玉米新品种在秦巴高海拔山区的适应性分析

Adaptability analysis of new maize varieties in high elevation mountain of Qinba

用产量增产百分数、差异显著性、变异系数法、回归系数法、高稳系数法和非参数度量法等多种分析方法 ,对 10个玉米新品种在高海拔山区 4个地点的适应性进行了系统聚类。结果表明 ,农大 10 8、农大 3138、陕资1号、成单 18号、97Q- 16 7和中单 32 1等 6个品种在高海拔山区表现出较高的生产潜力和较强的稳定性 。

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.
