Growing Heirloom Seeds & Seed Saving : Cross-Pollination in Squash Types

Okay, now we’re ready for something a little
more complicated, the squash. Now, many people are intimidated by the idea of saving squash
seed because they have a reputation of cross-pollinating with with all the squashes in the garden.
But that’s not really accurate. The squash will cross-pollinate within its family group.
So this maxima will not cross-pollinate with this moschata. And this pepo will not cross-pollinate
with this maxima and so on and so forth. And this Argyrus firma will not cross-pollinate
with this maxima. So once you’ve learned your families, this being the best source of information
to learn your squash families, you can begin to plant your squashes in groups. So this
is a pink banana next year. We’re not absolutely positive that this seed is pure because there
are other pollen in our garden that might have cross-pollinated this fruit. However,
this was off in a corner with a bunch of other pink bananas and for our purposes in the backyard
garden, we might reasonably guess that these seeds will be adequately pure or partly pure.
If not, we can always do a little test. We can grow some of these seeds to their first
fruit, check what’s coming. We can tell from the embryonic fruit whether we’re getting
a pink banana or some kind of a “scrumpkin” where the genetic dice got rolled and all
kinds of qualities are coming out. Why don’t you go ahead and open up that squash? This
is a mature fruit. We always choose seed from the biggest, most mature fruit.
