Modern breeding methods such as the use of gamma rays to create genetic diversity in flowers and horticultural plants reduce the length of the breeding period and play an effective role in the development of new cultivars with superior characteristics. In the plant breeding technique with gamma rays, strategic plants with the aim of increasing variation, quality and yield, durability and marketability are considered. Rose is one of the most important horticultural crops in the world and as a cut flower has great economical value in the world. Mutation breeding is an established method for crop improvement and has played a major role in the development of many new mutant cultivars. The steps include determining the breeding target, Induced mutations with irradiating the explants (Meristem, leaves, calluses and lateral buds) and tissue culture, dosimetry, propagation, trait stability assessment, environmental compatibility, trait evaluation, selection and introduction.
