Abstract: In this paper, thirteen maize hybrids were applied to elucidate the yield performance and the correlation between yield and yield characteristics based on the six economical traits (i.e. ear length, ear row number, bare tip length, net weight per ear, KWEI and yield) of maize. The results showed that ear row number and net weight per ear were significantly and positively correlated with yield. To enhance ear row number and net weight per ear, reduce bare tip length and give dual attention to other agronomic traits was an effective way to enhance the maize yield.
