Abstract: Abstract: In this paper, according to the results of spring sowing special early mature maize regional tests in Shanxi province during 2008- 2009, special early mature maize hybrid “Changdan 525” was analyzed. A lot of analysis methods were adopted including the main effect amount, coefficient of variability,reliability of standard deviation, regression coefficient, high and stable coefficient and so on. The results showed that it's a good maize hybrid and had large crop potentiality, high and steady production and wide adaptation.It was adapted to be widely sowed in spring maize early mature regions in Shanxi province ,Taihang and Taiyue regions ,summer sowing regions and other corresponding ecological regions.
