|discussion=<p><i>Malus prunifolia</i> is closely related to the cultivated apple, <i>M. domestica</i>, and sometimes is used as rootstock for the latter because of its extensive root system. <i>Malus prunifolia</i> differs from <i>M. domestica</i> in having more sharply serrate leaves, glabrate or glabrous abaxial surfaces of mature leaves, relatively long pedicels, and pomes with raised, swollen, fleshy-based sepals.</p><!--
--><p><i>Malus prunifolia</i> is cultivated worldwide and utilized as grafting rootstock, as a fruit tree, and as an ornamental. The species is potentially a genetic source of cold tolerance and disease resistance for apple-breeding programs. See discussion under 4. <i>M. fusca</i> for distinguishing <i>M. prunifolia</i> from the hybrid M. ×dawsoniana.</p><!--
--><p><i>Malus</i> ×scheideckeri Späth ex Zabel is considered a hybrid of M. floribunda and <i>M. prunifolia</i> (see discussion of the latter under 8. <i>M. halliana</i>). The 'Scheidecker crabapple' is cultivated as an ornamental tree for its semidouble pale pink flowers and yellow to orange globose pomes.</p>
