@t, i think you are right that some of your yellows are less yellow and more green in color. I'll be honest in saying that to me that first one you showed looks like a purple instead of a red to me despite it perhaps having a yellow-green pod underneath. But some of your others really have some nice yellow and red traits to work with. Here are some early ones of mine this season. Most of them are yellows so far. and here is a teaser green. This is from my coldframe haphazard experiment this year. I had sprayed some giberellic acid on a extra dwarf pea and it grew to to an average semi-dwarf height. So i wondered what would happen if i sprayed some on a developing pea pod. THIS is the result! The other green pods are maybe half that size (even on the same plant).

While all the pods are small i can see an abundance of yellow pods forming. Hard to tell at this stage which ones will develop red and which ones will not. Have at least two showing slight reddening of the pod edge. Have one in the yellow line that had green pods and now is turning purple (that most likely indicates a successful cross last year). Should be a good year for yellows and reds.

steve1, nice red you have there. The yellows are currently all in bloom, and at least 1 red-podded is in bloom, along with the large-podded ones bred by the Kapulers from Oregon that i'm trialing. The Kapulers version of a large podded is doing so well plant wise this year that i think i will eliminate Carouby de Maussane and Bijou from my garden. I expect to see some yellow podded peas a day or two before any red ones, but the reds wont be far behind. I attempted three crosses between the february planted coldframe peas between Mighty Midget and Purple Passion (a pure breeding purple seeded pea). Only one pod seems to have taken. My plan this year was to plant my peas in a large circle to help protect the teosinte/corn hybrids in the middle from racoons later in the season. But the shade has attracted a rabbit to dig a hole next to some of the peas. I'm watching the rabbit carefully, but so far it hasn't done too much damage so i'm willing to let it slide if it remains that way. EDIT: There were four seeds from an attempted cross i think between Opal Creek (yellow-snap) and Joseph's Red-podded from last year. Out of the four at least two are white flowered (probably indicating they selfed), but at least one has colored flowers and is clearly showing yellow stems. We will see what happens with that one. In other unrelated news i just finished weeding one patch of watermelon. Boy do those weeds grow fast. Some of the weeds are actually feral herbs like thyme and catnip. I think from the cold tolerance after germination only about 4 survived give or take. But many of the others have germinated on their own once it warmed up. I think enough have survived to make a decent crop, provided i keep them weeded. One is actually a large melon. Perhaps Josephs cantaloupe/musk melon since it's growing very fast.

My first flower on any of my normal planted peas was spotted today. It looked to be a rather short node. It was on Mighty Midget my extra dwarf pea that is consistently the earliest to bloom for me (other than Tom Thumb which i did not plant this year). Today i attempted a few crosses between The tall gibberellin treated Mighty Midget in the cold frame with the Purple Passion also planted in the cold frame (planted in february?). I even labeled them with fancy jewelers tags this time All the other peas are starting to get rather tall. Except for Canoe which is a dwarf, Dwarf Grey Sugar, and Orange-Pod which appears to be even shorter than Mighty Midget(!). So much so they are partially shading the Teosinte and corn hybrids within the circle. Watermelon seedlings are starting to come up (if they hadn't germinated already). Some melons mixed in there too, somewhat hard to tell the difference. I'm having a hard time weeding in some areas. But i think i will get enough even if these were all the ones that germinated and grew. I'm having a hard time with some of my tomato seedlings. Many of them died when i may have put them outside a few weeks too early. However some have survived and i will pot them up later, and i planted a few large ones yesterday. I will do my best to see if i have any seeds for the others that i can replant now. I planted three 'Anasasi' tomatoes next to each other for my conductive helical coil experiment that is finally built. One will have a full strength coil, another will have one with slightly fewer turns, and the third will have none and will be the control.

I'm pretty sure that you could get that concrete thickness down by a lot by building the thing underground and adding atomized metal or something like that to the part that sticks up above the dirt. we have very heavy clay soil wear I am, and soaking it with water (the clay soil) would make it pretty good containment I think. and of course, it would need to be tested with a Geiger counter to make sure it worked. not a bad sounding idea. From what i've read many of the designs actually have a hole in one side (like the top or the back) rather than completely contained so that the x-rays escape in a safe direction rather than dangerously bouncing around. I'm not sure what would be better though. I would think if you left it alone for awhile the x-rays would naturally dissipate even if bouncing around in a completely closed system, but i don't know.

It's certainly been cooler and rainier than usual.

I wonder how much gene mutation is actually just changes to epigenetic activation/deactivation of genes. There are chemicals that are known to remove/reset the methyl group proteins that bind and deactivate expression of DNA. Makes me wonder what x-rays would do to those. www.youtube.com/watch?v=kp1bZEUgqVI

Jumping off the post i put in the x-ray thread i'd like to start collecting variegated corn to breed with again. I'd like to recollect some of the "old gold" gene for yellow variegated corn, but i'd also like to get some others including white variegated corn. I'd be especially interested in white/green varigated corn seedlings like shown in some of the pictures in the Maize Genetic Coop Center photos. maizecoop.cropsci.uiuc.edu/mgc-info.phpI probably can even request some seed from the Maize Genetic Coop Center (i think i did once a long time ago), but i'm not sure which accessions to request as everytime i try to browse through i get overwhelmed with too much to dig through. Any one know how to do it? Maybe i should just email them and ask for help. I tried growing Japonica Striped corn twice, but i think i got poor seed stalk as i've never seen one as variegated as in the photos they show. The best i could get was one or two measly tiny stripes and they weren't really all that noticeable. Perhaps i just got bad selections of it. There was an old variety that may be extinct and/or long out of cultivation i had found reference to one. I think it had the name "tiger" or something like that and was a heavily variegated white/green variety that was also a dwarf corn as well. I'll try my best to find the reference if anyone can help me track it down.

That corn paper you linked to was interesting. i only briefly skimmed over it. It was interesting that they hadn't encountered any dominant gene mutations, but that some of the recessive mutations will sometimes convert themselves to dominant traits. Weird concept. I'll have to try reading it again later. I believe the "old gold" gene in corn that Joseph Lofthouse has posted pictures of in the past were produced using radiation. And i believe they are also a dominant trait. I originally sent him the seed that i originally got from Ken at the Long Island Seed Project. Sadly i don't have any seed for that trait any more, but i'd like to get some back to breed with again at some point. in fact i'd like to start working with variegated corn again. I really really like seedlings that are variegated white and green. maizecoop.cropsci.uiuc.edu/mgc-info.php

the tutorials on united nuclear are pretty good too. that is where i plan to buy the x-ray tube and socket from. I've bought chemistry supplies/equipment from them before. They are one of my favorite shops. Although sometimes their prices are higher than others. But for radioactive supplies i would think they would be a good place to use and fairly singular/unique in the stuff they have. And since they do this kind of stuff all the time they should have the knowledge to do it safely. Perhaps send them an email over here. Who knows, maybe they will jump into the discussion.

That link is indeed funky somehow. After fiddling with it i got it to work for me. Try copying and pasting this in manually: www.topbulb.com/gpx9-bulb-9w-t4-germicidal-lamp-uv-c-g23-2-pin-base-clear-glassthe one he linked to is obviously not an LED. And is some sort of two prong bulb. you had mentioned x-ray bulbs are easy to obtain. After briefly googling for some the best i could find are called "collimator" bulbs meant for dentists. I guess Collimator means a highly focused or directed beam. I would think a non-collimated x-ray bulb would be best, but perhaps any would do in a specially designed x-ray seed chamber. Perhaps line the inside with metal to reflect the x-rays all around the inside? No idea what kind of x-ray bulbs are used for bone x-rays.

Ate one of my Hopi White squash from last year this week. I made a Hopi Squash Yellow Curry Soup that i threw together. It turned out pretty good all things considered. Inside i found these darker seeds segregating out from the rest. Is this a normal seed coloring for Cucurbita maxima? Does this indicate that these seeds are crossed since i've only observed white seeds from this line before? Is this a recessive gene segregating out? Anyone want to try and grow these? gilbert , do you want to try these?
