| 摘 要： | 应用非参数统计量对2002年河南省玉米杂交种区域试验4000株／667m^2密度(一)组的资料进行了度量。结果表明：在供试杂交种中，滑986、洛试202以及浚9925产量较高，分别位于第1、2、3位，高于或显著高于其他品种，各参试杂交种产量稳定性(或适应性)指数间有差异，但没有达到显著水平。对品种差异分辨力较高的试点为驻马店市农科所、睢县农科所以及浚县农科所。

| Abstract: | Nonparametric statistics method is used to measure the regional testing data of group 1 corn hybrid strains of Henan Province, the density of which is 4000/667m~2. Results show that out of the corn hybrid strains being tested, yields of Hua 986, Luo 202 and Xun 9925 rank No. 1, 2 and 3 respectively, higher or significantly higher than other strains. Yield stability index between corn hybrid strains are somewhat different but not very much. Zhumadian, Sui Country and Xun Country Institute of Agricultural Science are testing locations which have high identifying ability for the difference of strains. |
