Concurrent dynamic model in stability analysis

Abstract

oncurrent dynamic model can be used to predict the performance of an untried genotype grown in a hypothetical environment at any growth time, when all the genotypes, growth periods and environments are selected randomly from the breeding population and from the full spectrum of time and environments, respectively. This involves the development of regressions of interaction components onto both genotypic and time-space effects, when the positive correlation between regression coefficient and phenotypic mean exists. The data on fresh weight of twenty-four lines of Arabidopsis thaliana grown under twelve different environmental conditions in seven growth periods were used to demonstrate the proposed model and to test its applicability.
