Genetic diversity evaluation of Roegneria kamoji Ohwi germplasm from different ecoregions in China

摘要：

Roegneria kamoj i Ohwi (2n ＝ 6x ＝ 42 ) has many excellent characteristics, but little is known about its genetic diversity.The goal of this study was to identify the genetic differences among 90 specimens of R.kamoj i collected from 8 geographical groups (8 provinces, including Yunnan, Sichuan, Gansu, Xinjiang, Inner Mongolia, Ningxia, Hebei, Shanxi) in China using morphology marker ; Gliadins marker and DNA marker.We also studied the correlations between genetic diversity and five ecological factors (longitude, latitude, altitude, AMT and AMP).
