河南省夏玉米区域试验套种组承试点效应分析

Effect Analysis on Regional Test Sites of Summer Maize in Henan

根据河南省 1 2年来夏玉米套播组区域试验资料 ,对前后 1 7个承担该试验的试验点判别品种能力的强弱及产量结果年际间的稳定性、各试验点产量结果与汇总结果的吻合性进行了估算分析 ,并综合利用这 3项指标对各试点进行了归类。结果表明 :浚县、林州等 5个点是较理想的承试点 ,三门峡、郑州、商丘、平顶山等 4个点尚需进一步试验方能确定 ,其它

The ability to distinguish various varieties and yield stability and coincidence of 17 test sites are estimated based on the data of regional tests over latest 12 years in early maturing varieties in Henan province. The sites are classfied according to the three criteria above. The results show that five sites are ideal, eight sites aren′t ideal, four sites should be tested and analysed again.
