I tend to stay away from facebook groups myself, but there probably are some good garden groups on there. I have also noticed all garden forums going south lately too. This is really the only good one left in my opinion. The tomato centric forums seem to still have lots of people, but i'll be honest in saying that a forum that is 90% dedicated to one crop seems weird to me. Despite the weird vibes i get from them sometimes i've started to visit them a little more and am venturing into tomato growing this year. Still one has be careful to not step on anyone's toes in those places or you may inadvertently see the "tomato nazis" show themselves. (no offense intended to anyone who may be lurking about). Having said that, there are plenty of nice people on there with lots of knowledge and willing to share seeds. So a big thank you to all those people. Most of the good gardening places i visit these days tend to be random blogs. I will do my best to try and track them down and post them here. As has already been mentioned though is agro.biodiver.se ,which i second as a fantastic plant breeding news outlet.

It's currently snowing again. Here goes round two for cold temperature / frost tolerance selection for early germinating landrace watermelon...

Could it be the same as what they do for seedless grapes? My understanding of seedless grapes is that they are neither GMO or chromosome mismatch like in seedless watermelon, but instead spray they unfertilized grapes with gibberellins or some chemical to make them grow. I had heard this also makes them slightly elongated in the process.

Does that mean then the intermediates are pure breeding tall and the tallest are heterozygous? When they hit full size count them up - and if you want I'll run them through a chi square stats package. I think F2's are pretty vigorous from what I've seen - but I believe it's related to overall heterozygosity not just the Le/le locus. Cheers Steve From what i understand it's at least a possibility. Without genetic testing i'm not sure how you actually find out unless you do lots of measurements and follow the offspring closely. Perhaps if you measured the pure tall parent line as a control base line you could figure it out. But i think your right, hybrid vigour may be related to the overall genetic heterozygosity and not just for one locus.

keen101 (Biolumo / Andrew B.) Interesting about the intermediate offspring. There are I think at least 5 recognized genes that only function in the presence of le. I seemed to have three different heights segregating in one cross - I just assumed I had one of the other genes in the mix. I suppose you could always check the numbers and run it through a chi square. Steve, another alternate explanation is that assuming you had a perfect mendelian trait of tall vs dwarf that in addition you were also observing hybrid vigor which may actually be taller than the homozygous tall plants. However i'm not sure whether hybrid vigor sticks around in heterozygous F2 plants or not. According to Breeding and the Mendelian Discovery by A.D. Darbishire, he say's this on page 163:

Yeah, i wasn't aware that there were 5 genes that could be responsible for height. But often i suspect that it's not just a case of a simple recessive dominance kind of deal. In the case of some dwarf x tall crosses i suspect that sometimes it's closer to co-dominant. But your right, actually crunching the numbers should shed some light whatever the case may be. If it's as simple as what i'm suggesting then technically you should get about 1/4 tall, 1/4 dwarf, and 2/4 intermediate. But if the numbers are different, then perhaps your right and there are other genes at play.

Inspiring work, templeton! How can you recognize the dwarf trait so early in the seedling stage? Rebsie's video shows how apparent the difference between tall and dwarf internodes are even in the seedling stage. It even seems possible to identify heterozygous offspring which are half dwarf and half tall as there seems to also be a height difference between them and the tall ones. www.dailymotion.com/video/xcwxai_introduction-to-luna-trick-pea_tech..If mendel was the father of genetics and pea breeding, then surely rebsie is the mother of pea breeding as i think she has inspired a whole new generation of pea breeders. Interesting that she said she was inspired by carol deppe.

I'm just following both projects as a curiosity. I had heard long ago mutation breeding was a thing, but i guess i had just assumed they didnt do it anymore or that there wasn't much merit in it. It seems that i may have judged and assumed too quickly. I will be watching both projects with interest and may attempt building one or both machines in the future. I might eventually use it on ornamental corn, but i think my first interest would be something like peas since i'm already working with those more at the moment. I would be curious to see what kind of diversity it could produce on TPS or TSPS though, even tomatoes (or even squash).

Anyone try Calvin Lamborn's latest parsley-pea types? Apparently he calls them "snap-greens". A catchy name i suppose. It looks like you can order his peas from his website, but i get the feeling those are large quantities for large growers. Any of you large growers willing to get some and send me a few seeds next year? I know raymondo has imported seeds to Australia. Since this is a commercial seller of seeds i would think it would pass through customs easier. And we know that it is easier to send seed to the U.S. from Australia than the other way around (although apparently some do make it through). Also i'd be interested in getting some seeds for the purple pod parsley i suppose since it has been given good reviews. The only one i have now is some saved seed of a sugar magnolia that had these (but that is a tall pea and ideally this trait is only suited for dwarf or extra dwarf peas. Is this a variety still sold by peace seeds? www.eatmorepeas.com/product/MSP-220.htmlwww.eatmorepeas.com/product/MSP-151M.htmlwww.facebook.com/eatmorepeas/

So i woke up to a hot room (its still 2am) and felt like i was being roasted alive. A combination of warmer than i like inside heat setting, slightly dehydrated state, and a fan just circulating hot air ( and felt like it was warming the air too with a hot motor). Anyway, long story short, i turned the fan off and opened the window. The cool air is great. But the night is mostly a clear night. The first thing i noticed was a nice constellation near the moon. It looks like maybe orion. But it has a bright amber colored star or planet. I've never seen an amber colored star before, so that was cool. The second thing i noticed are the frog sounds down near the creeks and ponds. Rather relaxing nighttime sounds. Then i noticed there is frost down on my garden fields, but not everywhere. Seems to be selective the more open areas like where my crops are planted. I guess this is nighttime radiant cooling at work. I've heard joseph mention radiant cooling at night before. I do live at high elevation (5000ft), so that should mean the atmosphere is thinner here and more solar radiation can come during the day but also that more heat can be lost at night compared to lower elevation areas. Google says temp is 50F, but obviously the frost areas have to be at least 32F. Interesting heat difference. (good thing i have frost tolerant watermelon seedlings). This pdf seems to really shed some light on the interesting radiant cooling phenomenon. www.asterism.org/tutorials/tut37%2520Radiative%2520Cooling.pdfedit: it's now about 3:30am and there is now a herd of 5 deer now munching away in the yard. Seem to bee favoring the leaves of the apple trees and the grass under them. But if they find my beans they will probably eat them.

Not much to really report on myself, but i'll give a brief overview.
Pea plants are growing at a fast rate. The Mighty Midget peas in the cold frame are much taller than usual for me, but they are planted in some good soil, so either they just have more nutrients than usual (which i think they do) or these are a forgotten attempted cross in which case these will not be extra dwarf peas and i can recover recessive offspring next generation. Of the remaining peas one of the most interesting lines is one of my labled attempted cross. I planted seeds from what looked like a yellow pod. The cross label say's Attempted Opal Creek x Joseph's Red Pod. If that's true then opal creek was a yellow podded snap mother and pollen was from one of joseph's red pod f4 line. The seedlings from these are showing considerable red anthocyanin in the leaf axils and tendrils even at seedling stage. Since Opal Creek is a white flowered non-anthocyanin mother these are excitingly encouraging signs. If it was successful it should be a good red pod even in the F1 (fingers crossed). There are a few seedlings in other plantings (one in Biskopens) that are also showing higher red anthocyanin in the foliage compared to their siblings next to them. Hopefully this is a sign of other successful crosses (such as Biskopens x Sugar Magnolia). If i find any purple pods in my Biskopens patch i will know.
Still a few watermelon seedlings growing. 1 sunflower seedling that i did not plant growing. Beans are growing great. Various tomato seedlings started inside. The Cheesmanie and galapagense seedlings are giving me the most trouble as they are so small and seem to grow rather slow. The Sara's galapagos natural hybrid in comparison is a fast grower. I drove down to Boulder, CO specifically for a few plants of an 'Anasazi' tomato. Reportedly from Anasazi dwellings, but that is hard to confirm. Even if not, it won tied with Pineapple for best tasting and is a saladette size tomato and apparently grows well in Boulder, so should grow well for me. Several sweet potato slips rooted inside. That's about it for now.

Are the risks only when the bulb is on, or are their any hazards when opening the door ? If it is only when running it is easy to program the oven to run in a few minutes and then leave the room Yes, i'm mildly curious to know if you were able to tap into the existing electronics. Based on your testing it looked like you were. Im assuming you just ripped out the microwave generator cube thingy and wired up a standard 120vac uv light bulb. In which case the microwave timer and safety button cutoff (when the door is open) should still work.

interesting. But shouldn't you put more orange plexiglass infront or behind the exhaust vent for safety?

People have become so estranged from actual Nature; every year more are living in apartments with nowhere to garden ...What's a tomato? ...you mean "pizza sauce" doesn't just appear in the store? actually, speaking of tomato sauce.. i have since stopped ordering pizza with plain 'ol tomato sauce. I now order mine with New Mexico style hatchback green chili sauce... mmmm... It's amazing! People always rave about Colorado / New Mexico green chili. I never dreamed that it could be used in place of tomato sauce on a pizza.. I ended up trying it a few months ago when i learned other sauces were available from a local pizza place, but that they don't sell pesto sauce since no one ever bought it when they did carry it. While i do now enjoy pesto pizzas, i prefer green chili sauce pizzas over any other now.
