| Abstract: |
| Through increased production percent of yield,distinct difference,variance coefficient method,regression coefficient method,high stabilization coefficient method and non-parameter tolerance method etc,adaptability of ten new maize varieties are analyzed at four pot of high elevation mountain areas in this paper.The result showed that the six varieties had higher production potential and stronger stability and were provided with favorable adaptability,which are Nongda 108,Nongda 3138,Shaanzi No.1,Chengdan No.18,97Q-167 and Zhongdan 321. |
