Corn Hybrids Adapted to Climate Change in Northeast China.

Planting improved hybrids has been one of the most effective methods to offset the negative effects on the growth and grain yield by climate change. In this study, 9 dominate maize hybrids which mainly planted in Northeast China (NEC) during the past four decades were replanted in 2010 and 2011, actual yield contributions of hybrid improvements were estimated and evaluated through crop modeling and statistical analysis. To further explore the hybrid improvements, the radiation-use efficiency of each hybrid was also evaluated. We will present our experimental findings, simulation results, and climate change perspectives to corn hybrids in NEC.
