I'd like to have one of the red limes, but politics it would seem may interfere -
There is, however, controversy over the granting of Plant Breeders Rights to some of the varieties described on this page. This is, I believe, based on the fact that some are simply selections from the best plants that have been growing in the wild. It is argued that these are not newly bred varieties, and were probably known about, and used, by Aboriginal people over many years. Click here for a flavour of these debates.
One of the consequences of granting Plant Breeders Rights in Australia, is that it becomes illegal to export the varieties. Thus these plants are not available elsewhere. However, there is no reason why similar hybrids cannot be developed. Certainly, this has already been done in USA. Click here for details. Also, export of open-pollinated seeds are not controlled, and such seeds are quite likely to produce similar plants.
