RAPD-PCR Analysis on Genetic Relationships Between Cultivars of Tree Peony

<正> Random amplified polymorphic DNA (RAPD) was used to analyze genetic polymophism of 35 Tree Peony cultivars with 7 different color groups. Thirty four primers amplified 418 DNA fragments and 337 polymorphic bands (80.6%), including specific DNA markers for 18 cultivars that could be used to differentiate cultivars. The UPGMA method was used to analyze the genetic relationship among cultivars. The results
