Identification of sterile cytoplasm (CMS) in maize by using specific mtDNA primersKeywords: CMS , maize , multiplex PCR Abstract: Thirty sources of cytoplasmic male sterility (CMS) from Maize Gene Bank "Zemun Polje", distributed among Yugoslav OP varieties, have been tested for the presence of particular type of cytoplasm by a single seed multiplex PCR approach with specific primer pairs for T, C and S type cytoplasm. Combination of three pairs of primers in a single PCR reaction, corresponding to the chimeric regions of mtDNA sequences specific for each type of CMS, allowed reliable identification of the major CMS types. Dominant presence of S type cytoplasm was detected. For sources where there is no clear identification of the type of CMS (absence of the PCR band) there is a reasonable doubt that it could be a new, yet unidentified type of CMS.
