  • Pear (Pyrus pyrifolia), belonging to the subfamily Maloideae in Rosaceae, Which constitute an economically-significant group of fleshy fruit species important for human diet, dietary diversity and ornamental beauty. The Pyroideae subfamily (to which pear and apple belong) are characterized by the pome fruits which is made up of complex fruiting organs with different expanded tissues derived from the floral tube. It have been cultivated in Europe, East Asia, and North America for up to 3000 years and is commercially grown in about 50 temperate-climate countries[1][2].
