Development of Gene-Based Markers for The Pun1 Pungency Gene in Pepper (Capsicum spp.) for Marker-Assisted Selection

 Summary: Pungency in fruits of pepper (Capsicum spp.) is due to the accumulation of capsaicinoids. Pun1 is an important gene responsible for pungency. To provide information for marker-assisted selection (MAS) of pungency, we developed and evaluated five codominant markers based on sequence of the Pun1 gene. The usefulness of these gene-based markers for pungency in MAS was tested using 85 pungent and non-pungent lines and cultivars. Our results demonstrated that these markers can discriminate the pungent and non-pungent genotypes. Our results show that the five gene-based markers could be useful as a marker-assisted selection tool.
