Genetic diversity in Elymus caninus as revealed by isozyme, RAPD, and microsatellite markers.

abstract：:Red clover is an important forage legume species for temperate regions and very little is known about the genetic organization of its breeding populations. We used random amplified polymorphic DNA (RAPD) genetic markers to address the genetic diversity and the distribution of variation in 20 breeding populations and c...
