As grown at NCGR-Corvallis, the foliage and distinctive spreading growth habit appear identical to several clones of Sorbopyrus. The fruit size is intermediate between Sorbopyrus CIGC 28 (from Washington Park Arboretum) and several large fruited clones. The phenotypes of PI 506381 and PI 506382 appear to be identical. -- J.
