国际水稻遗传评价网（INGE）的1994年杂交水稻圃（IRHON）采用增广设计，包括了6个国家的17个地点和89个品种。为充分了解这类多点试验中关于品种和地点的交互作用，用加性主效应和乘积交互作用（AMMI）模型，以若干项乘积之和估算品种和地点的交互作用。借助双标图，可鉴别对地点有特殊适应性的品种。如果有参试地点的环境l因子的数据，AMMI模型还可帮助我们用环境因子解释品种和地点的交互作用。通过本文对1994年杂交水稻圃数据的分析，我们看到AMMI模型是分析多点试验数据的非常n效的工具，能为育种项目和决策部门提供非常有价值的品种适应信息。 The International Rice Genetic Evaluation Network (INGE) 1994 Hybrid Rice Paddock (IRHON) is an augmented design that includes 17 locations and 89 varieties in 6 countries. In order to fully understand the interactions of species and loci in such multipoint experiments, the interaction between breeds and loci is estimated as the sum of several products using additive main effects and product interaction (AMMI) models. With double plot, you can identify the species with special adaptability to the site. The AMMI model also helps us to explain the interaction between breed and locality using environmental factors if there are environmental l-factor data at the test site. Through the analysis of the 1994 hybrid paddy field data, we see that the AMMI model is a very n-efficient tool for analyzing multi-point data and provides valuable breeding program and decision-making information on species adaptation.
