对晋单30号玉米新杂交种的高产潜力、稳产特性及抗逆抗病性采用主效应值、变异系数、标准差比数、回归系数及高稳系数等多种方法进行分析。结果表明：晋单30号产量潜力大，稳产性佳，对不良环境有较强的抵抗力和忍耐力，在一般环境和特殊环境中均表现出较高的生产力和良好的种植效益，特别在有利环境中栽培更易获得高产。
The high yield potential, stable yield characteristics and resistance to disease resistance of new maize hybrids of Jindan No. 30 were analyzed by the methods of main effect, coefficient of variation, standard deviation ratio, regression coefficient and high stability coefficient. The results showed that the yield potential of Jindan 30 was high and its yield was stable. It had strong resistance and endurance to adverse environment, and showed high productivity and good plantation benefits in general environment and special environment, especially in Cultivation in a favorable environment makes it easier to obtain high yields.
