Abstract

Abstract: Study on genetic diversity of watermelon could benefit the research of cultivar property right p rotecting, seed purity testing, and genetic breeding. A new molecularmarker system-SRAP ( Sequence-Related Amplified Polymorphism) was firstly app lied on 20 watermelon hybrids genetic diversity research. 20
primer pairs selected from 25 amplified 135 polymorphic bandswith an average of 71.1 polymorphic bands per primer pair. Cluster analysis using UPGMA method based on the data of SRAP amplified bands by 20 primer pairs showed 20 hybrids could be distinguished into three main groups. Jaccard's similarity coefficient ranged from 0.29 - 0.86.

Key words: Watermelon, Hybrid, Polymorphism, SRAP
