Irises have high ornamental values because of their decorative flowers and the elegance of their elongated leaves (Roguz et al., 2020; Xu et al., 2017). For example, Iris sanguinea has a blue flower color that offers great potential for landscaping. It also has strong disease resistance, and is cold and moisture tolerant (Bi et al., 2011; Shang and Wang, 2014). Thus, it could be widely used for gardening and landscaping in northeastern China. These factors have encouraged the development and release of new iris cultivars. Recently, new cultivars with various flower colors have been developed and released by crossing I. sanguinea with I. sanguinea f. albiflora, which has a white flower. These include cultivars NEFU-1 (Qi et al., 2020), Zi Meiren (Chen et al., 2019), and White Skirt (Wang et al., 2019).
We developed a new cultivar, Qihuan Zi, via a cross between I. sanguine and I. sanguinea f. albiflora. The flower of ‘Qihuan Zi’ is multicolored, which is obviously different from both parents and previously released genotypes.
