中文摘要 | 1985∼1990年間,於網室條件下,利用集體檢定法以帶毒褐飛蝨接種 總計794個水稻品種(系)及野生稻對萎凋矮化病之抵抗性。檢定結果供試501個 秈稻品種(系)中顯示極抗級(罹病率0∼10%)反應者計有IR226-464-2、PC-5、台 秈育1168號、台秈糯試14號,19號、台秈糯育7號,10號及14號、高雄秈育 351號、Blue Bell、台秈育1153號,1176號、台秈糯育1157號,1161號,1162 號及1168號、高雄秈育355號、白殼埔占、烏占、嘉義烏占及下腳烏占等21個 品種(系),其中前9個品種(系)在重覆2次檢定中均未發病。供試秈稻品種(系) 中呈抗級(10.1∼20%)反應者計有15個。供試292個梗稻品種及3個野生稻則全 數呈感病性(40∼100%)反應。 |
英文摘要 | During 1985 to 1990, a total of 794 entries of Oryza Spp. rice varieties, and selections were indexed at seedling stage by mass screening method using the viruliferous insect vectors, Nilaparvata lugens Stal for their resistance to rice wilted stunt under screening house conditions. The results indicated that 21 out of 501 Indica type rice varieties or lines, including IR226-464-2, PC-5, Blue Bell, Tai-Sen-Yu 1168, Tai-Sen Glutinous Shyh 14, 19, Tai-Sen Glutinous Yu 7, 10 and 14, Kaohsiung-Sen Yu 351, Tai-Sen-Yu 1153, 1176, Tai-Sen Glutinous Yu 1157, 1161, 1162 and 1168, Kaohsiung Sen Yu 355, Pai-Ko-Pu-Chan, Wu-Chan and Chia-Yi-Wu-Chan, reacting as highly resistant with infection levels below 10 percent. Among them, the former 9 varieties or lines were completely free from infection. Fifteen varieties or lines reacted as resistant with infection levels between 10.1-20%. All 292 Japonica type rice varieties or lines and 3 wild rice varieties were all found suceptible to rice wilted stunt with infection levels of 40.1-100%. |
