| 摘 要： | 本文用Tai模式和方法分析了南充地区1987年区域试验中六个花生品种的丰产性和稳产性。结果表明,各参试品种的两种产量稳定性参数值均有较大差异,反映了各品种在本地区夏播条件下有不同的遗传稳产性和适应性。产量与两种稳定性参数之间没有显著相关。有的品种表现高产、稳产和适应性广而且稳产性好的品种产量构成因素一般也表现稳定。通过分析比较,认为这种分析方法是研究品种的稳产性和适应性较好的方法。

| Abstract: | The productivities and yield stabilities of six peanut varieties tested at seven sites in the 1987's peanut regional test in Nanchong of Sichuan Province were analysed by the Tai G.C.C.model.The results of this study showed that these varieties differed considerably in parameter values of both yield stability and adaptability in this regional test of summer sowing peanut. There was no significant correlation between the yield and stability paramen-ters.One variety showed high and stable yield and wide adaptation.And a cultivar with better yield stability had generally stable yield components.The analysis method used in this study might be better than other methods for breeders to use in estimating peanut varietal stability and adaptability exactly and comprehensively over a range of enviromments.It could be used as on additional criterion to evaluate new varieties. |
