Abstract: In order to better develop maize production in Shanxi, the author divided the whole province area into different planting areas according to the complex topography and changeful climate. The author studied the correlations between growth period, plant height, ear height, ear length, ear thickness, bald tip length, rows of each ear, grain number per row, hundred-grain weight, rate of seed and yield of varieties which had yield growth or the yield growth listed as top 5 in each testing area. The results showed that the correlations between the characteristics and yield were not the same in the different areas. It could effectively improve the utilization of agricultural resources and raise the yield per unit area to breed different varieties according to different requirements of corn characteristics in different ecological areas.
