We have been lied for too long, Daubenton can produce flowers, and thus can be cross pollinated, and have been ! Here are some crosses i am aware of.
Here is a message from Graham. D. Jenkins-Belohorska our beloved super-admin, about Daubenton crosses :
Daubenton x Late Purple Flowering Broccoli, by Stephen Barstow
source
Summer 2013, I grew about 25 plants from the cross and the following pictures show the mix of plants that resulted...most were tall like the broccoli but a few were low growing like Daubenton, but grew poorly as shaded by the taller plants. Several were sprouting wildly low down on the plants, hinting at perenniality?
(Daubenton x curly kale) x Brussels Sprouts, by Lieven David
Don't expect perennial Brussels sprouts, but (Daubenton x curly kale) x Brussels Sprouts cross is fun to grow & eat. Quite diverse & cuttings root pretty easily.

After reading about daubenton kale I managed to obtain two cuttings that today are two big plants in my veggie garden, after a drought period one of these two plants flowered and having Lacinato kale near it the easiest bet was to use it as pollen parents, after some tentative pollinations the daubenton produce some pods and after some time mature seeds(around 20 seeds)
I've skipped a season and in winter time sowing my pepers I found the seed again and planted it, I've ended with two promising seedling that I've planted near the daubenton for possible backcrossing in future
...
One plant looks like it has a more elongated growing habit and the second has larger leaves and a more bush habit ,I've tried to propagate the two plants via cuttings and it works fine! we will see what happens next spring in order to flowering non flowering habit
...
I've to see that I'm very happy if the two clones especially the large leaves one show good perenniality, it taste great for my family, the taste is a bit more "delicate" tan the Lacinato that tastes strong and is grown by everybody here, and produces lots of tender new shots that are the best part of the kale

Daubenton X Red Kale, by Graham. D. Jenkins-Belohorska
source1 - source2
[F2 Daubenton X Red Kale self seedlings] Most look a bit of a mess at the moment as they are in flower, but there is some interesting segregation going on amongst this group. The plant that isn't flowering is probably my best bet for recovering a red Daubenton type as it has yet to flower and is looking pretty bushy, but only time will tell for sure. The F1 from this cross are still going so perenniality is expressed quite strongly in this line
F2
Daubenton X Tree Collard, by Graham. D. Jenkins-Belohorska
I've made a few bud pollination to self this plant, and they look to have taken, so hopefully I can recover something a little more compact from this cross.
Here is a message from Graham. D. Jenkins-Belohorska our beloved super-admin, about Daubenton crosses :
I don't claim to be an authority on the subject, but I can offer some observations:
Firstly, Daubenton has passed on it's perenniality to all the F1 seedlings I've grown from it so far (though some are longer lived than others). So I'd tentatively say that perenniality is a dominant homozygous trait in Daubenton. There may be some other genes in the seedlings that influence the longevity of the plants, but I cant be certain if they came from Daubenton or the biannual parents. But if they are from Daubenton it's heterozygous for these regulators.
The inheritance of perenniality in the F2 more or less follows the mendelian ratios for dominant inheritance, so I'd say you could safely discard any biannual material.
The non flowering (or infrequent flowering) habit appears to be recessive as the F1 plants from crosses to biannuals flower annually after their second year.
As for the inheritance of anthocyanin expression, Daubenton will express anthocyanins in crosses with red Kales. And it appears to lack any of the regulatory genes that restrict where anthocyanin is expressed.
In the crosses with tree collards there was a split between green and purple veined seedlings, but I suspect that was due to the tree collard being heterozygous for anthocyanin production. I made this cross in both directions and the results are pretty similar regardless of the direction of the cross. There were a higher percentage of green seedlings overall, but the population size was to small to draw any real conclusions from that.
The branching habit of Daubenton is passed on to its seedlings, but it's expressed to a lesser extent (fewer duds break to produce branches). It could be that it's a polygenic trait or a dominant trait with an additive affect, I cant really say for sure (though I suspect it's the latter).
Overall, I'd say Daubenton is fairly homozygous for most traits. When I've crossed it with other brassicas the results have been fairly uniform, and most of the variation I have seen I'd largely attribute to the other parent.
As I say these are just my observations, so don't take them as gospel. But they may prove useful if your fortunate enough to have Daubenton flower for you.
