| 摘要: |
| 应用秩次变量nij和n′ij，非参数统计量Pi,P′i,Si和Dj描述了2001年国家绿豆品种区试资料的基本特征，并对参试品种进行综合评判。结果表明：绿豆区试品种间丰产性和稳定性存在显著差异，9239-8和9309-22是丰产性和稳定性较好的品种。20个试点中有14个试点对品种差异具有较高的分辨力，其中分辨力最高的试点为山西长治，发现80.0%的差数显著。 |

| Abstract: |
| Two rank variates nij and n′ij for the i th variety in j environment,and four nonparametric measures Pi,P′i,Si and Dj were introduced to describe the basic characteristics of mungbean regional trial data at whole nation in 2001.The results indicated that there were marked differences in productivity and stability between varieties.9239-8 and 9309-22 are excellent varieties in both productivity and stability.Environment differentiation was high at fourteen locations,Changzhi station in Shanxi was the highest and found out 80.0% difference significantly. |
