Sweet Cherry Pollinator
Prunus avium (L.) L.
Most sweet cherry cultivars are self-incompatible, which is determined by a genetic S-allele system that inhibits pollen tube growth when genotypes match.
In the reference 349 varieties crop Sweet cherry, where this is mentioned in the description.
Self-incompatibility in sweet cherries is controlled at the genetic level, where pollen tubes with alleles identical to those of the pistil are inhibited in their growth. For effective pollination, the pollinator tree must have a different combination of S-alleles, whereas using the same cultivar or its clones is ineffective.
Key criteria for selecting pollinators include belonging to different incompatibility groups and strict synchronization of flowering periods, which must overlap by at least 70%. When planning orchards, it is important to consider that the distance between the main cultivar and the pollinator should not exceed 10–15 meters to ensure successful pollen transfer by insects.
