Abstract
由八個不同地區蒐集之台南白玉米族群，經自交分離至S2及S5世代自交系，經由田間人工接種檢定結果，顯示所分離的自交系間，不論在輪生期或開花期對亞洲玉米螟(Ostrinia furnacalis)之抗性具有明顯之遺傳變異存在，在大量自交系統中可獲得輪生期及開花期皆具有抗性之自交系。
The S2 and S5 inbred lines derived from eight Tainan-white (TNW) maize populations collected from eight differential areas were evaluated for resistance to Asian corn borer (Ostrinia furnacalis), at Wufeng, Taichung. Artificial infestation of the larve on plant was used in whorl and silking stages of plant development, respectively. The result indicated that the TNW inbred lines with larger genetic variation for Asian corn borer feeding damage in the whorl and silking stages of plant development can be selected for higher resistance.
