The seeds were collected from 23 F1 hot pepper plants grown at Yezin Agricultural University Farm. The experiment was laid out in a Randomized Complete Block design (RCBD) with two replications. Leaf length, leaf width, filament length, corolla length, fruit width, thousand seed weight and number of seeds per pod showed important contributors towards total variation among the genotypes. Variability study on these seven traits highlighted that phenotypic component was the major contributor to total variance. Low and medium heritability values and higher phenotypic coefficient of variation (PCV) suggested that all the above phenotypic traits interacted with the environment rather than genetic variation. Segregation patterns of 21 qualitative traits indicated similar characters for angled stem, erect flower, white corolla and corolla spot, rotate corolla, white filament, elongate fruit, obtuseness of fruit at pedicel attachment and absence of neck at the base of fruit. Segregation distortions observed in some traits: nodal anthocyanin, branching habit, leaf shape, mature fruit color suggested that they are polygenic traits. Calyx margin and fruit bearing characters followed the Mendelian ratio (3:1), highlighting the monogenic recessive nature of the gene. Anther color expressed independent assortment with complete dominance (9:3:3:1). Plant growth habit, stigma exsertion, fruit surface, leaf color and male sterility resulted as modified F2 dihybrid ratios indicating the involvement of two genes controlling each trait. From the breeding point of view, variation in quantitative traits, on which environmental factors have a profound effect, may hinder the progress in selection for progeny containing favorable genes. However, variation in qualitative traits as a result of segregation in F2 progeny might be useful for selection of desirable quality in next generation."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "hot pepper"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-05-05"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "Variation and Segregation,hot pepper, 2017.pdf", "filesize": [{"value": "617 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 617000.0, "url": {"url": "https://meral.edu.mm/record/124/files/Variation and Segregation,hot pepper, 2017.pdf"}, "version_id": "561b022a-de15-413b-b750-b4ceb36fa9c5"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_journal_title": "Journal of Agricultural Research", "subitem_volume": "4;2"}]}, "item_1583103147082": {"attribute_name": "Conference papaers", "attribute_value_mlt": [{}]}, "item_1583103211336": {"attribute_name": "Books/reports/chapters", "attribute_value_mlt": [{}]}, "item_1583103233624": {"attribute_name": "Thesis/dissertations", "attribute_value_mlt": [{"subitem_supervisor(s)": []}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Chaw Su Su Htwe"}, {"subitem_authors_fullname": "Aye Aye Thwe"}, {"subitem_authors_fullname": "Nyo Mar Htwe"}, {"subitem_authors_fullname": "Min Zar Ni Aung"}, {"subitem_authors_fullname": "Khin Thida Myint"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Publication"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Journal article"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2017"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "https://yauor-yau.archive.knowledgearc.net/handle/123456789/69"}, "item_title": "Variation and Segregation in F2 Population of Hot Pepper (Capsicum annuum)", "item_type_id": "21", "owner": "1", "path": ["1582969222431"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000000124", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-03-05"}, "publish_date": "2020-03-05", "publish_status": "0", "recid": "124", "relation": {}, "relation_version_is_last": true, "title": ["Variation and Segregation in F2 Population of Hot Pepper (Capsicum annuum)"], "weko_shared_id": -1}
