Abstract: The purpose was to breed high yield, and drought, lodging and disease resistant new maize varieties. The traditional breeding methods and molecular techniques were combined, and the excellent American maize germplasm was used,‘Jindan 77’was bred with L3115 (female) and L0367 (male) in Modern Agriculture Research Centre of Shanxi Academy of Agriculture Science. The variety passed the assessment of Shanxi Crops Variety Examination Committee in 2010.‘Jindan 77’had high yield, good grain quality, multi-resistance, and resistance to high density. Its starch content was 74.45%, and the average yield was 11400 kg/hm2. The hybrid seeds production technology was easy, and the yield was high, so the cost of production was reduced. The combination of production and scientific management could increase the yield per unit area and the total production of maize, thus to play a significant role in ensuring the food security in China. The application prospect of‘Jindan 77’is promising.
