The Rfo fertility restorer gene for the Ogura cytoplasmic male sterility (CMS) applied for oilseed rape hybrid seed production can be monitored with the use of the RAPD OPC02 1150 marker while molecular breeding. The aim of this work was to convert the RAPD marker into a more suitable SCAR marker. Total DNA was isolated from a doubled haploid line derived from the line BO20 (INRA, France). A fragment of 1150‐bp linked to the Rfo gene was PCR amplified with the use of the RAPD OPC02 primer, cloned and sequenced. A pair of primers was designed and PCR amplification was performed to develop a SCAR marker for the Rfo gene. The new marker was applied for analysis of 220 oilseed rape lines comprising doubled haploid and inbred restorer lines, restored hybrids as well as F 1 and F 2 recombinant generations involving restorer lines. Simultaneously, the RAPD OPC02 marker was used and it revealed that the markers are equivalent to each other. However, the developed new SCAR marker has made the analysis more practical, rapid and efficient.
