The apple is not in the pip

Keeping an apple variety and making a new apple tree are two different projects.

An apple seed looks like the obvious place to put the next apple. Small, portable, already packed. If you liked the fruit, surely this is the part to save.

For an apple of the same named variety, it is the wrong kind of luggage.

Iowa State University's answer to a gardener with an old, declining apple tree begins with the obstacle: apples do not come true from seed. To preserve that tree's variety, its advice is to graft a piece of twig from it onto a rootstock. The future crop travels in a bud, not in the pips.

I find the unnamed tree in that question particularly compelling. The gardener doesn't know its variety. That gap need not prevent propagation. A label would help describe the tree, but a living piece can carry what the label cannot: the material from which more of its fruiting branches can grow.

The resulting tree is not simply the old tree made young. It has a join. Above it is the scion, the desired fruiting variety; below it is the rootstock, including the roots. The University of Minnesota's growing guide describes these as genetically different components. The rootstock strongly affects the tree's eventual size and how soon it bears fruit. Choosing the apple and choosing the scale of the tree are therefore not quite the same decision.

This complicates my picture of an orchard in a pleasingly physical way. I can no longer draw every tree as one continuous family line from a pip underground to an apple overhead. A grafted tree includes a deliberate junction. The variety name on its label tells only part of that story.

Seeds have a different job in apple breeding. Minnesota's account of its programme describes planned crosses, hand-pollinated flowers and the hybrid seeds collected from their fruit. Seedlings are screened, grown and assessed; promising selections are then cloned by grafting or budding for further trials. Variation is sought first. Repetition becomes useful once there is something worth testing repeatedly.

The sequence matters. If every new apple had to be a faithful copy, breeding would have nowhere to begin. If every planting had to begin again with a new seedling, keeping a chosen variety would be a different and much less predictable undertaking.

I like that the orchard needs both procedures without confusing them. There is a place for a new combination and a place for another branch of something already found.

Two small things could leave that old garden: a pip from the fruit and a twig from the tree. Both could become part of an apple tree's future. Only one is being sent to bring the old variety along.
