【摘要】 1984～1986年进行2年7点的小麦多点品种比较试验。1986～1988年进行2年1点的多栽培处理环境的品种比较试验,采用4种方法,估计产量稳定性参数和品种适应性参数,根据统计结果,对4种参数估计法作了讨论。认为对环境资料,如何进行更好地统计分析还须作更多的探讨,标准差比数（a₁）作为产量稳定性参数,更为简便、直观。更多还原

【Abstract】 Seven wheat cultivars were evaluated for yield grown in a 3-replicated, randomized block layout at 7 sites in 1984～1986 and in a 3-replicated, split-split block layout at one site in multi-cultivated environments in 1986～1988. Four methods were used to estimate the stability and adaptability parameters. The question of how to analyse environmental data has not yet been properly addressed and more research is needed with an attempt to find a solution to this statistical problem. The standard deviation ratio（a₁） is more convenient and more audio-visual as a yield stability parameter.更多还原
