摘要

共點模式在各試因均爲逢機樣本之前提下，可對同一族羣其他未受試基因型在未受試環境下的反應表現進行預測。該模式係以共點之觀念引入評價適應性的迴歸模式中，而將交感成分同時隨基因型效應及環境效應作迴歸分析。其共點介量的預測效果與生物學上之解釋，在本文中均予詳加探討。
最後，並配之以Arabidopsis thaliana植物鮮重資料作爲實例分析，以說明共點模式在基因型與環境交感效應之研究上的應用價值

並列摘要

Concurrent model can be used to predict the performance of an untried genotype when grown in a hypothetical environment if both genotype and environment are considered as random samples from larger populations. This involves a development of the regression analysis used in assessment of adaptation, and allows for the regression of interaction components onto both genotypic and environmental effects. The usefulness of the single joint regression for prediction is outlined, and the biological interpretation of concurrent is given.
The applicability of the emprical models to the data on plant fresh weight of Arabidopsis thaliana is illustrated by means of example.
