This research was aimed to investigate the populations of Fortuynia bongei in a complete blocks design with three replications in field conditions. Treatments included the populations of Fortuynia bongei collected from Sirch, Koohpayeh, Zarand, Bam and Baghin. The traits including vegetation cover, forage yield, and seed yield were recorded. Data were analyzed by SPSS software and mean comparisons were performed by Duncan's Multiple Range Test. The results of ANOVA showed significant differences among the populations of Fortuynia bongei collected in this study. According to the results of mean comparisons, the highest percentage was recorded for the Koohpayeh population and the Bam population had the highest yield and seed production. So, these tow population could be recommended for the range lands rehabilitation projects in this area.

Preference evaluation of four species of perennial forage grasses including Alopecurus textilis L., Festuca ovina L. and F. sulcata L. and Agropyron trichophorum. In order to use for improvement and restoration of rangelands, seeds of species were collected from of Ardebil province. After seed germination test and preparing of seed bed. This eyperiment was done based on Randomized completely block design with 3 replicates in dryland conditions from 2010 -2014 in Ardabil station. After plants establishment and end of growing, crown cover Total height, seedling vigority, forage and seed production. Analysis variance of data was done using SAS software and the mean comparison with Duncan method at 5% level. The results showed that, the species in term of studied traits, had significant difference exept survival, The highest height, crown cover and forage production. Be longes to Agropyron trichophorum, The highest seedling vigority belodes to Agropyron trichophorum and Festuca sulcata finally, Therefore these con be used in improvement and developmend procces of pasture in arid and semi arid region.
