Genetic diversity of 20 ryegrass accessions by SRAP markers

Abstract

Abstract: Sequence related amplified polymorphism (SRAP) markers were used to analyze the genetic diversity among 20 ryegrass (Lolium) lines. The results showed that 765 fragments were amplified by 53 primers. Polymorphic bands were 597 which accounted for 78.95% in the total amplified fragments. The number of amplified and polymorphic fragments was 14.43 and 11.26 per primer, respectively. The genetic similarity coefficients ranged from 0.485 to 0.727 among these ryegrass lines and the average was 0.627. Using unweighted pair-group method with arithmetic means (UPGMA) cluster analysis on the SRAP markers, these ryegrass lines could be divided into four groups by the threshold of 0.63. Two Lolium multiflorum lines could not be clustered into a group but spread in 18 Lolium perenne lines. In addition, cluster results were consistent with the resources of these ryegrass lines. All results suggested that SRAP markers were suitable for the research of the genetic diversity on ryegrass.
