Abstract

Genetic diversity and relationship of 48 melon(Cucumis melo L.)germplasms were studied by molecular marker technology AFLPs(Amplified fragment length polymorphisms).Ten selective primer pairs were screened from total 64 primer pairs and 172 polymorphic bands were observed from total 423 bands.The polymorphic percentage was 40.66%.Based on AFLPs results,48 materials were clustered into two groups,ie,thick-peel melon and thin-peel melon,and the thick-peel melon was further classified into four sub-groups.The results were consistent with the traditional classification.
