Crop Mutation

Fruit and vegetable crops make up the majority of the mutations in Harvest Moon: One World. Each family is made up of a parent crop and its 7 mutant children. Growing the fruits and vegetables in the proper field and season can trigger a mutation. Selling a specific number of the mutated variety will unlock the seeds in select vendor shops.

Cabbage

Onion

Tomato

Strawberry

This berry has several Harvest Wisps in the little alcove along the road from Lebkuchen to Salmiakki, just a bit north of the Lebkuchen mine. The parent fruit doesn't sell for a lot, but once the mutations start to trigger, the Strawberry family becomes the favorite crop of many One World farmers to sell for profit.

Strawberry takes 6 days to mature, regrows in 3 days, and can be harvested three times.

Corn

Wheat

This grain is used in a lot of cooking recipes such as meuniere, breads, and cakes. There are several Harvest Wisps for wheat such as three wisps in the large alcove between Lebkuchen and the Pastilla desert, or two wisps in the small alcove where the Speckled Bear is on the path to the lava field. There is another wisp point behind the ruined castle, by Shogen and Sana's house, and and near the red Torii gate on Wagashi island.

Wheat takes 4 days to mature and can only be harvested one time.

Rice seeds do not appear in any store, but Rice Harvest Wisps are plentiful around Wagashi. Rice and Lava Rice appear in the game when you purchase the separate Far East Adventure DLC.

Potato

There are a few places where you can find wisps that hand over Potato seeds. There is one in the apple grove just north of the farm in Calisson. There's another on the road leading from Mom's house towards Calisson, just a little bit up the path from Mom's. A third is on the eastern side of the livestock fence at Braden's farm.

Potatoes take 6 days to mature, regrows in 3 days, and can be harvested three times.

The Harvest Wisps that hold Spinach Seeds are around the Lebkuchen area. There's one in Tristan's farm area, and another in the large clearing past the Lebkuchen farm area. There is another one south of Lebkuchen, at the little alcove with 1 field square. Another is in the area between the Salmiakki Lake and the Salmiakki Mountaintop. One more is on the Wagashi farm area, close to the Sparky machine.

Spinach takes 3 days to mature and can only be harvested one time.
