Intervarietal F1 hybrids of Fritiliaria thunbergii and interspecific F1 hybrids between F. thunbergii and its kindred species were successfully obtained. The methods of breaking the dormancy of F1 seeds and F1 bulbs were investigated. Moreover, the temperature off-season generational advance was preliminarily grouped.
