L. pimpinellafolium x Bonner F1 and F2

[dustdevil]

When you grow a thousand plants of somebody else's "lines" without written permission to do so, are you expected to pay royalties? I ask because a thousand plants seems to be a commercial undertaking for profit and not so much a "test" bed.

These are TGRC accessions of S. pimpinellifolium, provided to breeders for just this kind of purpose - to identify potential useful traits within "wild" lines containing genetic diversity not found in cultivated tomato. The Tomato Genetic Resource Center is a non-profit entity that exists to encourage exactly this sort of activity. Good luck Darrel.

No-shows so far are: LA0530, LA1910, LA1994, LA1261, LA1582, LA1689, PI306814. Everything else that i planted came up as at least one and most of the time 4 or more plants.

There is still a chance they might germinate, some of the seed in these trays is just starting to pop through.

Dusty, 1000 plants is barely a scratch on the surface when screening for relatively rare genetics. If I only find 5 plants that can be used for breeding, then I will call it a resounding success. If I get 50, it will be successful beyond my wildest dreams.

Frogleap, I have quite a few seedlings of the FLF. What size fruit should I expect from it?

about ping pong ball size

I put the germination trays on top of the fluorescent lights for a day where the temp is about 85 degrees. Now I have germination on all except LA1261 and LA1994. There is still time for these to grow. Just from scanning the trays, it looks like I will have around 750 plants to set out, quite a bit lower than the thousand I had hoped for. Germination on these seed is erratic at best. I planted 7 or 8 seed for each accession. On average, I might have 4 plants per. Some are represented by a single plant. We will see!

Wow Darrel you were able to get that skanky PI seed of the S.peruvanium F? to germinate. Good for you! I'm planting this week and will watch out for LA1994.

[Fusion_power]

Frog, The key is very very shallow planting, temps of 75 to 80, and very careful watering. 1/8 inch deep is the most they can grow out of. I'm covering them with about 1/16 inch of powdered promix BX.

Here are a few more that might be interesting. Haven't researched them, just did a brief scan.

I got germination on LA0530, but the seedlings are really, really small. Two more I found could be interesting are LA2533 and LA722, do you have either of these?

[Fusion_power]

I grew LA2533 in my greenhouse last year and saved quite a few seed. I have maybe 50 plants growing in one of my seed trays for this year.

I don't have LA0722. It is interesting because it is a readily available source of viroid resistance. Maybe I can get some seed and grow it in the greenhouse this fall.

I did not get germination from any of the LA1994 seed.

Update that I potted up all of the TGRC and PI lines today. I got one small plant from LA1994 and one from LA1910. There were quite a few that germinated a few plants very early, then waited up to 2 months and then germinated several more seed. I had one variety that was a total no-show until about 10 days ago, then sprouted a dozen plants.

Way to go Darrel. I'm anxious to learn from you observations this year.

[Fusion_power]

I had several interesting observations in the process of potting up the seedlings.

Of the S. Pimpinellifolium plants, several showed high susceptibility to phytothora.

Of the S. Peruvianums and crosses, root strength was very high in a few. One variety was so tightly clumped that I broke a seedling trying to pull apart the clump. This could be an interesting trait to pursue since it seems to be tied to a very large root system.

Several lines showed prostrate growth habit.

A few lines showed extreme vertical growth habit.

The frilly frond-like leaves of some of the S. Chilense are very ornamental.

Update that I planted all of the breeding lines today. My garden runneth over!

I'll do an inventory tomorrow and put the layout in a spreadsheet. For the time being, the cell trays with labels are still sitting beside the plants.

I saved a few LA2533 just in case I need some extras.

I'm delving into the background of the varieties I grew this year. So far, I can't find info on one marked PI 1568259. This may be a misspelling and should be PI 568259.

Of the S. Pimpinellifolium's that I started I have plants in the ground for all of the core collection.

Interesting genes represented include SW-7 from LA4442, an unknown Late Blight resistant gene in LA2533 (may be PH3), Early and Late blight resistance from LA2093 (may be PH2), high soluble solids, high sugar (LA2086), jointless (LA4026), and a large number of septoria tolerant lines including several S. Peruvianium and S. Chilense accessions along with hybrids of Peruvianum X Lycopersicum.

There is one very interesting gene in LA3126 which is supposed to be a Septoria tolerant line. All of the lower leaves on the plants have turned nearly white indicating chlorophyll has been retrieved from the leaves leaving only the upper whorl of new leaves with green color. The white leaves are still completely healthy. There is something genetic going on in this line that I have not seen previously. This trait is highly likely to be involved in the Septoria tolerance.

Here is the complete breeding list. Keep in mind that I have about 400 more varieties that I can use for crosses if needed.

Darrel - it was a typo PI 568259 =[L.peruvianum (128655) x Bonny Best]F5. I can't wait to see what you find this summer.
