Do volunteer peas breed true?

Snow peas are one of the few vegetables that do well in my garden, so well that I no longer have to buy seeds. They simply sprout on their own and are reasonably productive for a couple of months in the spring, apparently from pods overlooked or discarded.
Some of the pods are nearly stringless, others have pronounced strings even when the pods are quite small (~2" long). It's been suggested that they have "reverted" from a hybrid to a mongrel variety. I thought this impossible, as pea flowers are said to be perfect and self-pollinating. Is this correct?

If they are hybrids, even the seeds from self-pollinating plants might produce plants that vary from their parents.

no bob, like you've found out, there are bugs which will pollinate beans and peas so they will cross breed.
it's fun to see what happens. :)

Ok, so be it....
For the time being I'll just let them grow and pull out the strings. Otherwise the peas are quite good, with no mildew problems yet.
It does sound like I should expect the volunteers to slowly revert to a more wild state. At some point it'll be time to buy new seeds, but not yet.
Thanks to all for replying!

i apply some selective pressure on the cross- breeds here. some traits i like to encourage such as having purple flowers or shelling easy is another (but not too easy -- shatter is a PITA for dry bean harvest if you don't get them early enough).
for pea pods i try to keep the blocks planted apart from each other, that helps, i'm not sure the peas are actually hybrids. i can usually pick the seeds from one or the other even if they get mixed together.

yes, for hybrids that's the kind of lock in to a seed company that i don't like. it also irks me about the GMO stuff too since i do like to grow edamame soy beans and the fields around us are planted with GMO soy every second or third year. every once in a while i should resource my edamame seeds.

y.w. :)
