Plant register: Give the plant a number before the season becomes busy. Keep source lots distinct from positions.

Cross log: Seed parent first, pollen parent second. Record another pollen application in the same attempt’s notes.

Observations: Define the observation before comparing plants. Ten fruits from one plant are not ten independent plants.

Seed inventory: Use the generation that will grow from the packet. Keep any uncertainty in parentage or handling with the lot.

Decisions: Write why you made the choice. Keep some earlier seed in reserve when possible.
