品种区试是育种工作的重要环节,其目的在于科学地评价每个参试品种的优劣,为新品种的合理利用提供依据。以往的区域试验多侧重于对参试品种的产量指标进行统计分析,而对其它性状只是按其调查数据直观地判断优劣。这样,对新品种的评价往往带有片面性。为此,本文介绍一种简单易行的方法—效用值决策法,旨在使之应用于区试结果的分析,以对新品种作出科学地评价。
The regional trial of varieties is an important part of breeding work. Its purpose is to scientifically evaluate the advantages and disadvantages of each tested varieties and provide the basis for the rational utilization of new varieties. In the past, the regional experiments mostly focused on the statistical analysis of the yield indicators of the tested varieties, while the other traits were directly judged by their survey data. In this way, the evaluation of new varieties often with one-sidedness. To this end, this article presents a simple method - the utility value decision-making method, which is intended to be applied to the analysis of the regional test results to make a scientific evaluation of new varieties.
