Abstract

To evaluate range species including Elymus transhircanus, Stipa bromoides, Stipa capillata, Koeleria macrantha, Koeleria phleoides, Melica cupani, Melica jacquemontii with several accessions, this research was conducted at Homand Absard Rangeland Research Station to select the best accessions. The experiment began in 2003 and continued until 2007. After seedbed preparation, accessions were planted on 13-meter lines with a distance of 75 cm.

Measured variables included: forage yield, canopy cover, plant height, seed yield, number of flowering stems, leaf density, vitality, basal area, and canopy diameter. Data were analyzed by SPSS and mean comparisons were performed by Duncan’s Multiple Range Test. According to the results, Melica jaquemontii showed priorities in forage yield, basal area, canopy cover, and canopy diameter compared to other species. Meanwhile, accession 10714 was recognized as the best accession from the mentioned species. Also, the highest number of flowering stems and seed yield, leaf density, vitality, and plant height were recorded for accession 10708 (Melica cupani), accession 10683 (Koeleria macrantha) and accession 10795 (Stipa capillata), respectively.
