This study aimed to develop special paths for genetic-environmental interference and classify them based on their economic yield. As for genetic composition, the appropriate environment is the basic condition in developing superior cultivars through breeding programs. Genetic variation helps in distinguishing genetic compositions under different environments and maintaining their economic yield for long and short terms. Flexible genetic variation enables the genotypes to adapt to the changing environment and develop genes for resistance to various stress factors while stabilizing their production. Based on this, the classification of environments depended on their productive capacity into ideal, very suitable, suitable, and weak, depending upon the crop goals. Therefore, this study aimed to determine the percentage of genotypes’ contribution to ideal, appropriate, and specialized environments and their patterns of environmental distribution. The genetic-environmental interactions also reached either a positive or negative interpretation, depending on the genotypes’ response to the existing environment, as per plastic models and diagrams that facilitate the classification process.
