摘　　要：采用高稳系数法(HSC)结合变异系数分析了2008-2009年度上海市区域试验中11个参试品种(系)的高产稳产性,结果表明:新品种浦优608、秋优169高稳系数和产量水平排序较高,变异系数也偏高,故在良好栽培环境下增产潜力大。新品种(系)S07-55、嘉07-34为丰产稳产型品种,地区适应性广;新品种青角574则属于低产不稳产类型,需要良好的栽培条件才可获得丰产。与几种常用统计参数间的相关分析表明,HSC法分析水稻新品种(系)高产稳产性简便有效,结合变异系数参数分析结果更加全面、准确。The high-yielding stabilities of 11 rice varieties（lines） tested in Shanghai regional experiment in 2008-2009 were studied by the high stability coefficient（HSC） method in combination with variation coefficient analysis.The results showed that the new varieties,Puyou 608 and Qiuyou 169,were high in the orders of both high stability coefficient and yield level but their variation coefficients were somewhat large,implying that they had a large potential of production under good cultivation conditions;The new varieties（lines）,S07-55 and Jia 07-34,had a high and stable yield and extensive regional adaptability;The new variety Qingjiao 574 was low in both yield and stability and needed good cultivation conditions to yield highly.The correlation analysis between commonly-used statistical parameters and the HSC showed that the HSC method was simple and effective in evaluating new rice variety＇s high-yielding stability and could be more complete and accurate in combination with the parametric analysis of variation coefficients.
