中文摘要 | 軟性質地之長秈米,在臺灣已有廣大的消費群眾,由於主要的栽種品種為臺中秈10號,對水稻白葉枯病之抵抗性較弱,種植期間容易罹病而影響稻米產量及品質,為增進稻米之生產效益,改善臺中秈10號對白葉枯病之抗病性視為一項重要工作。臺秈2號(原品系名稱為臺秈育3165號)係於民國79年第一期作以臺中秈10號為母本,與具有抗白葉枯病之香糯品系臺秈糯育738號雜交,再與臺中秈10號回交一次之雜交組合,於民國81年第二期作選出。經過各級產量試驗,全省性區域試驗及各項特性之檢定結果顯示,本品種具有高產與抗病之特性,稻穀產量與臺中秈10號相比較,一期作增產3.5%,二期作增產7.3%。對稻熱病、白葉枯病及縞葉枯病並具有良好的抗性。臺秈2號兼具有優良的米質與地區之廣適應性,適合本省秈稻區一、二期作及中間作栽培,本品種於87年第一期作申請登記命名,並獲通過開始推廣。 |
英文摘要 | Taichung Sen No. 10 has been the leading indica rice variety in Taiwan, however, it is susceptible to bacterial leaf blight, especially after typhoon. In oder to improve the disease resistance for Taichung Sen No. 10, a cross combination between Taichung Sen No. 10 and Taisen Glutinous Yu 738 was made in the spring of 1990, and the F1 plants were back cross to Taichung Sen No. 10 in the fall of 1990. After a series of experiments and observations, a breding line with good characteristic was selected in the fall of 1992, which was designated as Taisen Yu 3165. This breeding line with others were joined yield trials and agronomic characteristic tests, including the regional yield trical, Taisen Yu 3165 performed good in plant type, disease resistance and grain yield. Based on the 2 years average of regional yield trials, Taisen Yu 3165 obtained 3.5% and 7.3% higher yield than the Taichung Sen No. 10 for the spring and fall crop respectively. The data collected from the agronomic characteristic tests showed that Taisen Yu 3165 is resistant to leaf blast, panicle blast, rice stripe disease and moderately resistant to bacterial leaf blight. The other agronomic characteristics of Taisen Yu 3165 were similar to Taichung Sen No. 10. This variety was formally named as Taisen No. 2 in 1998. Thus, it is recommended to plant this new rice variety in the area which is suitable for indica rice varieties to grow. |
