Tainan No. 18 is a single cross supersweet corn hybrid and was coded as Nanyu No. 3 before registration. Its pedigree is Sig 2-1-1 × Honey 388-12-1-2. The maternal line Sig 2-1-1 was derived from sigma 666 and characterized with resistances to downy mildew, and stalk rot, early maturity as well as heat tolerance. The paternal line Honey 388-12-1-2 was originated from Honey 388 and endowed with resistances to downy mildew, and rust disease, early maturity and heat tolerance also. Since being selected out in 1987, Nanyu No. 3 had been recommended to participate in regional yield trial, plant density and nitrogen fertilizer test, chemical analysis and sensory evaluation for quality and reaction test on various economic important disease and insect pests. The data collected from the above tests indicated that Nanyu No. 3 is characterized with high-yielding, moderate resistances to downy mildew, leaf blight and rust disease, early maturity and heat tolerance. After evaluation by the meeting of the Committee of Registration for New Crop Cultivar convened by the Department of Agriculture and Forestry, Taiwan Provincial Government, Nanyu No. 3 was finally named as Tainan No. 18, in October 1990. Tainan No. 18 is an early maturing supersweet corn hybrid and posseses a wide adoptation characteristic. It is suitable to be cultivated in the areas with sandy soil and good irrigation facility.
