b> Mechanical damage, which reduces seed quality characteristics, refers to the physical injuries caused on seed during handling, harvesting, and conditioning. In maize (Zea mays L.) susceptibility to mechanical damage depends on genetic and environmental factors. The development of inbred lines with high seed quality and broad adaptability is essential in a breeding program. The objective of this study is to quantify the genotypic, environmental, and genotype-by-environment (GE) interaction effects on the mechanically damaged seed quality of experimental  maize inbred lines. Nine lines were tested in six environments defined by the location-seed-shape combinations. Each sample was artificially injured (damage treatment). Seed quality was measured by both the saturated cold test and fast green test. Statistical analyses were performed using AMMI model and results
