Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

It's like the parentage detective of the aughts.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

Don't worry about it.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

Okay, back to apples.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

Let's talk about Apple Willie Wonka land.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

Susan Brown and her team at Cornell Agrotech are inventing brand new varieties of apples all themselves.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

How are they doing that?

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

So in order for Susan to create this brand new apple, this cross between these two different apple trees, she has to be able to choose the parents.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

And that means she has to beat the bees.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

You probably know what the petals look like already, but the anthers are the little almost antenna-looking things in the middle of the flower.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

They're tipped by pollen.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

So she takes those off.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

That's intense.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

Susan's emasculating these trees so the tree is not, like, appealing to the bee.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

Yes.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

So that apple tree is what they call the seed parent.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

And then they pick the other apple they're going to cross it with, which is called the pollen parent.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

So they collect that pollen in little plastic vials about the size of like a film canister.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

Susan actually showed me some.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

It basically looked like maybe a teaspoon, maybe two of this really, really fine yellow powder.

Short Wave
An Apple Is An Ovary: The Science of Apple Breeding

Wow.
