摘　　要：以12个甜玉米品种区域试验产量数据为材料,采用常规的产量稳定性分析方法和高稳系数法对各甜玉米品种的高产稳产性进行了统计分析。结果表明:各参试品种的产量高稳系数与产量呈极显著的正相关,与产量变异系数呈极显著负相关;常规产量稳定性分析中的回归系数与产量相关性不明显,但与产量标准差和变异系数呈极显著负相关。研究表明,高稳系数可以作为甜玉米品种区域试验中高产稳产性的评价的指标。Used 12 sweet corn variety as material to Evaluate their high and stable yield performance of sweet corn variety in regional trial comprehensively by conventional method of stability analysis of the yield and HSC method. Results show that the coefficient of yield high stability and yield significantly positive correlation, and yield significantly negative correlation, The regression coefficients of conventional output stability analysis had no obviouse correlation to yield, but to suandard deviation and yield significant had negative correlation. Researched shows that the high stability coefficient can be as a index to evaluate high and stable yield performance of sweet corn variety in regional test.
