Abstract
Erodium ciconium is an important grazing plant and a source of protein supplements to straw for ruminants in semideserts and wastelands of the Middle East. There is no information on its population genetic structure, genetic diversity, and morphological variability in Iran. We performed molecular data for knowing the population differentiation in this species. For this study, we used 110 randomly collected plants from 15 geographical populations in 6 provinces of Iran. AMOVA test revealed significant genetic difference among the studied populations and also revealed that, 63% of total genetic variability was due to within population diversity while, 37% was due to among population genetic differentiation. Mantel test showed positive significant correlation between genetic distance and geographical distance of the studied populations. Networking, STRUCTURE analyses revealed some degree of gene flow among these populations.

Highlights
Genetic diversity is a basic component of biodiversity and its conservation is essential for long term survival of any species in changing environments (Mills and Schwartz, 2005; Tomasello et al, 2015)
Change in environmental conditions often leads to variation in genetic diversity levels among different populations and populations with low variability are generally considered less adapted under adverse circumstances (Falk and Holsinger, 1991; Olivieri et al, 2016)
Limitations of the ISSR technique, as is the case for Random Amplification of Polymorphic DNA (RAPD; Esfandani-Bozchaloyi et al, 2019), are that the bands are scored as dominant markers and the genetic diversity estimates are based on diallelic characters
Summary
Genetic diversity is a basic component of biodiversity and its conservation is essential for long term survival of any species in changing environments (Mills and Schwartz, 2005; Tomasello et al, 2015). Knowledge of the genetic variability and diversity within and among different populations is crucial for their conservation and management (Cires et al, 2012, 2013; Meloni et al, 2015; Peñas et al, 2016; Esfandani-Bozchaloyi et al, 2018 a, b, c, d). Limitations of the ISSR technique, as is the case for Random Amplification of Polymorphic DNA (RAPD; Esfandani-Bozchaloyi et al, 2019), are that the bands are scored as dominant markers and the genetic diversity estimates are based on diallelic characters.
