摘　　要：以变异系数(CV)、回归系数(b)、稳定性参数(ai)、高稳系数(HSC)为评价指标,对2013年广西省糯玉米区域试验(春季数据)的16个糯玉米品种进行高产稳产性分析。结果表明,参试品种的高稳系数(HSC)位次与增产位次大体相同,且与产量呈极显著正相关,同时与标准差(S)呈轻度负相关;其中,以庆甜糯2号、佳糯26、京科糯929的高产稳产性能较好。同时,结果还表明高稳系数法兼顾了稳定性参数的稳定性及平均产量的高产性,能较真实的反应品种的高产稳产性。In order to analyze the high stable coefficient of 16 varieties waxy corn, from the 2013 spring data of the regional trial in Guangxi, the index like variable coefficient （CV）, regression coefficient （b）, stability parameter （ai） and high stability coefficient were assessed in the experiment. The results showed that the test varieties locant of HSC kept up with the locant of increase yield, which with the yield was significant positive correlation, while with the standard deviation（S） was lightly negative correlation. Of which, the Yiqingtiannuo 2, Jianuo 26 and Jingkenuo 929 has better property of high-stable yield. Meanwhile , the HSC not only has the stability of stability parameter, but also has high average yield, therefore, it can really reflect the varieties stable high yield.
