Nettle is one of the important medicinal plants especially in the North of Iran, which is so far a comprehensive study on this plant in Iran. The present study was designed to investigate the variation of morphological traits in three populations Nettle in Golestan province based on two-factor factorial experiment in a completely randomized design with two factors of region and gender in three replications. The samples were taken of both male and female sexes in the north (Naharkhoran, Gorgan), West (Aliabad) and East (Bandar Gaz) of Golestan province. Based on the variance analysis, nettle samples showed significant differences based on region, gender and their interactions in most of the studied traits. Based on the mean comparison of traits in different regions, except for plant height and node numbers in the main stem, three locations placed in two different groups. In the case of all other characteristics include the leaves number, leaf area, total weight and plant dry weight was considerable variation between three regions, and the plants of the Naharkhoran region performance to a higher intensity than the other two regions. Male plants also significantly have imported a considerable performance yield than female plants. So Naharkhoran region of Gorgan has suitable climate for cultivation and dissemination of nettle. There were samples with high quality and diversity of morphological traits in this region that can be used by researchers for breeding programs.
