[Objective]The present experiment was conducted to study the genetic diversity and relationship amongst different water chestnut (Eleocharis tuberosa Schulut) cultivars to provide reference for breeding water chestnut. [Method]Random amplified polymorphism DNA (RAPD) molecular markers were used to assess the genetic diversity amongst 24 water chestnut (Eleocharis tuberosa Schulut) cultivars using RAPD primers and cluster analysis was performed. [Result]Out of 100 primers, 15 primers with clear bands and pol...
