Genetic diversity in Lilyturf germplasm detected by SRAP markers

Genetic diversity of 48 Lilyturfs from different habitats was analyzed by using molecular marker SRAP.11 effective primer combinations were filtered out and 621 bands with clearly identifiable section were amplified.Each pair of primers could amplify 56.45 bands and the number of polymorphism bands was 621.Moreover,the percentage of polymorphism loci was 100% and genetic similarity coefficient(GS) ranged from 0.058 4-0.936 7 with average value 0.497 5.These showed that the test materials were rich in genetic diversity.Cluster analysis of all materials indicated that the test materials could be divided into six groups at the genetic distance of 0.81 and some materials from the same geographical location could be classified as one group.
