Abstract: In this report, a simple and efficient protocol for RAPD assay in pepper was established through optimization in three main procedures DNA extraction, PCR, electrophoresis. The protocol was employed in screening RAPD markers for genetic purity testing of‘Zhongjiao’serial hybrid cultivars. A total of 12 stable and strong RAPDs were identified to distin guish all 9 F1 s from their parental lines.

Key words: Pepper (Capsicum annuum L. ), RAPD􀀁, PCR, Hybrid purity determination
