【Abstract】 Zhongyuandan No.32 was developed through hybridization of two inbred lines Qi 318 and Yuanfuhuang.It has high yield in the soil with medium moisture and fertility, it yields 7500～12000kg of seed and 52500～105000kg of fresh straw per hm\+2. It is rich in nutrition in both seed and straw with coarse protein conent of 12\^77% and 9\^2% respectively, so it is a both food\|forage maize variety. It also has higher resistances to diseases and stresses, and suitable to be grown in Huanghuai region of south China and Ningxia, Inner Mongolia, Gansu, Xinjiang of north\|west China. Zhongyuandan No.32 has higher efficiencies of photosynthesis and absorption of nitrogen, which are its physiological and biochemical bases of leading to high yield and good quality.更多还原
