Abstract
There are opportunities to develop new Limonium cultivars through interspecific hybridisation Pollination barriers exist between some, but not all, species.
Barriers include lack of pollen tube penetration of the stigma and inhibition of pollen tube growth down the style.
The pollination barrier between two species sometimes depends on which species is used as the female parent.
Post-pollination barriers (embryo abortion) also exist.
Several new Limonium hybrids have been produced using ovule-embryo rescue techniques.
Fifteen L. perigrinum x L. purpuratum embryos were succesfully rescued when L. perigrinum was the female parent.
No embryos were produced by the reverse cross.
These hybrids have flower colours intermediate between the two parents and stem lengths from 25 to 60 cm.
More recently L. perezii has been hybridised with L. sinutum. Early confirmation of these hybrids has been provided by flow cytometric analysis.
