SANCHEZ ASPEYTIA, David et al. Estimation of the genotype-environment interaction in tomato (Solanum lycopersicum L.) with the AMMI model. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.4, pp.763-778. ISSN 2007-0934.

Tomato (Solanum lycopersicum L.) is a vegetable with high commercial value for fresh consumption and the manufacture of processed products. The potential of northern Mexico in the production of this vegetable is necessary to the formation of new genotypes of tomato and it is necessary to measure the genotype-environment (IG x A) interaction and determine the phenotypic stability of genotypes to the environmental fluctuations, the objectives of this work is focused to estimate the genotype-environment and stability of yield characteristics, physiological and quality of 25 tomato genotypes in three environments through the AMMI multivariate model interaction. Significant differences for quality variables (p< 0.01) in the IG x A were found AMMI The analysis result indicates that only two components explained 100% of the variation, with the experimental hybrid Q3 x R1 the best in terms the variables of quality and yield environments evaluation showed very different in their discrimination of genetic materials. Therefore it will be necessary to further assess these genotypes under different forms of production and environments so that the genes involved in the expression of the yield variables, physiological and quality go setting and the effect of the environment is minimized and so achieved genetic materials to suit different environments and high in nutritional compounds and food to enable this vegetable remain one of the most important national and global levels.
