| It also infects some citrus relatives such as Aeglopsis, Afraegle, Fortunella and Pamburus and some intergeneric hybrids. |
| An interspecific, or intergeneric, hybrid can be considered as a special form of a new species. |
| The loose interspecific or even intergeneric connections probably provide polyploids with such genetic flexibility. |
| In particular, four Citrus x Poncirus intergeneric combinations were carried out to combine the disease tolerance of Poncirus with the abiotic stress tolerance of Citrus. |
| If this is the case, it will not be possible in the case of intergeneric hybrids to determine which satisfy the exemption and which do not without access to detailed orchid genealogies. |
| The mule ducks are sterile intergeneric hybrids which are produced by crossing Pekin or Kaiya female ducks with Muscovy drakes. |
