2026 GTS Grow Reports: Peas (Pisum sativum)

How did your hand crosses from last year turn out, @MichaelFomhar?

I ended up planting out four of my crosses in October and three of them managed to overwinter and are producing F2 seed now. Here’s a cross between Sugar Magnolia snap pea and one of my snow peas. It has some of the purple pod color but with the snow pea pod shape. My other crosses are also showing intermediate traits so I’m confident they were effective. I’ll be planting these F2 seeds ASAP to get an additional generation in this year.

This spring I planted out more seeds from each of these crosses along with four additional hand crosses I didn’t have enough seeds of to risk overwintering, and all of the parent varieties to make additional crosses this year. The variation in growth habit between varieties and crosses is already visible.

I plan to mostly let these F1 crosses self this year in order to collect the more diverse F2 seed, but will be doing some back-crossing to target specific traits from parent varieties. I’ll mostly focus on making new crosses between varieties I missed last year, with a focus on crossing exceptional traits (colors, flavor, productivity, etc) with highly disease resistant varieties from the OSU breeding lines (Oregon Sugar Pod II, Oregon Giant, Cascadia Snap, etc.). Most of these F1 crosses will be snow type pod shapes because that trait is dominant, but I hope to select out snap and shelling pod types again in future years.

I also hope to collect enough F2 & F3 seed to return to the GTS seed mixes so other folks can select from these crosses. If anyone is interested in how to do this yourself, I put together a visual guide last year.

Only one out of the several I did took, and was eaten by a pekish toddler a couple weeks later :joy:
but I’ll be trying again shortly, they’re only about knee high or so now. And her impulse control has improved so the flag tape should help this time​:crossed_fingers:

Fair enough! My 38 year old spouse absentmindedly did the same with a few of mine last year! :melting_face:

My peas have taken over the garlic! I tried to interplant them with favas to use as a trellis but they decided to grow beside them instead, and now cling onto the garlic on the border of the garden bed. A crazy sideways leaning pea garlic jungle! First time growing soup peas and I think i will let them all dry down before harvesting..?

Seems reasonable to me if it’s your first time growing them and you’re just looking to increase seed from the ones that do best for you.

The GTS soup peas are sort of a maximum diversity category that includes peas specifically bred for use as dry peas as well as some sweet shelling peas and edible pod types. It may be worth sampling pods from plants that do well to evaluate if the pods are edible and/or the peas remain sweet rather than going starchy as they mature. If either of those uses are of interest to you, you could flag those plants and save seed separately.

F2 seed from the hand cross of my ‘Swedish Red’ dual use snap/soup pea and ‘Golden Sweet’ yellow podded snow pea.

Only this single pod segregated out with partial red/purple seed coat, but there’s quite a bit of variation showing up in seed size, shape, and (possibly) sweet vs starchiness based on how much they’ve shrunk as they dry down. I crossed these last spring and grew these plants from F1 seed over the winter.
