摘要 最近开发的回归技术表明，基因型-环境相互作用引起的一些问题可以得到解决。因此，这些技术已应用于一项广泛试验的数据，该试验涉及在英国多个地点以不同处理方式种植的多年生黑麦草（Lolium perenne）品种。分析表明，品种的相对表现主要取决于它们是否种植为间隔植物或草丛。尽管基因型与环境的相互作用很大，但它们的大部分影响可以减少到基本上线性的范围。这些结果是根据相关品种的已知特征来考虑的，同时还讨论了更广泛的影响。
SUMMARY Recently developed regressional techniques suggest that some of the problems posed by genotype-environment interactions may be solved. These techniques have been applied, therefore, to data from an extensive trial involving perennial ryegrass (Lolium perenne) varieties grown under various treatments at several locations throughout Great Britain. Analysis reveals that the relative performance of the varieties depends mainly upon whether they are grown as spaced plants or swards. Even though the genotype-environment interactions are large, much of their effects could be reduced to an essentially linear scale. These results are considered in the light of the known characteristics of the varieties concerned, whilst the wider implications are also discussed.
