Malus ‘Datang Tingliang’: a new ornamental crabapple cultivar |
| |
Abstract: | 【Objective】 To increase the existing cultivar range and expand the categories of ornamental crabapple (Malus), we bred a new cultivar with red leaves, red flowers, and red fruits. 【Method】 We selected a new cultivar from the progeny of Malus ‘Red Splender’. 【Result】 The new cultivar Malus ‘Datang Tingliang’ expressed a single-flower umbel inflorescence. The corolla was flat. The color of flower buds changed from purple to bright red-purple while blooming, with no obvious fading. Flowers had a length of 4.5 cm with elliptical and touching petals. The tree had a columnar canopy with strong tree vigor, with tall and graceful stature. The color of young leaves was red and changed to red-green during development, and upper sides of the leaves displayed strong glossiness. The viewing period was long. 【Conclusion】 The flowers were beautiful and the leaf spread similar to a wall in spring and shadows in summer, with abundant red fruits in autumn. ‘Datang Tingliang’ demonstrates high ornamental value. |
