Plant Breeding / Re: legal status of many varieties investigated
« on: 2019-01-15, 09:38:42 AM »
Yeah, I've signed a few material transfer agreements myself, and I will need to go back and look in more detail,  but half of them were very loose and can be interpreted multiple ways that they may have loop holes. I honestly didn't feel restricted at all,  so I was fine with them. Each place has different terms.

I found this podcast from the TED radio hour very interesting on this topic.

The Bifurcatedcarrots blog is run by Patrick. He used to be very active on the old Alan Bishop Homegrown Goodness forum.  He is an American who moved to Europe. He is a pretty cool guy from what I remember. He probably is a member on this forum already, but i wouldn't know.

I think he is anti GMO as I seem to remember many comments about things in Europe and people destroying Corn fields over there. But I could be misremembering. Perhaps his old blog posts were just reporting on it.


After I took this photo, comparing the typical small peruvianum fruits to a larger peruvianum fruit, I found a plant that had even larger fruits.... When I grow tomatoes 9 inches apart, it's hard to pay attention to individual plants, until something grabs my attention. Larger fruits certainly did. I saved seeds separately from larger fruited plants, and am intending to do early selection next year by culling plants with small fruits early in the season so that they don't shed pollen for small fruits into the patch.

That's way cool!

That reminds me of another idea I had once. I suspect just growing plants next to each other that epigenetic influence can occur from chemicals leached into the soil.

One year I grew a whole patch of my purple stalked corn. That year and the following year after (maybe two) the grass weeds turned a heavy red shade. It did not seem like a coincidence. Obviously they couldn't have been influenced by pollen. It made me wonder if grinding up dessert adapted plants like yucca and spraying it on as fertilizer could help produce a more desert tolerant domestic crop like corn.


I'm wondering if something as simple as refrigerating a ripe tomato fruit for a month prior to harvesting the seeds could trigger an epigenetic change towards more cold tolerance. Or how about freezing the fruits before extracting seeds?

I think it could be a very good technique. I've thought about it myself. In fact,  it would be nice if we could artificially have a chilled room that was cold but not freezing at the times of growing we wanted to induce an epigenetic change (which I suspect over time epigenetic change can induce more permanent genetic changes), but over several generations.  This I suspect that line would grow better in such conditions.

Simply planting seeds early direct seeded might select naturally for early frost/cold tolerance,  but late cold/ frost tolerance might be a whole separate set of genes or epigenes.

There is a very interesting thread on Tomatoville,    'Mountain Gem' F1 hybrid tomato,  started by RandyG,   Dr. Randy Gardner
from North Carolina, who bred a lot of the tomatoes with "mountain" in their names.

I'm ordering these two right now based on flavor!! The podcast interview was amazing!! Modern resistance + heirloom flavor!

? As of today, they are still not commercially available. But we want you to try them out. So here’s the deal. If you will donate $10 to support new variety development, we’ll send you packets with 15 seeds each of Garden Treasure, Garden Gem and our newest variety that we call our "W" hybrid. The W Hybrid has been shown to have a much higher than normal lycopene content.

EDIT: oh, these might be different than the 'Mountain Gem' above.  I guess I saw the word "gem" and thought they were the same.

. The horrible-flavor conferring u gene would be at worse heterozygous, and invisible because recessive.

Haha,  I like that you call the u uniform-ripening gene as the "horrible-flavor gene" ;)

So true. One of my best tasting tomatoes,  'Anasazi' has green shoulders and I think it tastes amazing. It even won a taste contest a few years ago tieing with 'pineapple' I think. But it does have some sort comings such as cracking and splitting and someone who tried it last summer said he thought it tasted insipid. Lol. I guess everyone has a different idea of what a good tomato tastes like. Some like acid, some like sweet. Some like complex. I have a feeling that color not only affects flavor by chemicals,  but also affects perception which affects flavor in one's mind.

Regardless I really am on the lookout for tomatoes that have green shoulders and do not have the uniform ripening gene as it really does have a big affect. No more cardboard tomatoes for me!

Hello Chiu-Ki Chan! Yep, that's me. Lol.  Welcome to the forum! I still live in Loveland, but next summer I might move to Fort Collins to pursue a degree in plant breeding at CSU.

Hi Klaus! Good to see you here!

Plant Breeding / Re: Books about plant breeding

Tsitsin's book "wide hybridisation of plants" looks great. Sad that not all of it is scanned. Do you know of anyone having a book scanner?

Otherwise, I would chip in to help paying for a scan with a commercial scanner like this

Any one interested enough to help chip in some money to try that book scanning service above for an electronic copy of the wide hybridization book? I think i'm willing and ready to do it if anyone else is interested.

EDIT: i'm not sure if it is still copyrighted. It was published in 1962, but I don't know if the copyright was renewed or not.

Plant Breeding / Re: Potential for Open Source BT Eggplant

Yes, I would probably agree. Maybe if the pests are so bad you can't grow any at without it, then maybe.  But I don't necessarily think one should grow it just because. And while this particular trait may be safer than i originally thought,  i do wonder about environment leaching and whether other insects or organisms are affected without intention.

I wonder if BT Eggplant isn't too simple of a trick though. If the pests become resistant than back to square one.

True.  I imagine it will happen sooner or later. Especially with how many other BT Crops are out there. In fact I thought the might already be BT resistant corn borers already... maybe?..

Plant Breeding / Potential for Open Source BT Eggplant
« on: 2019-01-03, 12:45:39 PM »
A new variety of engineered BT eggplant has no restrictions on saving seed or using in plant breeding and is currently considered an open pollinated variety. The potential to use this variety to breed and release an open source version should be possible.

I neither support or discourage anyone from this,  I just wanted to share the possibility. I am not philosophically opposed to bioengineered plants or foods, though i am often highly sceptical of each one individually. I try my best not to judge broadly. But I don't see any inherent mutually exclusive thing about open source and bioengineering.

I don't currently grow eggplant or plan to right now,  so I won't be growing this variety at this time. episode 166

166 – Two Critical Updates – Brinjals and Chestnuts

This week’s podcast features and update on two critical technologies– the Bt Brinjal (eggplant) in Bangladesh and the blight resistant American Chestnut. Both of these were covered in earlier episodes, and an update on...

A long time ago I got one my best pea varieties from a Canadian company, at that time they still shipped to the U.S., i believe they stopped because of not wanting to fill out customs information. If there was another reason i don't remember. But I've gotten tomato seeds from canada since then in envelopes.

When I request seeds from foreign seed banks they always put something like "seeds for scientific purposes" or some variation on that theme. When i send seeds internationally i pretty much do the same on my customs declarations. They seem to make it fine. I figure that if it is for plant breeding then it is perfectly accurate and truthful.

When shipping to AU I've started trying to mark things with specific Latin scientific names and looking over non allowed lists. But I've only just started doing that.

Feral radishes eh? How fun! I should try that. Problem is, that grasshoppers are ferocious predators of radish seed pods in my garden. Hmm. Sounds like it's finally time to get some chickens out there.

There is a wild radish plant that grows here off and on. It is all over the city.  A weed I guess. I don't know where it came from but it has some spicy seed pods. Maybe I should collect seeds for it and cross it with some other radishes bred for large seed pods. These have little purple radish flowers.

OSSI pledged varieties / Re: Breeding Goldini Zucchini Podcast

Where is the best place to get seeds for the Goldini Zucchini?

I read there is little seed to share right now?

Yes, I planted them mixed. The second largest may well be domestic. Neither tasted that great, not bad, but not good enough to eat the whole thing. I just ate a few scoops from each.

I'm almost certain the big one is partly citron, due to the patterns and pale flesh.

Cool! Thanks for the grow report and collaboration!
