摘要

In this research, eco-geographical effects on genetic diversity of Elymus tauri populations from northwestern of Iran were investigated by utilization of RAPD markers. The genetic diversity within and among populations were estimated by using Analysis of Molecular Variance (AMOVA). The AMOVA analysis based on eco-geographical regions revealed that the inter-regions genetic diversity was 13%, whereas, the intra-region genetic diversity was 87%. The lower genetic diversity and also lower level of polymorphisms in Mishow region compared to Sabalan region, are due to lower altitude, and also early grazing and overgrazing.
