Ploidy of rose varieties

Is there a list of the number of chromosomes each rose variety has other than help me find? I’ve noticed the ploidy of many varieties isn’t listed there.


A quick look revealed that for some the ploidy levels of the rose cultivars listed in table II of the paper are indeed not evident at hmf. With the very many other existent varieties the ploidy is unfortunately not known as determination is complex. If I find another source, I will add it.

Further rose cultivars are listed on page 15 + 16. Maybe it helps.
