Glossary

Cross-pollination is transfer of pollen between genetically different plants. For grafted mangoes, two separate trees of the same cultivar may still be the same genotype, while two different cultivars can provide genetically different pollen. Cross-pollination affects the embryo's parentage rather than changing the cultivar identity of the flesh on the current crop. It may be useful in breeding, but adding another tree does not automatically solve every flowering or fruit-retention problem.
