Mango Glossary

Genotype is the genetic constitution of an organism. A mango seedling formed through fertilization has its own genetic combination, whereas a grafted scion normally preserves the genotype of its source tree. Genotype is distinct from phenotype, the characteristics actually observed under particular conditions. Poor flavor from immature fruit or weak growth in a saturated pot does not by itself demonstrate that a correctly labeled graft has changed genetically. Identity questions need provenance and, where appropriate, more specialized evidence.

Graft compatibility is the ability of a scion and rootstock to form and maintain a functioning, durable union. It is different from the initial appearance of callus or bud growth: a join can begin growing yet later develop weakness or poor transport between the parts. For mango propagation, use suitable, healthy material and established combinations where information is available. Compatibility does not mean that the rootstock guarantees dwarfing, disease resistance, or cold tolerance for every scion and location.
