Analysis of Genentic Diversity and Population Structure in Melon (Cucumis melo L.) Breeding Materials by SSR Markers
To explore the genetic background of melon breeding materials,23 polymorphic Simple sequence repeat (SSR) markers were conducted to assess the genetic diversity and population structure among 39 melon breeding materials.71 allelic variations were detected,the average allele number and Shannon-Weaver index of each primer were 3.087 and 0.893.Genetic diversity and population structure analyses revealed that results were basically same,39 melon accessions were clustered into two groups,Cucumis melo ssp.melo and C.melo ssp.conomon.The population structure analyses revealed the genetic composition of the 39 accessions,in which 84.62％ accessions shared a likely single ancestor,and the rest were from mixed ancestors.These results had provided valuable information for breeding and exploit of new melon accessions.
