Ulmus Laciniata - Hybrid Cultivars

Hybrid Cultivars

Several hybrid cultivars were raised as part of the Dutch elm breeding programme at Wageningen (Heybroek, 1993), crossing the species with hybrids of U. wallichiana and U. minor to produce Clone no. 560, which in turn was crossed with Clone 720 (itself a complex cross involving U. glabra, U. minor, U. wallichiana, and U. pumila) to produce Clone 1234. None of these clones has been commercially released.
