This study was performed to select marker which can identify genetic variation between mother plant and in vitro cultured plantlets of strawberry by PCR using random primer. When 'Yeobong' DNA extracted was treated with proteinase-K and RNase-H, clear DNA bands were shown. The optimal condition for RAPD in strawberry was to use 50ng of template DNA, 10pmol of primer,37oC of annealing temperature, and 45 cycles of PCR. After establishing above PCR optimal condition, RAPD pattern was investigated by using UBC primers. PCR was performed, and 46 of 90 primers produced PCR product showing 158 total bands. GC content was compared between the primers forming bands and no bands. The GC content showing bands was average 67.4%, whereas primers showing no bands 58%.
