Cultivation
Pollinator cultivar — Asian pear
Pyrus pyrifolia (Burm. f.) Nakai
Most Pyrus pyrifolia cultivars exhibit gametophytic self-incompatibility controlled by S-alleles, which necessitates mandatory cross-pollination for the formation of a marketable yield.
In the reference 13 varieties crop Japanese pear, where this is mentioned in the description.
For successful pollination of Asian pears, it is necessary to consider the presence of group incompatibility, in which certain cultivars are unable to effectively fertilize each other. The genetic division of the crop into Chinese and Japanese groups leads to significant gaps in flowering times, which in most cases precludes the possibility of their cross-pollination.
The European pear Pyrus communis is not a reliable pollinator for the Asian pear due to significant differences in vegetation periods. In commercial orchards, it is recommended to select cultivars from the same geographical group with coinciding flowering phases or to apply artificial pollination with pollen from a compatible cultivar.
