P. fulvum.
First time growing this species.
Dainty little flowers and pods.

Some of Andrew’s crosses of DGS.
F2+ (?)

Starting accessions from JIC.
One unsoaked seed, and two soaked.

Most have sprouted now, and will be going in potting soil later today.

Yes.

Unable to access to greenhouse space due to closures.
I’ll be killing a larger number of seedlings than usual, due to space and north facing windows.
No bales of Promix when I went shopping, so Miraclegro it is. :(

That's a nice spreadsheet!

When it comes to purple podded varieties i have my suspicions about why some lines wash out or are more variable than others. You need the dominant gene "A" in combination with at least one copy of each co-dominant genes "Pur" and "Pu". But i suspect that you get better pods if you get homozygous alleles for both of the co-dominant genes. My red-podded line is pretty stable for purple genes as it stand right now, pretty much no variation other than spitting out yellows occasionally. I don't think you need the "A" gene in homozygous form, but if you don't want yellows or green pods spitting back out, then you yes you do.

Anthocyanins are also temperature and environmentally affected, so it may not work as well in certain climates. Perhaps anthocyanin plants get purple well in my area because i am both at high altitude with a thinner atmosphere (so more intense sunlight), but also we have a semi-arid climate, so few clouds. But not as hot as say Texas.

All these factors combine may explain why it is so hard getting good tasting purple podded varieties, let alone red podded ones.

p.s. do you happen to have those "o<y" golden yellowish pods in your collection or just reading about them? I've noticed some people seem to have some yellow podded breeding lines that seem a darker yellow that does not fade as much, and i'm curious to know what is going on.

I will be growing out another generation of [orange-pod x gp] in hopes of a deeper yellow combination, but as of now i have not seen anything interesting. "gp" fades as the season goes, while orange-pod increases as the season goes. Theoretically it could be a nice combination.

p.s.s. ;) i'm not sure where you would put it in your spreadsheet, but when the "b" modifier gene is combined with a purple pod you get a sort of maroon red, and i suspect if combined in a red pod with gp underneath you would get a "peachy pod" which would look really cool like rebsie's original "peachy pod".

I don’t have “o<y”. (Yet. 😁)
If JIC has a line with it specifically I haven’t found it, but that is likely my lack of search skills.
Next time I request accessions I’m going to ask for some “o” and “gp” so that I can compare.

Orange pod...doesn’t the pigment show up in the fibre of the pod?
If the pod has fibre, it won’t be a great snap/snow type. Right?

I didn’t include the chart with the reds.
Still trying to get the various gene combinations involved straight in my head.
Interesting observation on “peachy” pods...

I’ve been reading a fair bit on the JIC website, and the following is what I have been able to decipher so far.

Accessions I have received from JIC and will be growing (among others):
JI0014 Caerulicans - ar
JI0795 WBH 1307
JI1860 Cerise - ce,CR
JI2776 Appelblossom - cr
JI0093  P. sativum - Afghanistan (brick red flowers)

I’m pretty sure my pink flowered rogue in 2019 has “b” and either “am” or “ar”
I’m planning to cross it to figure out which it is.

So some studying flower colours for me...

I think I’ll start a new thread for this. 🙂

Interesting.  So a little more selection required for Heather.

Mind you the purple genes are very fickle and can change to semi purple and even green easily.  We constantly need to select for the best purples when seed saving. 

Attached is a selection of Sugar Magnolia pods that illustrates this.  For some reason edible podded peas suffer from this purple deterioration much more than purple podded shelling peas.

Are the purples fickle, or is it because there are different alleles in a population?
Been trying to get this figured out...

I have some of this variety growing, and will post pictures of flowers /pods if the darn sparrows will leave them alone long enough to flower.  Thought I had them covered but they are striped to stalks again today.

Interesting that sparrows are a problem for you.
Thankfully that hasn’t been a problem for me. That said...

I’ve had my upper part of my plantings mowed by groundhogs twice now.

I place the top half of an old bunny/ rat cage over the planting, to protect the young plants.
Normally I open the top, and use it as additional trellis, but didn’t get to it in time this year.
Old bird cages can be useful in the garden, and they have convenient access doors. :)

Lovely big pods! Any comments on it's culinary qualities?

I don’t normally taste test from the Seed Library garden, but you provided me with an excellent opportunity for a taste evaluation. :D

I sampled two very young pods (flat pod stage, 2” max.), and two with maturing seeds.
I couldn’t locate any at what I consider the best point of maturity: seeds half to three-quarters mature.

Flat pod: tender, good flavour for pod at this stage.
Mature: crisp juicy pods that are sweet! Not stringy. (Yum!)
Over mature pod: pods are still sweet, which compensates for the peas being on the starchy side. The peas at this stage are better tasting to me than a shelling variety that has been on the vine too long. (Still yum!)

I gave some seed of this variety to another gardener in the community garden.
She likes it, and has been asking me questions about how to save seed.

(I’ve loaned her my copy of “Seed to Seed”. If that gets an enthusiastic response, the next book will be “How to Breed Your Own Vegetable Varieties”)

Grumble, grumble...had to turn on Javascipt.
(But still no info on this variety)

Eye-candy offset for grumbling:

Some griping and whining deleted. :)

Thanks.

I *really* hate playing “Whack-a-Mole” on websites.
The three ‘click’ rule applies, and the search feature is not much help.

Unfortunately, the link you give above goes here:

Perhaps start some in pots at the same time that you start your eggplants/tomatoes?

If they are daylength sensitive, you might get the plants mature enough that they flower in the spring/early summer and are able to mature some seeds.

(Just tossing out ideas)
