Jing2416, an elite maize inbred line, was developed by the Maize Research Center of Beijing Academy of Agricultural and Forestry Sciences. Based on the theories of "Pyramiding of Elite lines from the same Heterotic Group" and "High-density, Large-group, Strict-selection", Jing2416 was selected from the back-crossing population ((Jing24 × 5237) × Jing24). Jing2416 represents many merits, such as early maturity, fast dehydration, high tolerance to various diseases, drought and heat, high adaptability, high yield and general combining ability. By taking use of the elite breeding line Jing2416, twenty-one commercial hybrid varieties have been officially approved by national or provincial regional trials. Especially, the hybrid varieties of Jingnongke 728, NK718, MC121 and MC812 showed outstanding agronomical performance, and each of them has been planted over 67 thousands of hectares every year in China. The variety Jingnongke 728 has been accepted as the first mechanized harvesting varieties, as well as the control variety in mechanized-harvesting trials in Huanghuaihai region of China. Jing2416 as a founder inbred line has been used by several key projects and breeding platforms, such as national maize improved varieties, national maize industry technology system, national key research and development project of China, etc.
