Cultivation
Pollinator cultivar — Asian pear
Pyrus pyrifolia (Burm. f.) Nakai var. culta (Mak.) Nakai
Most Asian pear cultivars are self-incompatible and require cross-pollination to produce a crop. Key factors include the genetic compatibility of S-alleles between specific cultivar pairs and the synchrony of their flowering periods.
In the reference 10 varieties crop Asian pear, where this is mentioned in the description.
Asian pears are characterized by widespread self-incompatibility, where pollen from the same cultivar is unable to fertilize the flowers. A distinctive feature of the crop is the existence of inter-cultivar incompatibility determined by genetic S-alleles, which necessitates the rigorous selection of cultivar pairs capable of cross-pollination.
Pollination efficiency depends on the origin of the cultivars: Japanese and Chinese groups are better pollinated by representatives within their own groups due to differences in flowering periods. The use of European pear pollen as a pollinator is often ineffective due to the mismatch of phenological phases and insufficient pollen compatibility.
When selecting a pollinator, it is critical to ensure a perfect match in the mass flowering periods of the chosen pair and the pollinator's stable annual capacity for abundant flowering.
