品种同异比较分析法在小麦品种区域试验中的应用

Application of the Method of Variety Similaritydifference Comparative Analysis in the Wheat(Triticum aestivum L.) Varieties Regional Test

[目的]筛选最优的分析小麦（Triticum aestivum L．）区域试验数据的方法。[方法]根据品种同异比较原理与方法，对2003。2004年度安阳市农业科学院小麦区域试验数据进行分析。参试品种（系）8个，包括安02—43、安02—44、安02—45、安02—47、安02—49、安02—50、安02—52、豫麦18（CK）。[结果]安02-44、安02—45、安02—43综合表现较好。田间试验观察和综合分析认为，上述结论比较客观、可靠。[结论]应用品种同异比较分析方法分析作物区域试验数据可行且优越，具有良好的应用前景，建议在品种区域试验中推广应用。

[ Objective] The aim was to screen the optimal analysis methods of the wheat varieties regional test. [ Method] According to the principle and method of variety similarity - difference comparative analysis, the the wheat varieties regional test data of Anyang City Academy of Agricultural Sciences in 2003 - 2004 were analyzed. The trial varieties（lines） was eight, including An 02 - 43, An 02 - 44, An 02 - 45, An 02 -47, An 02 -49, An 02 - 50, An 02 - 52, Yumai 18 （ CK）, resp.. [ Result] The results showed that the comprehensive perform- ances of An 02 - 44, An 02 - 45 and An 02 - 43 were better. The conclusion above was more objective and reliable by the field experiment observation and comprehensive analysis. [ Conclusion] That applying the method of variety similarity - difference comparative analysis to analyze crop regional test data is feasible and superior, has a good application prospect, so it is recommended that this method should be popular- ized and applied in variety regional test.
