Ancestral species

Red Jungle Fowl (RJF)

Origin

♂1 and ♀1 were introduced from Kagoshima Univ. (2004) and ♂2 and ♀4 were from the Wild Avian Reproduction Center in Yamanashi Pref. Co. Ltd. (derived from Kagoshima Univ.) (2004), and then ♂15 and ♀15 were introduced from the same company (2006).

Characteristics

This line was originated from one pair imported from Sumatra Is. (Indonesia) with peacock and mated with fowls derived from Vietnam or Thailand, then maintained as a closed colony more than 20 years.

GRY

Origin

GRY is a closed colony originated from cross-mating among grey jungle fowl (Gallus sonneratti) and red jungle fowl (Gallus gallus), and the Ehime-Jidori (EJ) line.

Characteristics

Grey jungle fowl (GJF) is one of the ancestors of the domestic chicken. However, the crowing and plumage colors are different from that of domestic chickens. GRY birds with GJF-like crowing and plumage colors have been selected for obtaining the next generation. Females of GRY show the lacing-like plumage on the breast, and almost GRY males have a different syllable in crowing from domestic chickens.

GRN

Origin

Characteristics

Green jungle fowl (GRJF) is thought to be one of the ancestors of the domestic chicken. GRJF is the most genetically different from domestic chickens among the four different species of jungle fowls. The GRN birds with GRJF-like crowing, plumage colors and combs are selected for obtaining the next generation. Some GRN birds exhibit a non-cutted single comb and non-wattle.
