More than 64% of maize in China is used as animal feed, 8% is used for industrial materials, and the rest is used for human consumption. The increase of maize yield relied on the development and utilization of hybrids in the past four decades. It was estimated that 40% of the yield gains can be attributed to the utilization of maize hybrids in China. All the commercial hybrids in China were developed by Chinese breeders domestically. Line recycling and selection is the most utilized method for maize breeding in China. Breeders also pay more attention to using population as breeding resources. The germplasm for hybrid maize breeding program in China consists of two resources, local and exotic. According to pedigree data, the germplasm in China may be divided into five groups: Tangsipingtou group (18.2%), Luda Red Cob group (17.9%), Lancaster group (32.8%), Reid Yellow Dent group (17.4%) and new groups (13.7%). It is noted that the combination of Chinese germplasm with US germplasm is usually a excellent pattern. To meet the demand for food security in the future, maize yields should reach to 8 tons per hectare, and yield potential should increase at an annual rate of 100 kg per hectare. In order to achieve these goals, the priority areas for maize breeding in the future include: Conservation and utilization of genetic resources, modification of elite lines, population improvement and germplasm enhancement, as well as improvement for tolerance to biotic and abiotic stresses. In order to raise the efforts in maize breeding research, scientists in China must communicate with other scientists of the world. The cooperation between China and CIMMYT is very important for maize research and sustainable production in this country , which will not only benefit China, but also the world.Collection: CIMMYT Publications Collection
