Genotype x environment interactions refer to the phenomenon where the performance or expression of a plant's traits is influenced by the specific environmental conditions in which it is grown. This interaction is crucial in plant breeding as different genotypes may exhibit different responses to various environmental factors such as temperature, soil type, moisture availability, and disease pressure. Breeders need to evaluate and select plant varieties that perform consistently well across a range of environments to ensure broad adaptability and stability of the developed cultivars.
considering G x E interactions in plant breeding is crucial for developing cultivars with improved adaptability, stability, and performance across diverse environmental conditions. By understanding how genotypes interact with different environments, breeders can enhance the success rate of variety selection, tailor breeding efforts to specific environments, and deliver improved plant varieties that meet the diverse needs of farmers and consumers.
