A high starch maize hybrid ＂Jinongda 115＂ was accomplished using ＂KM36＂ with female parent and ＂KM12＂ with male parent. Its yield was 10 285.1 kg/hm^2 in the 2-year regional test, 13.6% higher than that of the control variety ＂Sidan 19＂ ; And its yield was 10 168.1 kg/hm^2 in the production test, 9.7% higher than that of the control variety ＂Sidan 19＂. ＂Jinongda 115＂ was examined and ap- proved by National and Jilin Evaluation Committee of Crop Variety in January of 2007. ＂Jinongda 115＂ is a single-cross variety of high starch maize. The ear of the hybrid is cylindrical, 23 cm in length, 14-16 in ear rows. The kernels are orange yellow color, with 75.08% crude starch. The weight of a hundred kernels was 40 g. The growing period from seedling emergence to maturity was 125 days. The hybrid is resistant to diseases and lodging. It suits to be planted in the eastern mountain region of Liaoning province, the medium mature area of Jilin province and the first accumulated temperature belt of Heilongjiang province and Inner-mongolia.
