crossing the ploidy boundary

15 years ago

Hi All,

I haven't posted here in quite awhile but still lurk off & on.

In fall 2009 I posted some questions about crossing the ploidy boundary in hybridizing without the use of colchicine.

I just wanted to give an update that in 2010 I tried the recommendation to cross tetraploid pollen onto h. fulva 'Europa' (triploid) in order to make tetraploid offspring.

I pollinated every open bloom on a large clump of fulva for 3 consecutive days, using the same pollen parent.

This resulted in 7 seeds and two of those proved viable and have become healthy seedlings ready to harden off & plant outdoors. Of course I'll have to keep them alive for at 2-3 years before I see what they look like but I'm excited at the prospects.

The pollen parent is 'Red Suspenders' which is a good performer here, blooms early & long with very large, clear red, UF flowers & decent branching. I'm hoping for something red, uf, early and with the drought tolerance, vigor, & scapes of 'Europa'.
