  • Tidbit
  • There are only two commercially grown cultivars of banana in the world today; Musa acuminata 'Dwarf Cavendish' and Musa acuminata 'Grand Nain'. They are referred to as the Cavendish banana (which is from the AAA Group). They are seedless and must be propagated from suckers. As a result they are the most sprayed crop in the world because they are all genetically identical and disease spreads rapidly between them.
