Abstract
Teucrium stocksianum Boiss. is one of the important medicinal plant species that is naturally grown in the Southern highlands of Hormozgan and Sistan & Baluchestan provinces, Iran. The aim of this study was to investigate the diversity of some morpho-physiological traits of different populations of T. stocksianum collected from natural habitats. The results showed significant differences among the populations for all the morpho-physiological traits. Plant height was positively correlated with plant height and width. Shoot dry weight was also positively correlated with root dry weight. Principal component analysis (PCA) showed that the first five components accounted for 84.15% of the total variation. In the first component, the inflorescence length, plant height, root dry weight, plant width, and stem dry weight were important traits (%31). Cluster analysis divided the populations into three groups and showed that the cluster analysis using morpho-physiological did not correspond to the geographical diversity. Based on the results, the populations of the second group due to having higher values for desirable traits such as large diameter, small diameter and plant length, stem and root dry weight, main stem diameter and the weight of 1,000 seeds, were introduced to breeding improved varieties.
