Selection of Elms Tolerant to Dutch Elm Disease in South-West Romania

Ophiostoma novo-ulmi continues to be one of the most dangerous invasive fungi, destroying many autochthonous elm forests and cultures throughout the world. Searching for natural genotypes tolerant to Dutch elm disease (DED) is one of the main objectives of silviculturists all over the northern hemisphere in order to save the susceptible elms and to restore their ecosystem biodiversity. In this regard, the first trial was established between 1991 and 1994, in south-west Romania ( Pădurea Verde , Timișoara), using three elm species ( Ulmus minor , U. glabra , and U. laevis ) with 38 provenances....
