Abstract
The second pandemic of Dutch elm disease (DED), caused by Ophiostoma novo-ulmi, had devastating effects on Iberian field elm (Ulmus minor Mill.) stands. In order to mitigate these effects, the Technical University of Madrid and the Spanish Environmental Administration initiated the Spanish Elm Breeding and Conservation Programme (SEBCP) 27 years ago. Since then, research performed by the SEBCP has obtained many results that have aided the protection and recovery of this emblematic and cultural species. Among the most important achievements we highlight the discovery of seven Iberian U. minor clones with high degree of resistance to DED. These clones have recently been registered in the Forest Reproductive Material National Catalogue as ?qualified clones? for their use and marketing. The breeding programme has also obtained other genotypes with promising degrees of tolerance to DED in their initial susceptibility trials. The SEBCP obtained low rooting success rates (10-20 %) when trying to propagate elm clones with traditional vegetative propagation techniques. Since this limited the production and distribution of valuable elm genotypes, the programme has now focussed on micropropagation. This technique enables increasing elm clones? multiplication rates and achieving rooting rates of over 60 %, with the additional advantage of only requiring small quantities of initial material.
