Eberhart, Russell

Eberhart and Russell developed a statistical method to evaluate plant varieties' performance across different environments. Their model assesses three key aspects: the overall average yield (mean performance), the consistency of a variety's yield (stability), and its ability to perform well in favorable conditions (responsiveness). This helps breeders identify varieties that not only yield well overall but also maintain reliable performance and adapt effectively to changing environments. Their approach is widely used in agricultural research to select cultivars that balance high productivity with stability across diverse growing conditions.
