Abstract: For the aim of 100 billion pounds grain output in China, the application of elite maize varieties, which was the first major grain crops in China, was a key way to improve the per unit area yield and the total production in maize. Based on the rich genetic resources, the elite hybrid was selected through the integration of "high standard, large population and severe selection", IPT, DH and other breeding techniques. The elite variety‘Jingnongke728’,‘Jing MC01’and‘Jing 2416’as the female and male parent respectively, which had been authorized by National Crop Variety Committee (No.2012003) and Beijing Crop Variety Committee (No.2014006). The elite hybrid showed better lodging resistance, high density tolerance, high yield better yield stability, high dehydrate rate, early maturity. The performance of suitable for mechanical harvesting had been verified in many places such as Beijing, Tianjin, Tangshan, Langfang, Baoding and Cangzhou in China. The hybrid seeds production technology was easily and higher yield to get, so reducing the cost of production. It would be also convinced that the combination of elite hybrid and scientific managements will increase the per unit area yield and the total production in maize, and which will lay the foundation for the food security in China.
