In order to shortening of propagation time and limiting the sucker formation in grafted roses and also study the different propagation methods and rooting media, a split plot experiment with three replications was used. Main plots consisted of two types of rooting media and subplots were 3 propagation methods of Rosa hybrida 'Baccarat' by grafted cuttings (stenting) on two dogwood roses R. canina , R. canina 'Inermis' or by cuttings. The results showed that disinfection with sodium hypochlorite solution at 1 to 9 dillution can caused blackening some parts. It seems that the using of bottom heat system and fine water mist system is necessary for implementing this method. Mixture of sand and peat in equal proportions was the best media rooting percentage and rooting rate (p ≤ 0.01). Mean comparisons showed that R. canina rootstock have more rooting percentage and quality (length, number of roots), callus formation and rooting rate than R. canina 'Inermis'. there were significant correlations only between rooting percentage and callus formation (r = 0.887 ***) , root numbers and rooting rate (r = 0.507 *). Key words: Grafted cutting, , Rooting, Rootstock, Rosa hybrida, Stenting
