【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.
