Japan's farm ministry has opened consultation on the rulebook that will decide which new crop varieties can be designated "important" under a law passed this year. The draft basic policy, put out for comment on September 8, spells out how officials will interpret that statutory label under the Act on Promotion of Breeding of Important Varieties and Production of Their Seeds and Seedlings (Act No. 71 of 2026).
To qualify, a variety has to clear three separate tests. It needs at least one of four trait categories: suitability for mechanized sowing, cultivation and harvest work, including direct seeding or fruit set without pollination; higher or more stable yield, including better processing yield; heat tolerance or pest and disease resistance that offsets climate-driven damage; or another trait addressing shifting farm conditions. Its seeds or seedlings must also be free to reach at least two prefectures, meaning breeder's-right licensing, trademark deals, sales contracts or seed secrecy cannot be used to bottle supply into a single region. And the variety must already hold formal registration under the Seed and Seedling Act.
| Criterion | Requirement |
|---|---|
| Trait | At least one of four categories: labor-saving (mechanized work, direct seeding, fruit set without pollination), higher or more stable yield, climate resilience (heat tolerance, pest/disease resistance), or another trait responding to changing farm conditions |
| Distribution | Seeds or seedlings must be able to reach at least two prefectures; breeder's-right licensing, trademark deals, sales contracts or seed secrecy cannot be used to restrict supply to a single region |
| Registration | The variety must already hold formal registration under the Seed and Seedling Act |
Clearing that test does not, by itself, unlock money. The draft reserves the actual payoff, preferential treatment such as priority selection in national budget programs, for certified breeding operators and certified seed-production activity implementers whose approved plans target a qualifying variety. The ministry's own ambitions for that certified tier are modest: certified breeding operators are meant to produce 35 qualifying varieties, and certified seed producers to be multiplying seed for 35 important varieties, both by 2030.
Comments, accepted in Japanese only, are due October 7 through the e-Gov portal under case No. 550004401, or by mail to the ministry's research council secretariat in Tokyo. The draft implements Article 5 of the law, filling in the details of how the framework will operate in practice.
