Fruits of the pear variety 'Boscs bottle pear'

'Boscs bottle pear' (synonyms: often 'Kaiser Alexander', and more rarely 'Calebasse Bosc', 'Kaiserbirne', 'Alexanderbirne' and in Northern Germany 'Kaiserkrone' ) is an old pear variety .

history

The origin of the variety is unclear. Either it was bred by the Belgian pear grower Jean-Baptiste van Mons around 1807 and came from him to Adrian Diel in 1810 , or it is a chance seedling that was found as a tree near Apremont in 1793 .

Bosc's bottle pear was named after Louis Augustin Guillaume Bosc and Hadrian Diel referred to it as Emperor Alexander , probably after Alexander I. In the 1920s, Bosc's bottle pear was one of the three pear varieties that were chosen as imperial fruit varieties .

The fruit is medium to large with a height of 9–11 cm and a diameter of 5–7 cm, and is pear- to club- or cup-shaped. The rough skin has a greenish-yellow basic color, which is mostly completely rusty yellow-brown. The fine flesh is yellowish, sweet and sour and juicy with a fine aroma.
