They have, however, a tendency to be less tolerant to pre-harvest sprouting than red-grained wheat varieties. Pre-harvest sprouting in wheat represents a major constraint to the production of high-quality grain. Thus, it is desired to develop white-grained varieties with high tolerance against pre-harvest sprouting. Red-grained varieties have red seed coats. The ‘R loci' for seed coat color are located one each in the A, B, and D genomes in wheat, which is an allohexaploid crop. Red coat color is dominant and white coat color is a recessive trait. Seed coat color is a Mendelian inheritance trait. If at least one R locus is red grain type, the seed coat color will be red. In addition, the phenotype of the grain color is not identified until one generation later because seed coat is a maternal tissue. Therefore, genetic markers are useful in wheat breeding not only to decide the R loci genotypes of the parents' lines but also to select white-grained segregants efficiently from siblings at the seedling stage.\nThis report introduces a simple, labor-saving method for the genotyping of wheat seed coat color genes, Tamyb10-A1, Tamyb10-B1, and Tamyb10-D1. This method consists of two multiplex PCRs per sample. Multiplex PCR 1 was carried out with five types of primers for genotyping of Tamyb10-A1. Then, multiplex PCR 2 was carried out with four types of primers for genotyping of Tamyb10-B1 and Tamyb10-D1. This is more labor-saving than the method reported previously by Himi et al. (2011), which required five PCRs for each sample.\nFirst, Tamyb10s in four varieties were analyzed by the previous method and this new method. The results showed the same genotypes detected by the two methods. Next, two leading varieties from Hokkaido, “Yumechikara” and “Kitahonami”, with unknown Tamyb10s genotypes, were analyzed by multiplex PCRs. The results showed that their genotypes were R-A1a／R-B1b／R-D1b  and R-A1b／R-B1a／R-D1b, respectively. This new method contributes to selecting white-grained segregants from backcross populations of a white-grained line × “Zenkojikomugi” (a red- grained variety).\nGenotypes of 16 red-grained varieties are shown as examples. The information is useful in making the three genes R-A1a／R-B1a／R-D1a  match to select white-grained lines from siblings with high tolerance against pre-harvest sprouting in wheat breeding.","subitem_description_type":"Abstract"},{"subitem_description":"小麦（Triticum aestivum L.）の種皮色遺伝子Tamyb10の遺伝子型判定は，白粒系統を効率的に選抜するために有用である。Tamyb10の遺伝子型判定には，これまでHimiら（2011）の方法による10種類のプライマーを用いた1検体につき5反応のPCRが必要だった。\n既報の4種類のプライマーと新たに設計した1種類のプライマーの合計5種類のプライマーからなるセット，及び既報の2種類のプライマーと新たに設計した2種類のプライマーの合計4種類のプライマーからなるセットを考案した。これらプライマーセットを用いて1検体につき2反応のマルチプレックスPCRをTうことにより，Tamyb10-A1，Tamyb10-B1，及びTamyb10-D1の遺伝子型を簡便に判定できる方法を確立したので紹介する。","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00002276","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立研究開発法人 農業・食品産業技術総合研究機構"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.24514/00002276","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2432-8073","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"栗原, 志保"},{"creatorName":"クリハラ, シホ","creatorNameLang":"ja-Kana"},{"creatorName":"KURIHARA, Shiho","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"松中, 仁"},{"creatorName":"マツナカ, ヒトシ","creatorNameLang":"ja-Kana"},{"creatorName":"MATSUNAKA, Hitoshi","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-03-25"}],"displaytype":"detail","filename":"05harc-bull-no207p35-.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","license_note":"© 国立研究開発法人 農業・食品産業技術総合研究機構\nNational Agriculture and Food Research Organization, Japan","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"05harc-bull-no207p35-.pdf","url":"https://repository.naro.go.jp/record/2371/files/05harc-bull-no207p35-.pdf"},"version_id":"626fbaed-e241-4c89-bf69-d6a4bd79dab2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"マルチプレックスPCR","subitem_subject_scheme":"Other"},{"subitem_subject":"遺伝子型判定","subitem_subject_scheme":"Other"},{"subitem_subject":"Tamyb10","subitem_subject_scheme":"Other"},{"subitem_subject":"種皮色","subitem_subject_scheme":"Other"},{"subitem_subject":"小麦","subitem_subject_scheme":"Other"},{"subitem_subject":"穂発芽耐性","subitem_subject_scheme":"Other"},{"subitem_subject":"Multiplex PCR","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"genotyping","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Tamyb10","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"seed coat color","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"wheat (Triticum aestivum L.)","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"tolerance against pre- harvest sprouting","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":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"マルチプレックスPCRによる小麦種皮色遺伝子型判定の簡便法","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"マルチプレックスPCRによる小麦種皮色遺伝子型判定の簡便法"},{"subitem_title":"A Simple Method for Genotyping of Wheat Seed Coat Color Genes by Multiplex PCRs","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"11","path":["35","370"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-22"},"publish_date":"2019-03-22","publish_status":"0","recid":"2371","relation_version_is_last":true,"title":["マルチプレックスPCRによる小麦種皮色遺伝子型判定の簡便法"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2023-05-15T15:18:08.149728+00:00"}
