Abstract: 

Genetic potential and variation of 15 Stipa arabica ecotypes collected from different regions of Iran were evaluated at Khorakian station in Qom during 2001-2003. The experiment was conducted using a randomized complete block design with three replications. Plant height, leaf, number day to germination and stem diameter were analyzed. The result of variance analysis showed that accessions are significant (p<0.05) except for node 1 and 2 interval. Correlation coefficient of plant height with other traits was positive and significant (p<0.01). Principal components analysis showed that the first three components had eigin values more than one and so entered factor analysis. Cluster analysis divided ecotypes into three groups. Ecotypes from arid region were classified in first group. Second group included several ecotypes from different regions and third group belonged to cold area.
