What are the mutated crop odds after RV Lv. 15?

From RV Lv. 15 you can raise the Plant Research Module to Lv. 4, which gives a 0.405% (about 1 in 247) chance of a mutation each time a field produces a crop. Huge, Colorful and Shining are 0.1% each and Crystalline is 0.005%. Lv. 4 is the max, so raising your RV level further doesn't change the odds.

How often does the Crystalline mutation appear?

It starts at Plant Research Module Lv. 3: 0.00375% at Lv. 3 and 0.005% (1 in 20,000) at Lv. 4.

Can Aniimo or fertilizer raise the mutation chance?

No such effect is confirmed. The mutation chance is set by the Plant Research Module level and the crop type. Placing many fields and harvesting often is the surest way.

Do the odds differ between crops?

Mostly no. Normal farmland crops (Wheat through Pumpkin) all use the same odds. Only the Moondew Crops of the Harvest Moon Festival (Moondew Radish and Waxing Moon Pepper) got higher odds in the 10/16 update: 0.535% without a Module and 0.89% at Lv. 4.

Aniimo Mutated Crop Odds – Huge, Colorful, Shining and Crystalline Chances by Plant Research Module Level

Chance of mutated crops · Plant Research Module Lv. 0–4 · odds from RV Lv. 15 (Module Lv. 4) · odds per type · Module upgrade costs

Fully grown crops in an RV Home field with a rainbow glow rising above them — Mutated crops in an RV Home field

The chance of a mutated crop on your farmland is set only by your Plant Research Module level. Without the module it is 0.05% (1 in 2,000), and at the max Lv. 4 (from RV Lv. 15) it is 0.405% (about 1 in 247). Even at Lv. 4, the rarest Crystalline mutation is only 0.005% (1 in 20,000).

Here are the numbers for how often Huge, Colorful, Shining and Crystalline mutated crops appear on Aniimo RV Home farmland. The tables cover the odds per type at Plant Research Module Lv. 0–4, the chance of a mutation each time you harvest, and the Module's upgrade requirements and costs. The game never shows these percentages.

The mutation chance is set by the Plant Research Module level (RV level doesn't matter). Only the 2 Moondew Crops of the Harvest Moon Festival have a higher chance (10/16 update)
Chance of a mutation: no Module 0.05% → Lv. 1 0.115% → Lv. 2 0.2% → Lv. 3 0.30375% → Lv. 4 0.405%
At Lv. 4 (from RV Lv. 15), Huge, Colorful and Shining are 0.1% each and Crystalline is 0.005%
At most one mutation type appears at a time
Lv. 1 and 2 only unlock new mutation types; the odds per type go up 1.5x at Lv. 3 and 2x at Lv. 4
Moondew Radish and Waxing Moon Pepper: no Module 0.535% → Lv. 4 0.89% (about 1 in 112)

11. Chance of a mutated crop by level

This is the chance of a mutated crop each time a field produces a crop. Wheat, Potato, Sugarcane, Rice, Cotton, Strawberry, Lavender, Soybean, Grapes, Agave, Rose, Cranberry, Ginseng and Pumpkin all use the same odds. The 2 Moondew Crops of the Harvest Moon Festival got their own higher odds in the 10/16 update (see section 5 below).
The Plant Research Module is an RV component you can buy at RV Lv. 6. Even without the Module, Huge mutations still appear at a 0.05% chance.
At Lv. 4 (from RV Lv. 15), which the game describes as "Increased chance of all mutation types", the total chance becomes 0.405%, about 8 times what you get without the Module.

22. Odds table by mutation type

There are 8 mutation types. At low Module levels some types aren't unlocked yet (0% in the table). Colorful appears from Lv. 1, Shining from Lv. 2 and Crystalline from Lv. 3.
The odds of a given type stay the same at Lv. 1 and 2, then become 1.5x at Lv. 3 and 2x at Lv. 4. The total goes up at Lv. 1 and 2 only because new types unlock.
The rarest, Huge Colorful Shining Crystalline, is still only 0.005% at Lv. 4, 1 in 20,000.

33. How are the odds decided?

Each time a field produces a crop, the game rolls only once. So two mutation types never appear together, and you get 1 mutated crop.
What changes the odds is the Plant Research Module level and each crop's own base chance. Right now the only crops with a different base chance are the 2 Moondew Crops of the Harvest Moon Festival. For each type, the game adds "the crop's base chance + the extra chance from the Module level". We have not confirmed any way for RV level, placed Aniimo, fertilizer or items to change the mutation chance. Actual results may differ.
A mutated crop seems to come in addition to the usual harvest, so a mutation doesn't cost you the normal crop.
If you turn on auto-collect for mutated plants, "When opened, all mutated plants of this type will be collected automatically." When a mutation comes in, you see the "Mutated crops harvested!" notice.

44. Plant Research Module upgrade requirements and costs

The in-game description reads "Unlock this RV item to increase mutated crops in your Home. Level it up to increase variety of mutated crops and mutation probabilities."
The Lv. 1 text says "Chance of Giant crop mutations increased" and Lv. 2 says "Chance of Giant and Colorful crop mutations increased", but the odds of those types don't go up at Lv. 1 or 2. The odds actually rise at Lv. 3 and Lv. 4.
Mutated plants are worth many Home Index points, so raising the Module to Lv. 4 also makes it easier to collect Index points and Modification Toolkit rewards.

55. Mutation odds of the Harvest Moon Festival Moondew Crops (10/16 update)

The 10/16 update gave Moondew Radish and Waxing Moon Pepper their own base chances. Other crops have a base chance of only 0.05% for Huge, but the Moondew Crops have a chance for all 8 types from the start.
So even without a Plant Research Module, Colorful, Shining and Crystalline mutations can appear, and the chance of a mutation each time you harvest is 0.535% (about 1 in 187). At Module Lv. 4 it is 0.89% (about 1 in 112).
The extra chance added by Module level is the same as for other crops (each cell in the table = the Moondew Crops' base chance + the Module's extra chance from the table in section 2). The four-star "Huge Colorful Shining Crystalline Moondew Radish" and "Fullmoon Pepper" are 0.005% without a Module and 0.01% at Lv. 4.
The Harvest Moon Festival ends on 10/28 at 05:00. Actual results may differ.

Odds per mutation type for Moondew Radish and Waxing Moon Pepper (the same for both)

Mutation type	Lv. 0	Lv. 1	Lv. 2	Lv. 3	Lv. 4
