God Clone Planner
Use this Rust god clone calculator to add the seeds you have, set how many G's and Y's you want, and find the best planter layout to breed that clone.

GGGYYY = GYGYGY = YYGGYG — all the same god clone
What is a Rust God Clone?
A god clone is a Rust plant with the perfect GGGYYY genome — three growth genes (G) and three yield genes (Y), with no W (water hog), X (empty) or H (hardy) bringing it down. This Rust clone calculator helps turn your starting seeds into that target genome. A god clone grows the fastest, produces the most cloth, berries or scrap per harvest, and reproduces clones with identical genetics.
How the planner finds your route
The God Clone Planner takes the seeds you already have, scores their genes, and works out the shortest crossbreeding path to GGGYYY. It checks every combination of 8 parent plants surrounding 1 centre seed, calculates each gene's vote weight, and ranks the routes by their probability of producing all-G or all-Y at every locus. If a single round can't reach GGGYYY, the planner automatically searches Gen 2 — the offspring of the first round become parents for a second.
How to use it
- Add your seeds. Type or paste each 6-letter genome (e.g.
GYWXGY). The planner accepts up to 16 starting seeds. - Run the planner. It outputs a 3×3 layout showing exactly which seed goes in each slot.
- Plant and clone. Place parents in the 8 outer slots and your candidate centre seed. Once the centre crosses, clone it before harvest to lock in the new genetics.
- Repeat for Gen 2 if needed. If you didn't hit GGGYYY in one round, plant the new clones and run another crossbreed.
Tips for breeding faster
Run the Seed Grader first to filter out useless D-grade seeds before you start, then check plant timing with the Rust plant growth calculator. The planner works best with at least 6 strong parents (S, A or B grade). If you want to understand why certain layouts work, the Crossbreeding Simulator walks through every gene vote in real time.
Why GGGYYY beats every other genome
In Rust, G genes give roughly +30% growth speed each (capped at 90% with three) and Y genes give roughly +15% yield each (capped at 45% with three). A GGGYYY plant grows ~2× faster and produces ~1.45× as much per harvest as a plain seed — that compounds across hundreds of cycles. There is no genome that beats GGGYYY for hemp, blueberries, pumpkin or corn.
