‘Kalliopi’ is a mid- to late July maturing pear cultivar originating from a cross between the local Greek pear cultivars Kristali and Kontoula. Fruit are obtuse–pyriform to nearly turbinate with equatorial diameter ≈50 mm, fruit length ≈45 mm, and fruit weight ≈121 g. Productivity of ‘Kalliopi’ was lower than ‘Coscia’; however, yield efficiency of the two cultivars was not different. Total soluble solids and firmness of ‘Kalliopi’ were higher than ‘Coscia’, whereas total titratable acidity was not different among the cultivars. The flesh is yellow–white, juicy, sweet–flavorful, and fine-grained with very few stone cells (scleroids). The skin is green, blushed red with sun exposure, smooth, free of russeting, and has no tendency to become waxy in storage. Fruit ripens on the tree in mid- to late July, and a selective harvest of three picks is required. The fruit flavor is sweet. After harvest, fruits can be kept at room temperature for ≈1 week or they can be refrigerated (1 °C) for 1 month after which time internal breakdown tends to occur.
