Overview

This source is valuable for tracing later colorful multi-lame selections, while noting that independent parent-stock creators deserve their own credit. Documented developer/creator role: JOURAKUAN / 静楽庵.

Recorded lineage inputs

Aurora-derived black selection / White Lame Miyuki

These are historical breeder-reported founder inputs or longer selection stages, not individually sequenced parents. Review the source J02 for its original scope and missing generations.

Known research gaps

  • JOURAKUAN credit for this cross does not transfer creator credit for Wada's White Lame founding line.
  • Exact number of founding mating generations and phenotype fixation are unknown.
  • 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.
