在不设重复的产量试验中,由于参试材料通常都是采取顺序排列,和邻近的对照相比,试验结果无法进行差异显著性分析。采用“增广设计”可不设重复,可以通过校正试验结果的方法进行显著性分析。后者用于早代初级产量试验中,能比较客观地评定大量的新系。 In a non-duplicated yield test, the test results were not able to make any significant difference analysis because the test materials were usually in sequential order compared to the adjacent controls. The use of “augmented design” may not be repeated, you can calibrate the test results for the significance of the analysis. The latter is used in the early primary production test, can objectively assess a large number of new lines.
