There is a need for identifying the specific environments for the selection of adapted and stable genotypes for quality traits in chilli pepper. Among these quality traits, pungency and coloring matter are the most important ones, which need to be in stable amounts in final products. Hence, this multi-environmental evaluation of chilli pepper genotypes was done in three distinct environments, to identify the suitable environments for selection and also suitable genotypes for specific quality traits. The study includes 43 chilli genotypes tested for three distinct growing conditions for nine different quality traits at Punjab Agricultural University and data was analyzed using Eberhart & Russell?s model and GGE Biplot analysis. The environmental effect accounts for more than 35% variation for the capsaicin in oleoresin and dry matter content. While the traits namely capsaicin content in red powder (3%) and capsaicin in green chili (4.73%) were least influenced by the environment. The contribution of G?E interactions was ? 25% for all the studied traits except ascorbic acid. The genotype AC 101 was best for capsaicin content in green and red chilli powder across the environments. The data generated from this study help to identify the stable and superior genotypes for quality traits in early, main and late-season planting.
