Abstract
Pear, a pome fruit, belongs to the family Rosaceae, subfamily Maloideae and genus Pyrus. Over 20 species of pears exist around the world and all originated in regions of temperate Asia, Europe and the mountainous areas of North Africa (1–3). These species can be roughly divided into two groups, the European pears and the Asian pears. The most important edible species are P. communis (European pear and some of its related species) and P. pyrifolia (syn. serotina) (Asian pear) (4, 5). The European pears are mainly cultivated in Europe, North America, South America, Africa, and Australia. The Asian pears are mainly grown in China and Japan (1, 2). It is believed that the first species to be domesticated was P. pyrifolia, originated in China, because the wildtype is edible without selection (3). Most of the pear cultivars are diploids and have 34 chromosomes (4), but recently, triploid and tetraploid cultivars have been found in China (6). Pear can be consumed fresh or processed as perry (pear cider).
