Peas and seed saving

 

I wanted to try "Ne plus ultra" and Alderman this year. Both very old
varieties.
How far apart would I need to grow them to ensure that if I saved the
seed for next year it wouldn't be a 'mix'?
Or is it not possible at all?

Peas (Pisum sativum) routinely self-fertilise, so the expectation would
be that the majority of saved seed would come true. Hpwever I can't tell
you to what degree cross-fertilisation also occurs.

According to Suzanne Ashworth's "Seed to Seed:"

Garden peas have perfect flowers, and are mostly pollinated before the
flowers open.  Having said that, the commercial standard for isolation is
100 meters, and if there is little other pasture for honeybees, they will
visit pea blossoms, increasing the chance of crossing.

Looks like unless you're going commercial, whatever spacing you can manage
would work.  If you're really a purist, which I'm not, you could tent the
part of the row you want seeds from with Remay or whatever the floating row
cover stuff is called across the pond.

I've saved Sugar Snap pea seed from a row adjacent to Oregon Giant snowpeas
with no visible crossing, and that certainly would be evident the next
season.

20 meters is the recognised comercial separatin distance for peas

I hope you have better luck than we had with those varieties, we eventually
gave up planting them as the hot dry summers stopped them growing and they
failed to provide peas in any quantity. We only grow early peas now that are
finished before the heat of summer.
