Introduction Oxytropis ochrocephala is one of the most hazardous locoweed species distributed extensively on grasslands of western China.Furthermore,it is becoming invasive by replacing local forage grass species in natural grassland plant communities.Understanding the genetic structure of invasive plants is important in elucidating their evolutionary history and migration route,and help in explaining the success of invasiveness and predicting its expanding potential.
