Standard type chrysanthemums have some important agronomical characters to be improved; such as reducing axillary buds for save the farmer's labor, and flowering in low temperature to save the cost of heating. Chrysanthemum (cv. Jimba) leaves were cultured on MS medium for plant regeneration, and irradiated ion-beam. Then, the regenerated nursery plants were cultured in two different seasons in December and/or March cropping systems. The two strains individually selected in 2001 were proliferated by vegetative propagation. We succeeded in the introduction of two new cultivars of standard type chrysanthemum with reducing axillary buds in 2003 by using ion beam irradiation. The numbers of axillary buds of them were less than half or quarter, compared to the original cv. "Jimba". They were named "Aladdin" and "Imagine". The number of petals of "Aladdin" is more than that of "Jimba".
