Since blackcurrants and gooseberries cross (jostaberries) I'm wondering whether red/white currants and gooseberries might cross. Perhaps the route might be red currant crossed with a jostaberry (already a hybrid) then onto gooseberry. I'm interested in mixing these up. A gooseberry sized red currant would be a delight.

Having killed many currant and gooseberry plants on my too-climatologically-rigorous farm, my desire to grow them remains unsatisfied; I think I may be able to coax some along when I have more time on-site. Meanwhile, can somebody work on crossing them with brome, which grows really well there?

Ray,
the wikipedia entry for Jostas indicates they are tetraploid, Deppe states equal chromosome numbers for all the parent Ribes (2n=16), I assume the parents are diploid. So, would a tetra cross with a di?
Since the original cross was done with black currants given the chromosome numbers are the same for red currants, i assume the cross is possible. Wiki also indicates use of colchicine in development of Josta. Looks like a project.

Meanwhile, can somebody work on crossing them with brome, which grows really well there? I've never had luck with either of these for similar reasons, I presume. A drought hardy tasty juicy Ribes, that's what i want. T |

Yeah, damn! Why can't I grow things that I really want regardless of their climatological needs? Aren't these lesser species subject to my rule? I thought that was the deal. Did I not get the memo on a corporate restructuring, cosmologically?

meanwhile, they grow great here (wild ones in the woods, etc) but are outlawed by the state...

Still outlawed? I thought they were pardoned ~12 years ago.

Is it because of white pine blister rust (or whatever it was), or just legislative inertia?

Is it because of white pine blister rust (or whatever it was), or just legislative inertia? That is the disease... but I think the second factor is more significant for that far south. |

There are plenty of other more doable crosses that I could occupy my time with. |
