Genetic diversity among alfalfa (Medicago sativa L .) cultivars using ISSR markers
The cultivated alfalfa is an autotetraploid and allogamous species (2n ＝4x ＝ 32).Alfalfa germplasms are invaluable genetic resources for improving and breeding the alfalfa cultivars.Due to the allogamous behaviour, much genetic variation exists in the alfalfa germplams.Obviously, it is very necessary to evaluate the genetic diversity and relationship among the alfalfa cultivars through molecular markers analysis.The inter‐simple sequence repeat ( ISSR) is a kind of molecular marker which exhibits the length polymerphism between two microsatellite loci.In order to provide new insight into the genetic diversity and relationship of alfalfa germplasms, 30 accessions of Medicago sativ a from China and other four countries were investigated by the technique of ISSR.
