Linear regression model is useful to evaluate the adaptation of a quantitative character to the change of environments. However, the stability in the regression model is a relative measure depending on the genotypes and environments included in the test. Therefore, the regression model for G×E interaction is a descriptive model based on the data being analysed, but not a predictive model. This results in positive correlations between the phenotypic mean and regression coefficient. The correlations to occur is that all regression lines for all genotypes pass throught a common point, that is the regression should be concurrent. The concurrent point can be used to predict the performance of untried genotype when grown in a hypothetical environment, if both genotype and environment are considered as random samples from larger populations. Moreover, the stability of a quantitative character of a plant often varies with time at different stage of growth and development. This results in the diversity of concurrence for different periods. Thus, this project is to study the tendency of concurrence with growth time, and establish a forecasting model in plant stability by inducing the close relationship between concurrence and growth time into the linear model. The experiments will be conduced to test reliability and applicability of the above-mentioned empirical model by using Arabidopsis thaliana plants as materials.
