摘　　要：农作物品种区域试验的结果能否从整体水平上客观真实地反映参试品种,与试验的质量和科学合理的评价方法密切相关。分析云南省2001-2002年玉米区域试验(南部组)的试验精确度,并运用灰色综合评判法对参试品种进行评价,结果表明云南省南部组区域试验的整体水平较高,试验误差控制得较好,数据可信。C608、改良892和靖99-69三个品种灰色评判为1级,与生产实际基本相符。Whether the result of regional trials of crop varieties can represent the actual characteristics of varieties involved is significantly relative to the quality of trials and reasonability of analysis methods of evaluation. After collecting all data of Yunnan southern regional trial of maize in 2001-2002, the experimental precision has been analyzed and all hybrids involved have been estimated by grey integrative evaluation. The result indicated that the error of trial was comparative small and the data from this trial were authendc, demonstrating the creditable quality of Yunnan southern regional trial of maize. That grey evaluation scores of hybrids C608, Gailiang892 and Jing 99-69 were 1 is corresponded to their actual performances in practical production.
