Popis:	Rosellinia necatrix and Armillaria mellea are becoming serious problems in several Italian sweet cherry growing areas. In February 2005, a selection study was initiated at CREA-Centro di Ricerca per la Frutticoltura, based on 550 one-year-old seedlings of commercial myrobalan rootstocks (Prunus cerasifera L.), in order to identify promising myrobalan genotypes, in terms of agronomical, phenological, and productive characteristics. After micropropagation of the 42 best-performing seedlings, 16 were grafted with commercial cultivars, 'Burlat', 'Ferrovia', 'Giorgia', and 'Lapins'. In 2010, these were planted in a field trial at the field station in Rome, with MaxMa 60 (Prunus mahaleb × Prunus avium) serving as a reference rootstock. Here, the results obtained after 7 years of observations in the field are presented. A wide range of genetic variability was identified, in terms of flowering and ripening time, growth vigour and habit, suckering activity, productivity, and qualitative aspects of the fruits. Seven selections were identified as particularly interesting; these are being further evaluated for their resistance to the above-mentioned root rot diseases.
