The objective of this study was quantify the influence of some environmental variables on genotype by environment interaction (G x E) in melon. It was utilized yield data of eight hybrids of cantaloupe melon evaluated in nine environments in the state of Rio Grande do Norte, Brazil. Aiming to identify environmental variables related with G x E interaction and quantify genotypic sensibility of hybrids were estimated factorial regression models and Spearman correlation coefficient between scores of principal components of AMMI analysis and the environment variable averages. The medium temperature, maximum temperature and minimum temperature were the variables that most influence on G x E interaction in melon to yield.
