摘　　要：多季花有髯鸢尾能在春季和秋季连续开花,花期延续至11月,丰富了秋季植物的色彩和景观,观赏价值高于普通有髯鸢尾。依据不同的花芽分化方式,可将其分为直接多次开花型、秋季循环多次开花型、生长季延长多次开花型和随时多次开花型4种类型。自19世纪末期出现多季花有髯鸢尾以来,截至2012年,在美国多季花鸢尾协会登录的品种已达到2 200个。目前育成的多季花品种,花瓣宽大,颜色丰富,多季开花特性稳定。未来可以结合作图群体建立、分子标记、遗传连锁图谱等分子方法辅助育种,缩短育种周期,减少育种的盲目性,培育出更多抗性强、观赏价值高、多季花特征稳定的有髯鸢尾。The reblooming bearded Irises refer to those bloom during spring and autumn until November. They could enrich the color and landscape of autumn,the ornamental values of which are much higher than the ordinary bearded Irises.According to different differentiation modes of floral buds,the reblooming bearded Irises could be divided into 4 categories,namely direct rebloomers,fall cyclic rebloomers,extended season rebloomers and whenever rebloomers.Since the emergence of reblooming bearded Iris at the end of nineteenth century,the number of cultivars registered on the Reblooming Iris Society of America had reached 2 200 by the year 2012.The current cultivars have wide petals,rich colors,and stable reblooming features.In the future,the breeding of Irises can be combined with the mapping populations construction,molecular markers and genetic linkage mapping to minimize the breeding period and blindness,thus generating more bearded Irises with strong resistance,high ornamental values and rebloomimg stability.
