Red podded pea - some success

[templeton]

My F2 growouts of yellow pod X purple pod peas has revealed at least some success - a red blushed yellow pod. A charming looking thing.
Have to wait a while to see if it has any snow pea genes in it. This is realistically only a good candidate for further crosses - the parents are a fibre podded purple, and a not very nice yellow snow with few redeeming features apart from its pod colour.
for those interested but who don't know, yellow pod is recessive, purple pod is 3 dominants and red pods are purple over yellow. So this is homozygous for yellow pod, homozygous for A the anthocyanin switch (both parents carried A because they were both purple flowered), but it looks like it is only carrying one of the genes for anthocyanin expression in the pod (giving rise to the red dusting) - which may or may not be homozygous.

I might grow it out over summer in the shade to see if I can pull out some homozygous anthocyanin expressing progeny.
I haven't done the stats, but it looks like there are a surprising number of fully purple and fully green plants in this F2 generation.
The greens must have A, since both parents did. But that means they are not even heterozygous for either of the purple genes, nor homozygous for yellow.
I must do the stats when I get a moment. Pity I rogued some of the plants last week

Well done.

Looking forward to what appears in future generations.

I got about 14 seeds this fall that were the F2 of a cross between [my earliest shelling pea X Austrian winter peas]. I didn't expect to get any offspring, but I planted some sacrificial seeds in a slightly warmer microclimate and they produced a few seeds.

Very nice T. It's pretty in its own right.

I have a suggestion. Consider using a purple-podded snap pea instead of the fiber-podded. There are varieties out there like "Sugar Magnoila" from Peace Seeds:

Great project. I look forward to seeing how it turns out.

Thanks greenandgood, and welcome to the forum! We look forward to seeing more from you.

I know for myself from all three varieties of purple podded peas i grew this past year that Sugar Magnolia was the only non-fiberous purple podded pea to do well with the dry heat we recieved this march. All the others failed miserably. Perhaps a fiberous purple podded would have done fine, but starting with a purple snap should speed things along a lot faster.

I know some people in Australia were concerned that an order of Sugar Magnolia would not get through the seed Nazi's in customs, but i think they would make it just fine (at least if someone filled out an international customs form).

Thanks G&G.
As keen pointed out, Sugar magnolia isn't available here - but me, and I think Raymondo, are working on developing some good coloured snaps and snows. The red is a bit of a side project, really - pretty easy to get in the F2 - but getting one worth eating and growing might be slightly harder. Over the last few weeks I've got a number of full and half purple snows that are going to be worth exploring next season, and some interesting crosses to dwarf, semi-leafless, and disease resistant parent lines that could add some interesting variety.

Using Sugar Mag might take the fun out of it. I'm beginning to be aware that the end point is really only there so I have an excuse to play with the process.
I'm on holidays at the moment, and will have plenty of time to update my blog on current progress on coloured peas, carrots and parsnips, with pics and stuff - I've been very lax over the last few months

It would be good to develop other purple and yellow snaps independently of Alan Kapuler's work in any case, so a diversity of genetics becomes available in those colors.
