Abstract
For evaluation and identification some of the chamomile species in two genera Anthemis and Matricaria, morphological and phonological characteristics were used. The experiment was conducted in a Randomized Completely Blocks Design (RCBD) with three replicates, sixteen quantitative and qualitative traits were evaluated such as plant height, anthodium diameter, receptacle diameter, ligulae flower number, dry flower percent, 100 flower weight, time of flower beginning, yield, flower number per plant, 1000 seeds weight, stomata length, leaf length, leaf width, flower color and type of leaf and receptacle in 26 genotypes. Results showed that genotypes were significantly different for all traits. Principle Components analysis (PCo) analysis placed 16 traits in five principle components that covered 91 percent of variance. The first principle components covered 39 percent of variance included main traits such as anthodium diameter, receptacle diameter, ligulae flower number, 100 flower weight, yield, 1000 seeds weight, leaf length. Cluster analysis classified genotypes to 8 main groups and 2 independent genotypes. This study showed that morphological markers on of the reliable mean to determined genotypes and species, yet.

Abstract
Genetic diversity of German chamomile (Matricaria chamomilla L.) populations in Iran was evaluated using morphological, agronomical and phonological characteristics and compared with three cultivars from Germany, Hungary and Iran. In this experiment, statistical design of RCBD with three replications was used, sixteen quantitative traits were measured such as yield, flower number per plant, anthodium diameter, receptacle diameter, 100 flower weight, essential oil percent, pollen diameter, stomata length, leaf length, leaf width, seed weight, vegetative period, height, generative period dry flower percent and ligulae flower number in 26 populations. Results of variance analysis showed that populations were significantly different for all traits except stomata length. Result of simple correlation analysis showed significant positive and negative correlation among many traits. Vegetative period duration showed significant negative correlation with most of traits. PCA analysis placed 16 traits in three factors that covered 78.89 percent of variance. The first factor, that in fact is Yield and yield components factor, covered 58.46 percent of variance included main traits such as height, yield, flower number per plant, anthodium diameter, receptacle diameter, 100 flower weight, 1000 seed weight and ligulae flower number. Cluster analysis classified populations to 3 main groups and 2 independent populations. Groups mainly have differences in yield and yield components. In this investigation many native populations were similar or better than cultivars, having cultivation potential or breeding programs.
