摘  要

  羅正宗、林國清、侯福分。2009。水稻新品種台南13號之育成。臺南區農業改良場研究彙報54:1-13。

   台南13號原品系名稱為台稉育150號,係本場嘉義分場於民國90年第一期作,以南稉育42號為母本(台南區農業改良場育成之香米品系,外觀米質及食味皆佳,抗稻熱病與褐飛蝨,耐寒性弱。),台農71號為父本(農業試驗所於民國89年育成之香米品種,米粒外觀佳、食味優良,惟植株軟弱容易倒伏,對病蟲害抵抗性欠佳,易穗上發芽。)進行雜交,90年第二期作栽植F1世代植株,於民國91年第一期作至92年第二期作進行F2至F5世代的選拔工作。而後經初級與高級產量比較試驗,及區域試驗與各項特性、病蟲害檢定結果顯示:本品種為一早熟品種;株高較矮抗倒伏性良好;株型優良;外觀米質及食味皆優良,米飯具香味;對葉稻熱病及飛蝨類病蟲具中抗、耐寒性中抗、脫粒性適中及具相當產量等優良特性。於民國98年第一期作經審查委員會審議通過,命名為台南13號。由於本品種具有上述之優良特性,預期新品種將可為農民、廠商及消費者所歡迎,取代部分現有早熟栽培品種面積,對增加農民收益有所助益。

Lo, J. C., G.. C. Lin and F. F. Hou

Abstract

  A newly japonica type rice variety “Tainan 13” was released by Chiayi Branch Station of the Tainan District Agricultural Research and Extension Station in the first crop season of 2009. The variety was derived from a cross between Nankeng yu 42 and Tainung 71, hybridized in the first crop season of 2001. Through eight years breeding processes, including progeny selection, preliminary, advanced and regional yield trials, quality evaluation, panel test, nitrogen response, storage trial and traits screening tests. After evaluation by the Committee of Registration for New Rice Varieties of the Tainan District Agricultural Research and Extension Station. This early maturing variety is characterized with the merits of excellent grains qualities both in its appearance and eating, resistant to rice blast, well response to cold tolerance, suitable shattering rate, resistant to loading and being able to product a high yield.
