The earliest record of pear cultivation in Europe is that provided by Homer who, around 1000 B.C., wrote that pears were “one of the gifts of the gods”. By circa 300 B.C., pear cultivation was well established in Greece with distinct cultivars propagated by grafting and cuttings. France and Belgium were the main centers for pear improvement during its main developmental phase (1750–1850), where the fruit characters (with the exception of texture) found in today’s commercially grown cultivars were established. Several of the cultivars which are now among the most economically important globally [e.g., Williams’ Bon Chrétien (syn. Bartlett), Conference, etc.] developed at this time, and were derived from selections among open-pollinated seedlings of common cultivars (Vavrà and Orel 1971).
