摘　　要：运用秩次变量nij和n'ij,非参数统计量Pi、P'i、Si和Dj描述2002年国区东北春小麦早熟旱地组区试资料的基本特征。分析结果表明:赤94-5号为丰产性和稳定性最佳品种,沈免96085、铁90010、哲麦7号和丰强7号为丰产性和稳定性优良的品种。对品种差异有较高分辨力的试点有7个,分辨力最高的试点为L8,有69.1％的差数为显著。Two rank variates nij and n'ij for the i th variety in the j th environment, four nonparametric statistics, Pi , P'i, Si and Dj were introduced to describe the basic characteristics of wheat regional trial data of the Northeast early-maturing group in 2002. The results indicated that the best productivity variety was Chi94-5,the best stability variety was Chi94-5 too,Shenmian96085,Tie90010,Zhemai7, Fengqiang7 was the high productivity and stability variety. Seven sites were found with environment differentiation,L8was the highest with 69.1% difference significantly.
