作物品种试验中,新的品种挑选与推荐,经常是以异地鉴定与区域试验为前提。这是由于品种与环境存在互作,所以对品种与环境间互作的了解及稳定性的评定是十分必要的。本文的目的是评价品种与环境的互作作用,比较品种产量稳定性的差异,寻找对品种产量稳定性的评定有实际价值的测定方法。
In crop trials, new varieties are selected and recommended, often based on the identification and testing of different regions. This is due to the interaction of breeds and the environment, so it is necessary to assess the mutual understanding and stability of breeds and environments. The purpose of this paper is to evaluate the interaction between breeds and the environment, to compare the differences in the yield stability of the breeds and to find out the practical methods for the assessment of the yield stability of the breeds.
