| Abstract:
Traditional pear cultivars are widely known and well accepted by consumers, thus limiting the release of new ones. Nevertheless, there is a demand for high-quality genotypes, especially in early season. Since 1968, the Forlì section of the Istituto Sperimentale per la Frutticoltura (ISF-FO) has carried out pear breeding activity, mainly focused on the selection of genotypes adapted to the Po valley environments. More than 500 crosses were performed, which produced 36,000 seedlings and 139 advanced selections. The main aims of the ISF-FO pear breeding program were as follows (major results are in parenthesis): (1) selection of early-ripening varieties (‘Tosca’, ‘Turandot’, ‘Norma’, and ‘Carmen’ released; one advanced selection developed); (2) fire blight resistance (ISF-FO 80-57-83, ISF-FO 80-51-72 and ISF-FO 80-104-72 advanced selections developed); (3) resistance to Psylla (one advanced selection developed); (4) compact growth habitus (four advanced selections for home gardens); (5) red fruit varieties (one advanced selection developed); (6) P. communis × P. serotina interspecific hybrids (2 advanced selections developed). | |
