Everyone's Pea Projects?

[Alex]

The Kelvedon Wonder pea is generally considered a heat-tolerant variety, though it performs best in cooler conditions and requires regular watering during hot, dry spells. It thrives in temperatures between 45-80°F (7-27°C), tolerates downy mildew, and is resistant to pea wilt, but its heat resistance varies by individual experience and environmental factors.

Oregon Sugar Pod peas are not heat tolerant; they are a cool-weather crop that thrives in mild temperatures and does not set pods well above 80°F (27°C). While they can be grown as a spring or fall crop to avoid extreme heat, they require planting early enough in the spring to mature before hot weather arrives, or late enough in the summer to mature in the cooler fall months.

My temperatures: daily high temperatures are around 87°F (30,5°C), rarely falling below 84°F (28,9°C) or exceeding 89°F (31,6°C).

Opal Creek pea was tested in Hawai and may be one of the most heat tolerant peas.

I don't know of any garden pea that will tolerate dry conditions:  the usual advice to get them through heat waves is to keep them well watered.  Maybe a wild pea for the drought. 
Golden Sweet and Tai Chung were both flowering here for a couple of weeks of highs 80+ this summer but were kept watered every day.  Tai Chung flowered normally (except the pink petal faded to white after a day) and set slowly (or maybe normally) but Golden Sweet barely seemed to open its flowers, however it was really fast at pushing out the pods. The flowers seemed to wilt without opening but did not stop production of pods, that's for sure. 
I noticed the same thing on the second trellis with Calvert and Japanese Climbing Snow, that flowers were small and weren't fully opening, and pods seemed to appear out of nowhere.  Not sure which pea was which. The other snow I have is a crossed line out of Amplissimo.  They were a little later but are still flowering and pretty sure they started during the heat too.

Just posting to say I could not confirm xenia effects on the seed from the reddish pod, because there's a wide range of colors and including speckling on some other seeds in this generation. So no way to tell if the speckles are from a cross or not.
Only 3 peas but I will see what turns up when I grow them out.
I did find a second reddish pod on an un-numbered later plant, which I also tucked away to dry.
Shown below the range of colors in these F3 seeds.
The reddish pod pea is speckled like Golden Sweet on the left, but #13 pea is even more like them.
I'm actually surprised to see so many different colors from the F2, not sure what genes are associated or how they all ended up in one cross.  Maybe Sugar Sprint has some color genetics that are suppressed in association the white flower gene.

Do you mean Pisum sativum subsp. elatius, Pisum fulvum? I couldn't find any seeds. Does anyone have any?

I'll have to check my stash. But I might still have some pure Pisum elatius seeds from Israel. I know I sent most of them to someone in Washington or Oregon this spring, so perhaps they have grown those out?

I got some P. elatius from you this spring, and only used 8 seeds out of the lot. I was testing to see how well they fare in my climate, south central Alaska, and they didn't fare that well. Same story for the P. fulvum seeds I got from GRIN, but both species did flower despite being seemingly miserable in comparison to my snow peas. I can send them back if you ever need them, just message me about it.

[Alex]

AndrewB, Tarruvi, is it ok for you to send P. elatius, P. fulvum to me?

Since my last update on my new batch of F1s grown on the windowsill for my second attempt at red podded peas, they've survived and are now developing seeds. One more good sign, is that none of the pods exhibit splotchy coloration. The very thing that ruined my previous attempt, making all the F2s in that batch have zero solid colored pods. So this new batch of developing F2s are looking promising. And once the seeds are dried, all I have to do to make sure they're hybrids is look out for any speckles on the seeds (a trait of the yellow podded parent, this would confirm I had successfully made a cross and can work with these seeds next year).

As for the other hybrids, they also made it through alright. The Parsley Pea x Salmon Flowered F1s have started making seeds alongside the purple x yellow hybrids. The pods seem to go in pairs, and may have developed 3 pods per node if they were grown outdoors (Why I think this, is I had some Yellow Seeded x Iona Pea F1 hybrids grown outside this year, and they produced tall plants with 3 flowers per node.) I'll just have to wait until next year to confirm this though...

Now, as for the P. sativum x P. fulvum F1s. They're doing great, but with one struggling to catch up to the other 2. I have pictured the largest of the bunch, and the second largest flowering. These two have about the same vigor that their snow pea parent would have grown indoors, which I'm grateful for. If they stay on this course, I'll hopefully have some orange flowered F2 seeds to work with next year. What I'm also interested in, is if the F2 seeds will vary in size? In theory they should have varying sizes, with smaller seeds taking up 3/4ths of the lot.

An edit to the post to show the F1 flower of P. sativum x P. fulvum in full bloom. It's quite stunning, a nice bright pink.

AndrewB, Tarruvi, is it ok for you to send P. elatius, P. fulvum to me?

I found the packet of pure Pisum elatius seeds from Israel. It's only about 5 seeds though. I'll try to send you a P.M.

Syrian Pea from "Truelove Seeds" is growing well in sun/partial shade, 30% of population. It reached human height now and is starting to produce pods. One third died from wind shaking, and another third from premature aging.

Just saw an interesting article about new, edible winter peas.

It doesn't sound as though we'd want to eat them as a vegetable, though.

After about 2 and a half years, I finally got a Red-Podded pea:

This is the only plant in the windowsill to have a red pod, the others have some variation of solid green, solid purple, and incomplete coverage of purple pigment over green pods.
This plant is from the fresh crosses I made last year, after the first line of plants failed miserably to exhibit solid red pods and instead had light freckles of red.

I grew this fresh line of F2 plants out in an attempt to get more seeds before spring arrives, I had only about 15 seeds that included this Red-Podded plant. Come spring, I am hoping to have just enough to grow a significant number of F3s. And, since this Red-Podded plant has some pretty purple podded siblings. My hope is that they too will turn out some hidden reds in their F3 offspring. Having a red pod appear after last year's big disappointment was a huge relief. Haven't tasted them, but if the next generation comes in full force. I'll see how they taste.

Also, this seedless pod from the Parsley-Salmon Flowered(Edit: Parsley x Yellow Podded) F2s was pretty amusing:


Edit: The F3s from these plants are growing, one thing I'd like to correct is that the last cross shown was actually some Parsley x Yellow Podded F2s... Goofed up on that one, but the yellow plant stalks coupled with the tendril-less genes look absolutely pretty.

This is one winter pea plant, fasciated and very dwarf, F-2, that showed up in a cross between a normal height fasciated winter pea, and a dwarf winter pea (but ~24" tall, not 12"). There are wild collected peas from Lake Van, Turkey, and from Iran (from GRIN) in the crosses that led to both parents, and occasionally I have seen very dwarf plants pop up, smaller than any plants in the background. Sometimes the very dwarf plants have had poor seed set, but this one looks vigorous and healthy so far.

We had a low of -10F with 3" snow cover this winter, and crazy temperature swings between 75F and 20F earlier in the spring with no snow cover (frost heaving), and they came through fine.
