Abstract
This research was conducted at Homand Absard research station, 70km east of Tehran, to study the establishment and survival of 10 accessions of Elytrigia libanoticus L. The experiment began in 2003 and continued until 2006. Of each accession, 25 individuals were cultivated on 13-meter lines at 50cm intervals. Cultivation lines were 75cm apart. Vigor, survival, forage and seed yield as well as growth parameters were recorded annually. The aim of the study was to determine the best accessions in view of survival and establishment. Obtained data in different years were entered in Excel and were analyzed with IRRISTAT software. Afterward, interaction effects of accessions and environment and additive main effects of the collected data were calculated using AMMI method in a randomized complete block design (RCBD). Mean comparisons were performed using Duncan's Multiple Range Test at 5% level. According to the results, there were significant differences among studied accessions at 1% level of probability during the study. Accession no. 10627 was identified as the best one while accessions 10624, 10628 and 10633 showed the lowest survival respectively
