 note = {日本鶏はわが国の貴重な遺伝資源であるにもかかわらず,生産性が低く,その維持を個人愛好家に依存する品種も少なくない。それらの品種の保全においては,遺伝的多様性や集団構造を明らかにすることが必要となる。本研究はマイクロサテライトDNA多型情報から,観賞用品種を中心に解析をおこなった。供試鶏として7品種125羽を用い,マイクロサテライト28座位の分析をおこなった。その結果,愛好家に維持されている観賞用品種であっても,試験研究機関維持集団や銘柄鶏の素材鶏として系統的に維持されている集団と同程度の遺伝的多様性を示すことが明らかとなった。今回分析した7品種すべてに近親交配(正のFIS値)が認められる結果となった。特に蓑曳,蓑曳矮鶏,烏骨鶏は採取地間で遺伝的差異が生じており,DAS系統樹にてサブクラスターが認められた。一方,鶉矮鶏は採取地間の遺伝的差異は認められず,全個体がひとつのクラスターに含まれる結果となった。, Japanese native chickens are valuable genetic resource in Japan ; however, their low productivity limits their industrial use and forces dependence on a personal breeder for their maintenance. To conserve these breeds, it is important to clarify their genetic diversity, relationships, and structure. In this study, microsatellite DNA polymorphisms were used to analyze the genetic relationships and structure among ornamental breeds of Japanese native chickens. A total of 125 individuals of seven breeds, Kurokashiwa, Minohiki, Minohiki-Chabo, Uzura-Chabo, Ukokkei, Chahn, and Issun-Chahn were used in analyses of 28 microsatellite loci recommended by ISAG/FAO. The results showed that ornamental breeds maintained by private breeders showed the same level of genetic diversity compared with populations maintained by institutes or breeding stations. Despite high genetic diversity, significant positive FIS values indicating high inbreeding were estimated for all seven breeds analyzed in this study. Furthermore, genetic differentiation among sampling locations was observed in Minohiki, Minohiki-Chabo, and Ukokkei. While sub-clustered structure was observed in the DAS tree for these three breeds, in Uzura-Chabo, genetic differentiation was not observed and all specimens (including those from different sampling locations) were included in the same cluster., E, 6, KJ00007059045, 論文, Article},
