Message:
Abstract:

A significant area of the country's rangelands is degraded due to various factors and an important part of rangeland species is endangered or their population is severely reduced. Rangeland improvement and reclamation through selecting suitable species and finding the best cultivation methods are of utmost importance in these rangelands. Therefore, according to the results of the research project performed in the Research Institute of Forests and Rangelands, the seeds of Sa.arbuscula were collected from different rangelands of Semnan province along with the existing populations. The study was conducted in a randomized complete block design with three replications at Semnan Research Station since 2011 for five years. The data were analyzed using SAS software and the means were compared with Duncan's test. Our results clearly showed that among the study accessions of Sa. arbuscular, the genotypes 230 and 234 with an establishment percentage of 86.67% and 84.02% were superior, respectively. Therefore, the genotypes 230 and 234 could be recommended for rangeland improvement and reclamation.
