| Abstract: | This paper deals with the pollen, morphology of 5 parent plants and 3 F_1 hybrid seedlings during breeding of new cultivars for establishing a Rejuvenation Rose Group. They were examined under SEM. Most pollens of Rosa xanthina and Rosa cv. Goldilocks are not viable and can not be used as paternal parents. So are some F_1 seedlings. Pollen grain surface patterns can be differentiated between parents and their F_1 seedlings. F_1's differ from their parents in exine ornamentation. But,all species and cultivars of Rosa are similar in the gross morphology of their pollen grains. |
