2002～2003年小麦冬水组黄淮区试资料的非参数统计分析

Nonparametric Statistics Analysis on the Data of 2002～2003 Winter Wheat in Huang-huai Regional Test

采用莫惠栋、曹桂英报告的非参数统计方法对2002～2003年黄淮南片小麦品种(系)冬水组区试资料进行分析。结果表明:(1)邯郸6172、郑表004、新乡9408淮麦20的丰产性表现优良,其Pi(%)和P′i(%)值分别为78.3%、71.9%、71.5%、66.5%和52.5%、48.9%、48.0%、48.4%。(2)参试品系的产量稳定性有极显著差异。百农9711的产量稳定性最好,其Si=2.265。内乡991、郑麦004、邯郸6172的产量稳定性较好,其Si值分别为:2.353、2.471、3.162。对照种豫麦49的产量稳定性较好,其Si=3.176。(3)17个试点分辨品种差异的能力大小顺序为:宿县=睢县>西北农业大学>岗埠>新马桥>淮海>宝鸡>周口>阜阳>淮阴>涡阳>秦丰农业>徐州>河南省农科院>新乡>濮阳>漯河。

The data of 2002～2003 winter wheat in south of Huang-huai regional test were studicd by means of nonparametric statistics analysis in the report of Mo Hui-dong and Cao Gui-ying.The result showed:(1) High-yicld strains have four,which are Han-dan 6172、Zheng-Mai 004、xin-xiang 9408 and Huai-Mai 20.Their Value of P_i(%) and P′_i(%) were respectively 78.3、719、71.5、66.5 and 52.5、48.9、48.0、48.4. (2) The stablc yield of the strain differed greatly in the test.Bai-nong 9711 has the most stability in yielcl and its S_i=2.265,Nei-xiang 991,Zheng-Mai 004 and Han-dan 6172 have more,whoseValue of Si were 2.353、2.471、 and 3.162.The stableyield of Yu-Mai 49(ck) was general and its Value of Si=3.176.(3)The yield resolving powser in strains of seventeen experimental zones are in order:Suxian=Suixian>Northwest univevsity of Agriaclture>Gangbu>Xinmaqiao>Huaihai>Baoji>Zhoukou>Fuyang>Huaiyin>WOyang>Qinfengnongye>xuzhou>Henan Academy of Agricultural Sciences>Xinxiang>Puyang>Luohe.
