Molecular markers for indentifying Cytoplasmic Male Sterility (CMS) in chili pepper

Abstract

Cytoplasmic male sterility (CMS) is an inherited trait leading to functional pollen failure. It is an important trait for producing hybrid seed. For commercial chili pepper, identifying CMS elementsby the traditional method is a time-consuming process. Molecular markers are, therefore, rapidly developed to overcome this. In order to identify Vietnam CMS chili pepper, we analyzed published data to determine the possibility of using molecular markers. Results show that two elements should be used for identifying CMS pepper: (1) S and N cytoplasm, and (2) Rfand rf gene. Each element could be determined by different molecular makers. This article provides an overview ofCMS genetics for screening potential molecular markers for Vietnam CMS pepper. Also, PCR primers which could be used for future experimental research have been determined.
