breeding programs, respectively
