同异分析法在山东小麦新品种(系)综合评价中的应用

Application of Identical and Different Analysis Method in Comprehensive Evaluation of Shandong New Wheat Cultivars(Lines)

采用同异分析法,对山东省区试8个小麦新品种(系)的13个主要性状指标进行了综合分析和评价。结果表明,烟2415、山农D642、10-7的联系度值较高,排在前3位,与田间实际观察结果基本吻合。同异分析方法是对新品种(系)进行评价分析的一种新方法,该方法和常用的方差分析相比,运算简便,易于掌握,评价更全面、更合理,用于评价小麦新品种(系)切实可行。

With the identical and different analysis method, 13 main traits of 8 new wheat varieties （lines） from Shandong wheat variety regional test were comprehensively analyzed and evaluated. The results showed that Yan 2415, Shannong D642 and 10 -7 were of high connection degree, and ranked in the top three, consistent with the actual field observation results. The identical and different analysis method was a new approach for evaluation and analysis of new varieties （lines）. Compared to the common variance analysis, the method was simple for calculation, easy to master, and more comprehensive and reasonable for evaluation, therefore it was feasible for evaluation of new wheat varieties （lines）.
