The purpose of this study is to determine similarities/dissimilarities of rosemary genotypes and plant characteristics by different statistical methods, and effectiveness the plant characteristics on drug leaf yield and essential oil yield in Rosemary (Rosmarinus officinalis L.). Plant height, fresh leaf/fresh herb, drug leaf/fresh herb, essential oil content, fresh herb yield, fresh leaf yield, drug leaf yield and essential oil yield were measured. Data were evaluated by different statistical analyses methods such as correlation, factor, double dendrogram, biplot, agglomerative hierarchical cluster and regression. Results revealed that the essential oil content and fresh herb yield were determined as the most important parameters to be considered. When the essential oil yield is considered as the target criterion; fresh leaf/fresh herb, the drug leaf/fresh leaf, the essential oil content and the fresh leaf yield will increase success of rosemary breeding.
