＜ABOUT PROJECT＞
Started: January 2003
Progress Rating: 3 Finches
（as of March 2006）

＜本件プロジェクトのポイント＞

ジュウシマツのボディーを
①頭部を白色にする（難）
②腹部をベタ塗りにする（難）

考え方：
ヘキチョウの柄を移入
遺伝子：
ヘキチョウ「柄」遺伝子を
ジュウシマツ上でホモ結合
（染色体上の「柄」に関する
塩基部分をヘキチョウ型で
２本ともに揃える
塩基は特定できないが
交配と選抜により組み換える）

現在、ヘキチョウ「柄」遺伝子を
抽出できたと思われるが
ヘテロ結合で隠れた状態（劣性）
ホモ結合を作るための
交配を準備中

セレベス・ヘキチョウ

ヘキチョウの特徴は頭部が白いこと
今回は通常より広い白頭部をもつ
セレベス・ヘキチョウを選びました

同親の２回目産卵のＢＣ１幼鳥２羽
交配計画Ｂの（２）の子供で、
上記と合せて合計３羽になりました

後から生まれた焦茶色が♂です
残りは♀で、姉弟結婚させて
（いいのです！）
交配計画Ｂの（３）に進みます
（１羽は薄茶になりました）

さあ、ここで計画は頓挫中
ＢＣ１♀が死亡。
ＢＣ１は♂２羽のみになって、
姉弟交配ができなくなりました
新しいヒナもとれていません
しばし待ちです

NEW FASION :Project to create White-Headed Society Finch

Let us do it!
A white-headed society finch will be nice,
don't you think?
Studio decided to launch the second big project
to create a new fashion for society finches
through hybrid breeding processes,
just because Studio was so impressed by one picture
of such a cute little bird.

（Blueprint Plan: Touch the picture!）

【INSPIRED BY ONE PICTURE】

The story began when one exciting photograph was sent
from Kanji Kawabata, the breeding scientist of Society Finch
and the author of Invitation to Bengalese Finch
(an excellent web site). The picture was about
a hybrid bird (introduced in Kanji's web site) bred by
Mr. Yokouchi who succeeded to import "Ino" gene into
a White-Headed Munia. Its cream color is so cute!

A white headed bird is very impressive. It also reminds us
of a white-headed eagle soaring in the sky.
Anyway, the picture is still about a white-headed nun and not
about a society finch. Is there any society finch with the white
headed style? If coloring allocation of a nun is transferred
to a society finch, it can be done. With a bigger tale,
a nice long courtship song of male, and sweet pastel colors,
it seems a perfect new fashion finch.

【A GENE OF WHITE-HEADED MUNIA】

Thrilled with the idea, Kaz, the designer at Studio,
draws the breeding plan shown below, and says,
"Let us go! Be a challenger!".
A female cream-ino society finch will be paired with a male nun.
It is going to be an inter-species or inter-cultural marriage
between a domestic bird and a wild bird. We will be able to see
a hybrid white-headed finch at the generation of great-grandchildren.
It will be the shortest cut for the goal.

【THE DAY AFTER】

Building a new residence for the cuople is the first thing
to be done. Then to move them in. A white-headed nun just
imported from the wild looks like a "beast" being married with
"beauty", a lady society finch! There happens to start
the musical, so it seems! This story will be reported
with pictures on this page from time to time.
So stay with us.
（Dated: 2003.01.01)

Well, it was the start of the project, which eventually faced
against a lot of unexpected mishaps. In reality, the "beauty"
was much wilder than the "beast"(!) and the shy "beast" never
got along with the cream-ino society finch with red eyes
which do not exist in wild forests! The marriage between
the white-headed nun which we chose and a cream-ino society
finch had failed. However, the story continued.
Having second thoughts, a black-eye normal society finch
was moved into the residence. This time it worked.
They fell in love and had a baby finch!

Being different from the origial plan, the first generation finches
do not have any ino genes. Therefore the process for pastel colored
white-headed society finches becomes much longer now (shown below).
Studio never gives up. We have good news then ---
The baby finch born between the normal society finch and the nun
turns out to be male; that means we have a fertile bird ready
to step forward ((2) of Breeding Plan (B)).

【SLOWLY AND STEADILY】

Um....it is tough to deal with living creatures, of course.
The paticular pair does not seem to be fertile, so that the project
has been temporarily suspended.
The generation after a hybrid crossing is marked as "F1"
and only cocks can be fertile. Then the next crossing between a F1
hybrid bird and a pure society finch gives the "BC1" generation.
Only a half of the BC1 hens are fertile and breeding for fixed type
is yet imcomplete. Since the recessive phenotype does not appear
at this BC1 generation, the shortest cut to get a recessive phenotype
is to cross between the BC1s. The project stops at this stage
of crossing because of the pairing problem.

Studio believes, after careful observations and thoughts, there is
a "white-head gene" being inherited from White Headed Munia
and crossings can be successfully done.
Studio also knows there may be a lot of hereditary troubles involved
in hybrid crossings. It cannot be fast, but it should be done
slowly and steadily to achieve the goal.
We will do our best so that we can deliver good news to you!
