摘要
采用扫描电镜,对刺玫月季育种中使用的5个杂交亲本和3个F_1杂种花粉,进行观察和研究。通过对花粉形态的比较研究,讨论花粉败育对刺玫月季育种的影响,及亲本与杂交种在花粉外壁纹饰上的相关性。
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.
