In my experience Wando is not heat tolerant. But that's just my experience in in Colorado. Peas are sometimes mislabeled, so it's possible i never even got true wando, but who knows. I second the advice for trying native seeds varieties for crossing. However to reselect for "snap" type peas you will have to recover several sets of recessive genes responsible for edible pods.

One approach would be to grow a lot of Sugar Snap peas and inspect each individual plant looking for signs of heat resistance. There is some natural variation, and also the possibility of a lucky mutation.

If you find signs of heat resistance, label that plant and save seeds from it for growout the next year, for further selection for heat resistant traits.

Max Farms (and Texas Hydro) I reset up my account with Houzz to mention native seeds .org . I over looked Max mentioning of them.
