Abstract
臺農2號為單雜交種，屬於青割玉米，其母本及父本自交系分別為SW558及TA3651-377。母本係由泰國Kasetsart大學引進之抗露菌病種源Suwan-1 DMR經自交分離育成，屬硬粒種，莖葉茂盛，抗普通型鏽病、煤紋病及露菌病；父本TA3651-377係由美國夏威夷大學引進之自交系Hi31經純化選出者，屬馬齒種，一般組合力高，對露菌病及媒紋病有抗性，且具有強稈抗倒伏之特性。Tainung No. 2 is a single-cross hybrid. Its parental inbreds are SW558 and TA3651-377. The maternal parent SW558 is a flint selected from the progenies of suwan-1 DMR which come from Thailand kasetsart University via inbreeding. SW558 is resistant to common rust, H. turcicum leaf blight and downy mildew, when it was screened under growth chamber conditions. The paternal parent TA3651-377 is a U. S. dent selected from the purified lines of Hi31, which was introduced from Hawaii University. TA3651-377 has high general combining ability (GCA) and is resistant to downy mildew and H. turcicum. Tainung No. 2 possesses 50 metric ton/ha forage yield potential, when harvest from dough to physiological maturity stages.
