中文摘要 | 新育成秈稻品系在田間遭受二化螟蟲為害較低者,進一步在網室以人 工接蟲及室內以稻芽飼育幼蟲結果均顯示較台中秈10號具抗蟲特性。其抗蟲原 因可能與供試品系莖稈之矽酸含量較高,稈莖的外徑較小,第三節間長度較短有 關。供試品系之米質優良,稻穀產量除台秈育368號及台秈育1577號比對照台 中秈10號稍低外,台秈育1354、1744、2154號及台秈糯育2143號均比對照高, 深具命名推廣潛力。 |
英文摘要 | The characteristics of rice stem may affect the resistance to stem borer. In this study the silica content in stems and external diameter in culm of newly developed Indica rice lines which resistance to stem borer at cage and field feeding tests were analysed. It was selected lower precentage of dead heart of tested lines than that of Taichung Sen 10. It showed that tested lines were more resistant to stem borer than Taichung Sen 10. They were due to higher silica content at stem, larger external diameter of culm and larger length of the 3rd elongated internodes than Taichung Sen 10. Tested lines all have good rice quality. The grain yield of Tai Sen 1354, 1744, 2154 and Tai Sen (waxy) 2143 were higher than that of Taichung Sen 10. |
