Abstract

Abstract: Study on genetic diversity of Marigold could benefit the research of cultivar property right protecting，seanged purity testing，and genetic breeding. A new molecular marker system-SRAP (Sequence-Related Amplified Polymorphism) was firstly applied on 48 marigold hybrids genetic diversity research. 20 primer pairs selected from 60 amplified 289 polymorphic bands with an average of 14.45 polymorphic bands perprimer pair. Cluster analysis using UPGMA method based on the data of SRAP amplified bands by 20 primer pairs showed 48 hybrids could be distinguished into two main groups. Jaccard s similarity coefficient ranged from 0.25-0.91.

Key words: Tagetes erecta L., Hybrid, Polymorphism, SRAP
