Abstract
Limonium is a genus that is well known in international cut flower markets.
There has been considerable investment in breeding new varieties over many years and the objective has been to try to incorporate traits from less well known species into new cultivars. Limonium perigrinum was hybridized with L. purpuratum and a plant with stems in excess of 60 cm selected from this cross for further development. This plant was later released under PVR as ‘Chorus Magenta’. Subsequent breeding has had two aims – to increase the flower color range, but maintain the form of ‘Chorus Magenta’, and to generate a range of Limonium hybrids for the potted plant market.
There are four selections in trials as potted plants in New Zealand and Australia at present.
Limonium perezii was hybridized with L. sinuatum using embryo rescue techniques.
The hybrid plants were sterile.
Use of spindle toxins resulted in a doubling of the nuclear DNA contents of the hybrids and a large proportion of the pollen staining with Alexander’s stain.
Reciprocal crosses between the DNA tetraploids and their diploid parent species are producing embryos.
