Beginning in 1960, Puzih substation, formerly the Corn Research Center, released forage maize Tainan No.5, an early-maturing variety with uniform ears also suitable for baby-corn production. In 1971 we introduced Tainan No.11, early-maturing and resistant to downy mildew. Tainan No.16, released in 1984, is a mid-maturing, high-yielding variety with downy-mildew resistance and drought tolerance. In 1998 we released Tainan No.20, a mid-late maturing, high-yielding variety resistant to downy mildew, rust, and viral diseases, lodging- and breakage-resistant, and suitable for mechanical harvest; in 2009 Tainan No.24 improved on those traits with enhanced rust resistance and harvest suitability. Nan dares No.29, released in 2017, is a hard-endosperm maize combining disease resistance, labor savings, and cold tolerance for mechanized cultivation, followed in 2018 by Tainan No.30, which adds drought tolerance. In 2024 we introduced Tainan No.31 and No.32, both high-protein, high-yielding, stress-resilient lines containing 8.8 % protein, ideal for flour milling.

For sweet corn, Tainan No.18 debuted in 1990 with high yield, quality, leaf-spot resistance, and heat tolerance for year-round cultivation; Tainan No.26 in 2011 added rust and lodging resistance; Tainan No.27 in 2013 became the first yellow-and-white bicolor sweet corn with strong disease and pest resistance suited to Taiwan’s summers; and Tainan No.28 in 2018 further strengthened plant vigor and pest resistance.

Our white-kernel lines include Tainan No.22 released in 2000, a compact, uniform plant with thin pericarp and excellent flavor, and Tainan No.23 released in  2007, a glutinous white corn with robust growth, strong disease resistance, and yields of 13,500 kg/ha of fresh husked ears with a thin, tender, Q-textured kernel; Tainan No.25, released in 2010, is a high-yielding, quality black glutinous corn with vigorous plants.
