However, little is known about the relationship between the parents' genetic relatedness and biparental inbreeding depression in their progeny in natural populations. This study assesses the effect of kinship between parents on the fitness of their progeny and the extent of spatial genetic structure in a natural population of Rhododendron brachycarpum. Methods Kinship coefficients between 11 858 pairs of plants among a natural population of 154 R. brachycarpum plants were estimated a priori using six microsatellite markers. Plants were genotyped, and pairs were selected from among 60 plants to vary the kinship from full-sib to unrelated. After a hand-pollination experiment among the 60 plants, offspring fitness was measured at the stages of seed maturation (i.e. ripening) under natural conditions, and seed germination and seedling survival under greenhouse conditions. In addition, spatial autocorrelation was used to assess the population's genetic structure. Key Results Offspring fitness decreased significantly with increasing kinship between parents. However, the magnitude and timing of this effect differed among the life-cycle stages. Measures of inbreeding depression were 0.891 at seed maturation, 0.122 (but not significant) at seed germination and 0.506 at seedling survival. The local population spatial structure was significant, and the physical distance between parents mediated the level of inbreeding between them. Conclusions The level of inbreeding between individuals determines offspring fitness in R. brachycarpum, especially during seed maturation. Genetic relatedness between parents caused inbreeding depression in their progeny. Therefore, biparental inbreeding contributes little to reproduction and instead acts as a selection force that promotes outcrossing, as offspring of more distant (less related) parents survive better.","subitem_description_type":"Abstract"}]},"item_6_description_30":{"attribute_name":"資源タイプ（コンテンツの種類）","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_6_description_5":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Annals of Botany. 105(4):637-646 (2010)","subitem_description_type":"Other"}]},"item_6_link_67":{"attribute_name":"WoS","attribute_value_mlt":[{"subitem_link_url":"http://gateway.isiknowledge.com/gateway/Gateway.cgi?&GWVersion=2&SrcAuth=ShinshuUniv&SrcApp=ShinshuUniv&DestLinkType=FullRecord&DestApp=WOS&KeyUT=000276544200025"}]},"item_6_publisher_4":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"OXFORD UNIV PRESS"}]},"item_6_relation_47":{"attribute_name":"PubMed","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"20202970"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://pubmed.ncbi.nlm.nih.gov/20202970/","subitem_relation_type_select":"PMID"}}]},"item_6_relation_48":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"10.1093/aob/mcq018"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1093/aob/mcq018","subitem_relation_type_select":"DOI"}}]},"item_6_source_id_35":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0305-7364","subitem_source_identifier_type":"ISSN"}]},"item_6_source_id_40":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00532275","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Hirao,  Akira S."}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2015-09-25"}],"displaytype":"detail","filename":"Kinship_parents_reduces_offspring_fitness.pdf","filesize":[{"value":"402.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Kinship_parents_reduces_offspring_fitness.pdf","url":"https://soar-ir.repo.nii.ac.jp/record/10354/files/Kinship_parents_reduces_offspring_fitness.pdf"},"version_id":"fb982b04-a6ff-4c5b-a528-50e5e6e7d5c4"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Biparental inbreeding depression","subitem_subject_scheme":"Other"},{"subitem_subject":"genetic structure","subitem_subject_scheme":"Other"},{"subitem_subject":"germination rate","subitem_subject_scheme":"Other"},{"subitem_subject":"Rhododendron brachycarpum","subitem_subject_scheme":"Other"},{"subitem_subject":"seed maturation","subitem_subject_scheme":"Other"},{"subitem_subject":"selfing rate","subitem_subject_scheme":"Other"},{"subitem_subject":"survival rate","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Kinship between parents reduces offspring fitness in a natural population of Rhododendron brachycarpum","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Kinship between parents reduces offspring fitness in a natural population of Rhododendron brachycarpum","subitem_title_language":"en"}]},"item_type_id":"6","owner":"1","path":["1017"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-11-12"},"publish_date":"2010-11-12","publish_status":"0","recid":"10354","relation_version_is_last":true,"title":["Kinship between parents reduces offspring fitness in a natural population of Rhododendron brachycarpum"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-12-14T04:13:43.345306+00:00"}
