Hmm, doubt I need to resort to bringing in stems. They detach pretty readily. I'll let them sit awhile. Left a bunch on the plants. It's only the couple or three easterly most clumps producing. Plants on the west end must have been too crowded. Still should be some decent genetics still. Definitely a process of adaptation going on of some kind. I bet this is enough to replace the seed I planted.

I picked some more berries yesterday from the Solanum galapagense LA 1410 that Andrew sent me my starter seed on a few years back. It went well this year I got quite a bit of seed from my ~7 plant clump which grew straight up and was self supporting. It has tiny flowers.

Andrew said he thought we should grow out the seed and distribute it. I said oh no, you would need an ounce. The thing is though you could grow far less because the seed is tiny. Some of it washes through when I try to rinse it. I bought some coffee filters but I forgot them at my parents place. Far better though to slowly rinse the seed by letting it sink and tilting the water out. Not sure how many plants you would need or how big. However I can grow an ounce of seed for a regular tomato variety with maybe ten to twenty plants normally. I suspect a similar ratio might be at play with galapagense for the same number of seeds if not the same weight.

The tiny flowers are a nuisance to work with though. Hardly produce any pollen.

I planted a few seeds the other day. Maybe in a couple months I'll have flowers and can make a cross with the four MMS x BH plants.

If not I have plenty of seed and I plan to surround an exserted stigma plant next year. Ideally a PL MMS x BH F2 but who knows?

Speaking of flowers the ones on the current plants frosted off- but the plants in main were fine. All those hairs may be mechanical frost protection. Intriguing no? The nearby plants were not fine and are about half dead.

I inspected the LA 2329 today. Picked one more berry. Have some seeds drying. Most of the first baggy I now deem not ripe but a few were. There are quite a few on the plants but I think they need some more time. They may not get it.

Still looks like maybe a couple hundred seeds from at least two plants. Interesting. Plants planted out in gardens need more space per plant than potted ones.

Very curious if any of the tomatoes planted in the LA2329 crossing block actually crossed with LA 2329. The bees behavior I observed might indicate crosses will be rare. Hopefully not none existent though! If I don't find any I will surely plant R18 G3 next to LA 2329 next year. It strikes me as having the most habrochaites like flowers of the hybrid lines. I would have this year I think if I could have tasted it in advance.

Set the sprinkler on the LA 2329 last night. Hoping it makes it through this mornings frost. Some more berries look close.

Picked the remainder of the LA2329 habrochaites berries today. Picked whole clusters hoping for some ripening off the plant. Found a few big ones. One of the biggest pictured. Suspect some are ripe or will ripen thus doubling my numbers or better from the few hundred.

William sent me ten seeds from LA2329. I grew them in a clump, in a patch with other Solanum habrochaites. They flowered profusely, and were tolerant of the early fall frosts. Some plants made fruits. Today, I extracted about 300 seeds from fruits that were collected many weeks ago. They have that trait I love in some varieties of S habrochaites of bold leaves. I love the large flowers. The bruising on the anther cones indicate that the bees do also.

The clump in the right/foreground of the whole garden photo is LA2329. The other yellow flowered plants are Solanum habrochaites, or [habrochaites X (domestic x habrochaites)]. Also in the field (not shown) was one F1 hybrid of [Brad x Solanum  habrochaites].

I put away the second and last envelope of LA2329 not long ago. It did indeed at least double what I got. A few more weeks though and it would have been thousands more.

Next year I think I'll grow ten plants of it but will give them the same amount of space. Hopefully there will also be hybrids but can't count on it for sure as it was a crossing block not deliberate crosses.

Here's a movie of the F1 interspecies hybrid that was growing in the same field as LA2329.

Extreme vigour!
I thought there would be a few F1 habrochaites show up spontaneously by now in past years but still haven't detected one! Like in 2018 when I direct seeded so much Blue Ambrosia or this year 2021 when I direct seeded a large amount of potentially crossed Big Hill Could be some in my seed collection though and could be some from the LA2329 crossing block in particular.

Your assaying of seed size to find this one was intriguing!

My thought on best practices to find that needle in a haystack seed is smaller seed plus careful propagation- direct seeding seems difficult for habrochaites in particular.
