Regarding the plant "Lilium 'Pearl Jessica' Imposter" in @Australis's plant list

Australis said:Asiatic (c/c) cultivar. Doesn't match the true 'Pearl Jessica', but is likely another known cultivar that was sold into Australia. Ploidy is unknown. I am suspicious that it may be what is sold in Australia as 'Pink Flavour', but need to obtain this cultivar to check.

Here is a list of attempted cross to help determine the ploidy of the plant:

2016-2017 Season:
  • PJI X 'Navarra' (unknown ploidy) = failed
  • PJI X 'Tresor' (4N) = 7 questionable seeds + 157 chaff
  • 'Navarra' (unknown ploidy) X PJI = 16 questionable + 503 chaff
  • 'Pearl Jennifer' (4N) X PJI = failed
  • Probably 'Red Velvet' (4N) X PJI = failed
  • 'Tiger Babies' (3N) X PJI = 2 viable + 16 questionable + 637 chaff
  • 'Tresor' (4N) X PJI = failed

Originally, I was unaware that it was not 'Pearl Jessica' and so early crosses were attempted based on the assumption of tetraploidy. At this time I suspect it is probably diploid and will be trying a number of further crosses to test this hypothesis.
