In this study some morphological and physiological characteristics of the plants were investigated both for the markers used for classifying the two varieties, i.e., var. assarnica and var. sinensis of Camellia sinensis and for use as breeding materials. Remarkaule differences were observed between the two varieties in the color of the mature leaf, pubescence of young leaf, cold hardiness and caffeine and tannin contents. In terms of contens of chemical components such as caffeine and tannin, a decreasing cline was observed from India, Bangladesh and Myanmar to mainland China and to Japan. The heritability values of the resistance to tea anthracnose were estimated to range from 0.73 to 0.86 and almost all the tea plants originating from foreign countries were resistant to this disease. In Japan, native plants belonging to the var. sinensis displayed large variations in the disease severity and the plants collected from the southern Kyushu districts showed a high rate of resistance to the disease. It was assumed that they had been selected through cultivation under high temperature and heavy rainfall conditions which promote the infeclion. An effective artificial testing method for tea gray blight caused by the fungus、Pestalotiopsis longiseta was developed in this study. The inheritance of the resistance to the disease was analyzed using many cross combinations by this method. Genetic analysis revealed that the resistance to tea gray blight caused by P. longiseta was controlled by two independent dominant resislance genes Pl_1, and Pl_2. The gene Pl_1 which confers a high level of resistance is genetically epistatic in relation to the Pl_2 gene which confers a moderate level of resistance. The phenolype and genotype of the resislance to tea gray blight were very simple in the Assam plants (var. assamica) and almost all the tea plants showed a high level of resistance with homozygosity of the Pl_1 gene which controls a high level of resistance. On the conlrary, Japanese native plants showed a wide variation in the resistance to this disease and introduced China plants belonging to the var. sinensis showed a resislance intermediale between that of the Assam plants and Japanese native plants. The phenotypes and genotypes related to the resistance to tea gray blight of 88 major cultivars in Japan were identifyed in this sludy. The gene (Pl_1) conferring a high level of resistance to the Japanese cullivars was mainly derived from plants introduced from foreign countries、contributing to the breeding for resistance to tea gray blight in Japan. It is considered that the results obtained in this study in relation to the variations and genetic diversity are fully applicable to the genetic resources of tea in Japan.\n","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00001482","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"独立行政法人 農業技術研究機構"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.24514/00001482","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1346-6984","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":"武田, 善行"},{"creatorName":"タケダ, ヨシユキ","creatorNameLang":"ja-Kana"},{"creatorName":"TAKEDA, Yoshiyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"2814","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"20414667","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=20414667"},{"nameIdentifier":"read0004548","nameIdentifierScheme":"researchmap","nameIdentifierURI":"http://researchmap.jp/read0004548"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-03-16"}],"displaytype":"detail","filename":"nivts_report_No1p97-180p.pdf","filesize":[{"value":"11.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nivts_report_No1p97-180p.pdf","url":"https://repository.naro.go.jp/record/1524/files/nivts_report_No1p97-180p.pdf"},"version_id":"5e406190-4bc8-4a95-992b-e8d1f621ce90"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"tea","subitem_subject_scheme":"Other"},{"subitem_subject":"Camellia sinensis","subitem_subject_scheme":"Other"},{"subitem_subject":"genetic resources","subitem_subject_scheme":"Other"},{"subitem_subject":"gray blight","subitem_subject_scheme":"Other"},{"subitem_subject":"Pestalotiopsis longiseta","subitem_subject_scheme":"Other"},{"subitem_subject":"genetic analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"catechin","subitem_subject_scheme":"Other"},{"subitem_subject":"caffein","subitem_subject_scheme":"Other"},{"subitem_subject":"tea","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Camellia sinensis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"genetic resources","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"gray blight","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Pestalotiopsis longiseta","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"genetic analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"catechin","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"caffein","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":"わが国チャ遺伝資源の多様性とその育種への利用に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"わが国チャ遺伝資源の多様性とその育種への利用に関する研究"},{"subitem_title":"Studies on Variations in Genetic Resources of Tea in Japan and Application to Tea Breeding","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"12","path":["312"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-03-22"},"publish_date":"2019-03-22","publish_status":"0","recid":"1524","relation_version_is_last":true,"title":["わが国チャ遺伝資源の多様性とその育種への利用に関する研究"],"weko_creator_id":"12","weko_shared_id":12},"updated":"2023-05-15T23:13:17.011563+00:00"}
