Abstract
於2002年第2期作由臺中區農業改良場以具有越光親緣之臺稉育47359號與越光/臺中秈3號之F_1進行雜交，其後裔經苗栗區農業改良場以譜系法選出，於2005年第2期作晉昇高級產量比較試驗，並參加2006年各項特性檢定後，進入2007年組區域試驗及各級特性檢定。完成各項試驗之結果顯示：苗栗2號米飯食味與臺稉9號相當，在區域試驗各區表現，除東部地區產量較低於臺稉9號外，西部地區的表現則均較優，尤其北部地區在第1、2期作增產率分別高出3.2及18.8%。綜合稻穀產量、稻米品質及氮素施用效益等因素，其合理化氮素施用量為120 kg/ha。
The objective of rice breeding had emphasized on its quality, especial for Miaoli area. The Miaoli District Agricultural Research and Extension Station announced a new high eating quality rice variety, ＂Miaoli 2＂, which is suitable for local cultivation. Its yield was obviously higher than the regular check variety in the northern part, Tai-keng 9, 3.2% and 18.8% in the first season crop and the second season crop, respectively. The reasonable amount of nitrogen application was recommended 120 kg/ha when its grain yield, rice quality, and efficiency of nitrogen utility were concerned.
