采用等权、加权关联度和产量3种方法，分别分析我省淮北片连续10a小麦区试资料，获得对参试种的3种评价结果。经与参试种实际使用情况相比较，发现上述3种评价结果均不够准确。进而指出其原因在于上述方法缺乏判别参试种优劣的标准。为此将对照引入这3种方法中作为判别标准，确定参试种的化与劣，结果表明，按照加权关联度法分析，其2a排序结果均优于对照的参试种，绝大多数得到推广使用，因而这一改进后的新方法是可靠的，比另2种方法及常规方法更加准确，值得重视。
Using the methods of equal weight, weighted incidence and yield, we analyzed the regional trial data of Huaibei slice continuous 10a wheat in our province for three kinds of evaluation results. Compared with the actual use of test species, we found that the above three kinds of evaluation results are not accurate enough. Furthermore, it is pointed out that the reason for this is that the above method lacks a standard for judging the pros and cons of the test species. To this end, we will control the introduction of these three methods as a criterion to determine the variety and inferior test varieties, the results show that, according to the weighted correlation analysis, the results of its 2a are better than the control of the test species, the vast majority of access Therefore, the new improved method is reliable and more accurate than the other two methods and conventional methods, which deserves attention.
