Additive main effect and multiplicative interaction analysis revealed significant impact of environment (E), and consequently a significant GE interaction of tomato genotypes at major locations of Kashmir Division. The environment (E), genotype (G), and GEI significantly affect the plant yield/ha (p < 0.001). The environment explains approximately 47.5% of the total sum of squares due to treatments (G + E+GEI). Assuming the weight of 50:50 (i.e. having equal importance for plant yield and stability), Arka Meghali, NDF-9, VTG-93 had high values for WAAS and were the stable genotypes. The plot based on the MTSI shows the rankings of the genotypes as per the multi-trait stability index and indicates Arka Meghali and NDF-9 as the selected genotypes. The evaluation based on various stability indicators are in agreement with the results from the Multi Trait Stability Index. This study underscores the significance of understanding the complex interplay between genotype, environment, and their interaction on crop yield, providing valuable insights for tomato cultivar selection and agricultural practices in the ecologically important region of Northern Himalayas.
