Mutation Breeding of Oil Rose (Rosa damascena Mill)

Mutation breeding is one of the ways to create genetic variation of oil rose, as in other species. in the present study, it is aimed to develop superior mutants in terms of mophological, agronomic and quality characteristic compare to the oil rose. oil rose fruits (rosa damascena mill.) were harvested and seeds were extracted in 2007. 1000 seeds were irradiated with 0, 100, 200, 300, 400 gry doses of the cobalt 60 gamma-ray in atomic energy agency, ankara, turkey. irradiated seeds were stratified at 4°c for 3 month and planted to viols on march in 2008. seedlings applied 0, 100, 200 gry doses were transferred to pots in 2008 and were planted to field on march in 2010. mutant oil roses showed wide genetic variation for flower color (from darker pink to white), petal number (from 5 to 90) and flowering period (m1 generation) in 2011.
