Picture gene & lineage tree
Visual pedigree of breeder-reported inputs, where available. Dashed arrows represent documentary claims or selection history, not DNA-tested genes.
This strain's direct parent lines are not established by the reviewed sources. No breeding cross, genotype or inheritance pattern is implied. Source: Sources remain under review; ancestry connections will appear only with cited evidence.

Overview
The historical record explicitly lists two creators for near-contemporaneous Yellow Miyuki expressions, rather than a single claimed inventor or partnership. Documented developer/creator role: JOURAKUAN and Tsutomu Moriguchi — independent origins.
Claim-by-claim evidence
| Research finding | Evidence class | Direct references |
|---|---|---|
| The historical catalog places Yellow Miyuki under 2014 | Historic attribution and catalog year | J02 ↗ |
| It credits JOURAKUAN (Okayama) and Tsutomu Moriguchi (Tokushima) as independent discoverers | Explicit dual-origin credit | J02 ↗ |
| The described phenotype combines Miyuki-type exterior light with yellow pigment | Catalog phenotype description | J02 ↗ |
| Aurora-line breeding is mentioned but direct parent-pair identities are not supplied for both independent lines | Incomplete crossing evidence | J02 ↗ |
Evidence labels refer to documentary strength. They do not assert independently tested genetics.
Known research gaps
- Do not assert the two independently produced lines share the same recent named genetic parent pair.
- Yellow Miyuki is a documented phenotype group; Moriguchi's Akari has its own article and must not be counted as a newly invented duplicate here.
- DNA-confirmed ancestry, Mendelian segregation, complete parent-pair registers and strain-specific water requirements are not established.
- Images from magazine, breeder sites and shop listings are not republished without verified reuse permission.
