However, there are few field-scale studies that could aid in predicting the potential risks to rice yield and developing countermeasures against yield losses. Therefore, this study was carried out to iden-tify the effect of high temperature on pollen fertility and spikelet sterility in improved rice genotypes and to assess the heat tolerance genotypes among the improved rice varieties during 2016 summer rice sea-son with twelve improved rice varieties in the field of Department of Plant Breeding, Physiology and Ecology with Randomized Complete Block design. The tested varieties were sown three different times to ensure engaged with high temperature stress at flowering time. The microclimate, pollination and spikelet sterility were examined. During observation periods the maximum air temperature was more than 35 °C, at that time the relative humidity was reduced (19-32 %) with high wind speeds (2–4 m s-1). Under such condition, there was supported microclimate for stable pollination even the temperature more than 35 °C. The average duration of high temperature above 35 °C was around 8 hours. Similarly the average nighttime temperature (7:00 pm – 7:00 am) was ranged 27-32 °C. Among tested genotypes, Thu Kha Yin, Shwe Thwe Yin, Zi Yar 9 and Shwe Ma Naw had higher seed set percentage (around 58-75 %). The results revealed that these four genotypes were promising genotypes for future breeding pro-gram related to heat tolerance"}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "Rice"}, {"interim": " High temperature"}, {"interim": " Relative humidity"}, {"interim": " Pollination"}, {"interim": " Spikelet sterility"}]}, "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": "Saw BoDay Shar (87-94).pdf", "filesize": [{"value": "862 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 862000.0, "url": {"url": "https://meral.edu.mm/record/22/files/Saw BoDay Shar (87-94).pdf"}, "version_id": "490e2e5d-55f1-4235-bb5f-5519f32e1791"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_journal_title": "Yezin Agricultural University", "subitem_volume": "6"}]}, "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": "Shar, Saw Bo Day"}, {"subitem_authors_fullname": "Htun, Than Myint"}, {"subitem_authors_fullname": "Htwe, Nyo Mar"}, {"subitem_authors_fullname": "Oo, Aung Naing"}, {"subitem_authors_fullname": "Win, Soe"}, {"subitem_authors_fullname": "Aung, Mie Mie"}]}]}, "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": "2019-12"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "https://yauor-yau.archive.knowledgearc.net/handle/123456789/254"}, "item_title": "Influence of Temperature and Relative Humidity on Pollen Germination and Spikelet Sterility in Improved Rice Varieties", "item_type_id": "21", "owner": "1", "path": ["1582969126285"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000000022", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-03-05"}, "publish_date": "2020-03-05", "publish_status": "0", "recid": "22", "relation": {}, "relation_version_is_last": true, "title": ["Influence of Temperature and Relative Humidity on Pollen Germination and Spikelet Sterility in Improved Rice Varieties"], "weko_shared_id": -1}
