Ornamental crabapple is a woody species in the genus Malus of the Rosaceae family, which has been widely cultivated for its ornamental and economic value (Wan et al. 2015; Zhao et al. 2014). It is planted mainly in temperate regions and often symbolizes good things in Chinese painting, poetry, and garden art (Guo et al. 2019). As a popular landscape plant, the ornamental value of crabapple is found in the delightful spring flowers and attractive fruit in fall and winter (Lu et al. 2015).
The book Flowering Crabapples recorded more than 1200 crabapple germplasms (Fiala 1994), among which were a large amount of pink and green leaf cultivars, such as Yellow Jade, Bride, and Molten Lava. In addition, there are many types of pink flowers in crabapple germplasms, such as ‘Fenghong Nichang’, ‘Fen Balei’, ‘Zi Dieer’, and ‘Juan Zhulian’ (Fan et al. 2019; Zeng et al. 2022; Zhou et al. 2019, 2020). However, there are few cultivars with bright-pink flowers in sharp contrast to emerald leaves. There is demand for cultivars with new and unique flower and leaf color combinations. In response to this demand, we introduce a new crabapple cultivar, Yanzhi Yu, that has bright-pink flowers and glossy leaves.
