摘要
品种区域试验就是比较参试品种在不同地区的产量高低,最后确定品种(系)有无推广价值和适宜的推广范围。本文以黑麦草品种的多年多点试验为例,介绍一种计算平均产量(X)和品种与环境互作的变异系数(C. V)的分析方法。此方法可对区域品种试验的丰产性和稳定性进行评价,是品种区域试验分析的极优方法。
Variety regional evaluation aimed at comparing the productions of forage grass varieties selected and grown in different regions, and then, the adapted cultivating regions and the extending value for tested Varieties were determined. In this paper, taking long-term and different regional evaluation of rye strains for instance, the analysis method on calculating the mean grass production (X) and the coefficient of variation(C.V) of interaction between the strains and the enviroments is recommended. By this method, the high production and the stablity on the varieties in regional evaluation can be carried out. So this method is optimized approach in carrying out analysis of variety regional evaluation.
