Recently, a reduction in population size and in genetic diversity were detected in this breed. In this study, ISAG/FAO recommended 30 microsatellite markers be used to investigate temporal change in genetic diversity and phylogenetic relationships among Ryujin-Jidori and other Japanese native chicken breeds. The Ryujin-Jidori samples were collected in 1994 (n=12) and 2007 (two populations, n=18, 7), respectively. In this analysis, twelve monomorphic loci were observed. Allele loss at five loci and shift of major allele (allele frequency>0.5) at six loci were also observed. In other loci, number of alleles ranged from two to three. Mean number of alleles (MNA) and average expected heterozygosity (H^E) of Ryujin-Jidori populations were lower than previously reported in other Japanese native chicken breeds. No significant difference in MNA was observed between the two Ryujin-Jidori populations. However, a temporal decrease over time in H^E was observed. On the neighbor joining dendrogram based on D^A genetic distance, the Ryujin-Jidori populations were sepa- rated from all other breeds (Gifu-Jidori, Tosa-Jidori, Shokoku and Shamo) with robust bootstrap value. Therefore, it is suggested that Ryujin-Jidori is a unique and valuable genetic resource for Wakayama prefecture. However, to keep Ryujin-Jidori in small population could lead to an affect of genetic drift, intensify inbreeding and decrease genetic diversity.","subitem_description_type":"Other"}]},"item_1_description_13":{"attribute_name":"レポート・講演番号","attribute_value_mlt":[{"subitem_description":"E","subitem_description_type":"Other"}]},"item_1_description_15":{"attribute_name":"表示順","attribute_value_mlt":[{"subitem_description":"8","subitem_description_type":"Other"}]},"item_1_description_16":{"attribute_name":"アクセション番号","attribute_value_mlt":[{"subitem_description":"KJ00005352366","subitem_description_type":"Other"}]},"item_1_description_8":{"attribute_name":"記事種別(日)","attribute_value_mlt":[{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1_description_9":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_1_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00164184","subitem_source_identifier_type":"NCID"}]},"item_1_text_6":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"東京農業大学農学部
