Rust Genetics Calculator
Type in your clones. See which ones to plant together, and where, to breed the genes you want.
Your clones
Type the 6 gene letters of each clone and press Enter, paste a list, or read them from your screen. Letters: G growth, Y yield, H hardiness, W water, X empty.
Share your Rust window, then drag a box around the six gene letters. The image stays in your browser.
What do you want to breed?
Genes count in any order: YYYYGG and GYGYYY grow the same.
You can breed
Add at least one clone to see the best breed.
Rust genetics: common questions
- What are the best genes in Rust?
- A god clone has six green genes and no red ones. Common targets are YYYGGG, YYYYGG and GGGGYY: Y raises the yield and G makes the plant grow faster.
- How does crossbreeding work in Rust?
- Each of the 6 gene slots is decided on its own. The game adds up each gene's weight across the neighbouring plants, and a gene only replaces the centre plant's gene if its total is higher. Red genes weigh 1, green genes 0.6.
- How many plants does it take to beat a red gene?
- Two matching green genes. 0.6 + 0.6 = 1.2, which beats one red gene at 1. One green gene alone never does.
- Where do I put the plant I want to improve?
- In the centre of a large planter. It has 8 neighbours, the most of any slot, so it gets the most genes from the plants around it.
- Do different plants crossbreed with each other?
- No. Hemp, berries, corn and the other plants use the same gene system, but a plant only crossbreeds with its own type.
