Crossing of TB with Iris species could lead to positive effects. For 
example crossing of TB with aphylla leads to reblooming, crossing 
with reichenbachii to more robust ones for cold areas. I had a look 
at all species with 2n=24 or 4n=48 and found that melitta 
(suaveolens) could introduce new genetic material into the Iris 
flower. As far as I know it wasn't used for crossings. I myself only 
have a small garden, so I am looking for people who also want to help 
in this project. You do not have to know much but only have to have 
Iris melitta (suaveolens) in your garden. Start and cross melitta 
(suaveolens) with a modern TB. This kind of cross has one problem. 
Because melitta (suaveolens) is diploid and the modern TB are 
tetraploid, most of the seedlings will be triploid and therefore 
steril, only very few seedlings will be tetraploid and fertile. You 
can check this by looking at the polls. The triploid have only very 
few or no polls whereas the tetraploids have much more polls. So the 
first step would be to get as many seedlings as possible. Do not 
expect to get anything interesting in the first generation (F1) and 
keep all fertile plants. The interesting plants will be found only in 
the next generation (F2) when you cross the sister seedlings. Please 
also help to make this project possible.
