Evaluation of pepper genotypes for green pod purpose was carried out at Melkassa, Wonji and Fogera in 2018, 2019 and 2020 with the objective of identifying genotype by environment interaction and select elite lines of pepper from the genotypes. The data was subjected to analysis of variance, and means were obtained to perform the GGE-Biplot analysis. The graphic results showed variation in the performance of the genotypes in the locations evaluated. The performance of the genotypes AVPP0512 and AVPP9905 was identified as ideal, with maximum yield and good stability in the test environments. On the other hand, among the three test environments Melkassa is both the most representative and discriminating environment, enabled to select the best adapted genotypes. Fogera and Wonji were the least representatives. Wonji showed good in discriminating whereas Fogera was poor. There mega-environments were formed and genotypes AVPP0512, AVPP9905 and AVPP0411 had the best performance within Melkassa, Fogera and Wonji environments respectively.
