Breeding of the New Soybean Variety Tainan No.10

Wu, C.H. and H. L. Huang

Abstract

   Tainan No.10 is a new soybean variety successfully developed by the Tainan District Agricultural Research and Extension Station in May, 2014. During the fall crop season in 2006, Tainan No.10 was cross-bred from 95(1)-4 and Tainan No.2. The generations from F2 to F4 were propagated by applying the bulk method. The F5 generation underwent the plant selection process and the selected plants then went through a series of standard field evaluations according to the official protocols. Tainan No. 10 shows many positive characteristics such as high yields, resistance to powdery mildew, yellow seed hilum, being non-GMO, and high protein content. The number of days required for the maturing of Tainan No. 10 is 101-103 days and 96-98 days in the spring and fall crop seasons, respectively. The height of its plantation is about 59.3-62.2 centimeters for the spring crops and 40.4-43.7 centimeters for the fall crops. The plantation has white flowers and trifoliate oval leaflets. The seed coat, hilum, and cotyledon are all yellow. The dry weight of 100 seeds is 24.8-27.1 grams. Average yield are 2,700-3,800 kg/ha and 2,100-2400 kg/ha in the spring and the fall crop seasons, respectively. Tainan No. 10 has high dry basis protein content of 41%, and is therefore suitable for making food products such as soybean milk, tofu, and miso.
