Nine males were mated with thirty females according to a hierarchial mating system. Eggs of twenty-one lots which had over 20% hatchability were used for examination of hatching time and duration of hatching. Parental stock used had been imported from Oregon, U.S.A. as eyed eggs and raised at a freshwater fish farm in Japan. Hatchability varied from 0 to 91.3% with mean value of 46.2%, being under 10% in nine out of thirty lots. The size of female, mean egg weight, egg density in iucubator and position of incubator showed no significant effect on hatchability. At least one lot within a sire had over 50% hatchability. A great fluctuation was observed in hatching time even in the same lot and duration of hatching ranged 6 to 21 days. Mean hatching time and mean degree-days (Centigrade) were in the ranges of 65 to 69 days and 476 to 516, respectively. The analysis of variance of half-sib showed that differences in hatching time among sires and among dams within sires were significant at 1% level. Based on the sire and the dam component, heritabilities for hatching time were estimated to be 0.261 and 0.511 respectively. These values suggest that additive genetic variance forms about one-fourth of phenotypic variance and maternal effect is 0.063.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"養殖研究所","subitem_publisher_language":"ja"}]},"item_10002_radio_30":{"attribute_name":"item_10002_radio_30","attribute_value_mlt":[{"subitem_radio_item":"吉田","subitem_radio_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"nria_k_1_21","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本農学文献記事索引(agriknowledge)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010230726","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00245945","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0389-5858","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐藤, 良三","creatorNameLang":"ja"}],"familyNames":[{"familyName":"佐藤","familyNameLang":"ja"}],"givenNames":[{"givenName":"良三","givenNameLang":"ja"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"coho salmon; hatching; heritability.","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ギンザケの系統内におけるふ化率とふ化日数の変異およびふ化日数の遺伝率の推定","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ギンザケの系統内におけるふ化率とふ化日数の変異およびふ化日数の遺伝率の推定","subitem_title_language":"ja"},{"subitem_title":"Variations in Hatchability and Hatching Time, and Estimation of the Heritability for Hatchirg Time among Individuals within the Strain of Coho Salmon (Oncorhynchus kisutch).","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716955633551"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-18"},"publish_date":"2024-06-18","publish_status":"0","recid":"2007471","relation_version_is_last":true,"title":["ギンザケの系統内におけるふ化率とふ化日数の変異およびふ化日数の遺伝率の推定"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-03-25T08:43:19.262056+00:00"}
