摘　　要：运用秩次分析法对国家小麦区域试验数据进行高产性及高产稳定性分析。对各试验环境进行常规方差分析,并定义了3个统计数:平均分级值H1、产量秩次值H2和环境区分指数YM;在多重比较的基础上,对各参试品种产量稳定性进行了分析和评价。By using rank analysis method, high and stability yield analysis of data from national wheat variety regional trial was done, Firstly, the result of the test was dealt with by variance analysis way, and 3 statistical parameters were defined, which were grade numerals of average （H1）, rank numerals （H2） and circumstance differentiating index （YM） resp. Then based on the multiple comparison, the yield stabilities of various varieties were analyzed and appraised objeetivly. Key words
