AMMI analysis for grain yield stability of pearl millet (Pennisetum g/aucum L.) genotypes

Abstract

Improvement in grain yield of pearl millet is one of the focal endeavors of pearl millet (Pennisetum glaucum L.) breeding. As pearl millet is grown in tropical and subtropical agro-ecologies, it is important to asses adaptation and yield stability of promising genotypes across environments. Various methodologies have been explored to study genotype x environment (G x E) interaction and to predict the phenotypic response to changes in the environment [1 ]. The success of identifying high yielding genotypes from yield trials depends on the effectiveness of the statistical analysis used to evaluate parents in data and estimated yields [2].
