The new maize variety test was conducted to select fine varieties suitable for the ecological environment in Chuxiong Prefecture and speed up the variety upgrading. The results showed that Yunrui 392,Yunrui 407 and Yunrui 7 had good comprehensive traits,great lodging resistance,stable yield and good disease resistance,and their yield was 9531. 3,9312. 5 and 9250. 0 kg/ha,respectively,close to the yield of control variety Beiyu 16,indicating that the yield potential was large and they could be planted in Chuxiong to replace the varieties with low yield and poor resistance.
