用Duncan、Finlay-Wikinson、Eberhart-Russell的方法和模式分析长江流域地区1980～1983年黄麻区域试验中9个品种的丰产性和稳定性。结果表明,参试品种间产量和稳定性参数都有相当大的差异和不同的适应性。为提高区域试验分析的准确性,应把Bartlett方差同质性检验列为联合方差分析的一个基本检验步骤。其联合方差分析的数学模型以选用混合模型即品种效应为固定模型,地点、年份效应为随机模型较为确切。用两种不同模式和方法估算品种稳定性,Eberhart较之Finlay的方法为佳,其定义和标准更符合生产实际。产量与稳定性参数回归系数b之间并无明显相关性。
Duncan, Finlay-Wikinson and Eberhart-Russell methods and models were used to analyze the high yield and stability of nine varieties in the jute region from 1980 to 1983 in the Yangtze River Basin. The results showed that the yield and stability parameters of the tested varieties all had quite big difference and different adaptability. To improve the accuracy of regional trial analysis, Bartlett’s test of homogeneity of variance should be included as a basic test of joint analysis of variance. The combined analysis of variance mathematical model to select the hybrid model that is the variety effect as a fixed model, location, year effect is more accurate for the random model. Using two different modes and methods to estimate the stability of varieties, Eberhart is better than Finlay’s method, and its definition and standards are more in line with the actual production. There is no significant correlation between yield and stability parameter regression coefficients b.
