Cloning and crossbreeding in Rust: from seed to target clone

Start by choosing your growing goal, then record the genetics you already have. This guide explains the basics for planning with ClonePilot.

Updated
Applies to
Rust PC, with vanilla as the reference. Based on Facepunch documentation, without measurements in the current game build. Modified servers may differ.

Read the six gene positions

A plant has six gene positions. G favours growth, Y yield and H resilience. W increases water demand; X provides no positive effect. Always record the complete gene sequence for your plan.

Explore seeds and preserve useful genetics

Seeds receive random genes when planted. A clone instead inherits its source plant's genetics. Preserve useful plants as clones rather than relying solely on new seeds.

How crossbreeding works

During crossbreeding, nearby plants of the same type in a planter can overwrite genes position by position. Negative genes carry more weight. Inspect the resulting plant. Exact weights and tie rules are not verified here as the current vanilla formula.

Which godclone suits your goal?

Here, a godclone has genetics suited to your goal. The wiki describes GGGYYY and GGYYYY with different growth/yield trade-offs. H can help in harsh temperatures.

Planters, sprinklers and lighting

Supply your planters with lighting and sprinklers. Use fresh water or purify salt water. Check the plants to verify that your layout provides suitable conditions.

Use a breeding plan you can verify

Our suggested workflow is to record each source plant's gene sequence, choose a target and keep useful clones before an experiment. Plan with ClonePilot and compare the actual gene sequence with the expected result after each cross. If they differ, check your inputs, plant type and neighbours first, then account for server modifications.

Common questions

Are W genes useful because they provide more water?

No. W increases the plant's water demand.

Is GGGYYY always the best clone?

No. Growth speed and yield are different goals; the wiki also describes GGYYYY.

Why does a plant with good genes grow poorly?

Check its supplies and environment. A poor condition can limit the overall value.

Should I purify salt water for a farm?

Yes. The wiki's setup routes salt water through a purifier before supplying sprinklers.

What this guide does not establish

  • Exact gene weights, ties, distances and stage timings are not established as current primary-source rules.
  • This guide does not establish guaranteed ClonePilot success rates.
  • No universal sprinklers-per-planter ratio; wiki layouts are historical and were not measured in the current game.

Open means open. These points stand here instead of being replaced by a stronger wording nobody verified.
