SUMMARY
RAPD markers were used to characterize 26 Rosa genotypes, of which 17 were obtained in Romanian breeding programs. All of the twenty decamer primers yielded scorable amplification patterns and generated polymorphic bands among the genotypes studied. RAPD is therefore a reliable procedure for distinguishing among Rosa cultivars and also for assessing the genetic similarity among different genotypes useful in breeding selection programs. This work is the first of its kind reported in Romania.
