Abstract

Geranium molle is known as Dovefoot Geranium or Awnless Geranium. Dovefoot Geranium is a low-growing herb with pink flowers and sharply toothed leaves. Dovefoot Geranium is native to Eurasia and has been introduced to many habitats of the world. This species is very similar to G. robertianum but its palmate-like leaves and bilobed petals show differences. This plant is considered to be anodyne, astringent and vulnerary. We have no information on its population genetic structure, genetic diversity, and morphological variability in Iran. Therefore, due to the importance of these plant species, we performed a combination of morphological and molecular data for this species. For this study, we used 132 randomly collected plants from 18 geographical populations in 4 provinces. Genetic diversity parameters were determined in these populations. STRUCTURE analysis and K-Means clustering identified 14 gene pools in the country and revealed isolation by distance among the studied populations. The Mantel test showed correlation between genetic and geographical distance. AMOVA revealed a significant genetic difference among populations and showed that 40% of total genetic variation was due to within-population diversity. The consensus tree of both molecular and morphological data identified divergent populations. These data may be used in future breeding and conservation of this important medicinal plant in the country.
