Landracing redcurrants

I have been collecting red currants and black currants. Usually i take cuttings only. But for a couple of years have collected different varieties.
They grow happily in differing habitats throughout my garden. I have until recently always been content taking cuttings. But since food prices rise and général interest shifts toward making your own jams and stuff, where i am at least, i need more. So i was spreading seeds of blackcurrant (cassis). Just drop the overripe berries here and there.
But that bas it’s limits too. When i had a bucket of red berries i put them in the mixer shortly and sifted the slurrie. Leaving juice and a mix of skins and seeds. So now i’ve got maybe a thousand seeds which i will direct seed into a freshly composted new bed which will have to grow next season amongst veggies.
Anybody done similar?
Tips welcome.
M’y thinking is the following. Most red currants will have low germination rates. Maybe they’ve unconsciously been selected for delivering great cuttings.
I’d like to ideally grow berries that freely cross and pop up after birds are spreading them. You know. Natural spreading currants.

Hi, I have grown red currants from seed.
Some require vernalization, that you sow them in autumn and they go through winter humid and cold. Another thing to consider, is to have an acid treatment: either send them through a stomach, or soak them in acid for some time.
Good luck!

Whats traits will you be selecting for during your landracing?

A-ha. I'd hate to eat plainly or put those seeds in yoghurt now and probably forget about it anyway afterwards. Flush... Oooops. Ha
What kind of acid? I got applecider vinegar or should i dilude HCl i got some of that..

I wouldn't know what i would select for. To me nature is pretty much perfect. There just isn't enough edible niceness.
Unwillingly i would be selecting for vigorousness and earlyness because i'd be reseeding the earliest and most vigorous well adapted growers.
People have been working on improving them for a long long time. I could have this lucky strike where i get fruits twice the size, less sour and sweeter, but i should not in any way expect that to happen. But improvements won't come if we don't try. So there is that.
I don't even really take the time to make them into something. I just hand them out to neighbors and friends. They always give something back, smiles for starters..
But yeah they'll say my uncle has much bigger berries. Then i'll ask for cuttings. Or they'll tell me where there's a région where the best grow. Or a recipe. Or they'll pop round with a pot of marmelade hoping i'll think of them next year again.
