  • a This is not an exhaustive list: the cytotypes and crops are not strict to this table and we do not incorporate allopolyploidy events.

  • b Strawberry is an allopolyploid with autopolyploid events.

  • c Modern sugarcane cultivars are typically interspecific hibrids between autopolyploid Saccharum officinarum, Saccharum spontaneum, and other Saccharum species with varied ploidy level.
