In this experiment, with the single factor random block design, selected seven middle-late mature maize hybrid varieties which were planted, the paper compared growth stage, growth traits, theoretical yield and actual output of different varieties, analyzed the yield performance of different varieties in Yuxian. The experiment provided the promotion basis about what variety is more appropriate in this ecological region. The result indicated that Woyu 963 had faster growth, faster late dehydration and high productivity. The detailed advantages included the faster growth of visible and expanding leaves, high plant height, matured plants with green leaves at late stage,the extended duration of leaf function, increased the quality of the grain and good productivity. So Woyu 963 maize hybrid is a good variety that is proper to be planted in middle-late mature ecological region in Taihan mountains.
