MARQUEZ-VASALLO, Yarisyen; SALOMON-DIAZ, Jorge Luis  e  ACOSTA-ROCA, Rosa. Analysis of the genotype environment interaction in the potato crop (Solanum tuberosum L.). cultrop [online]. 2020, vol.41, n.1, e10.  Epub 01-Mar-2020. ISSN 0258-5936.

The study of the genotype environment interaction is one of the determining factors in the selection and recommendation of cultivars, which allows to increase the efficiency of the genetic improvement. With the aim of highlighting the importance of the analysis of the genotype environment interaction in the last stage of genetic improvement in potato cultivation, this bibliographic review was carried out, where essential aspects of the crop are collected, such as its taxonomic classification, main characteristics morphological and genetic, as well as elements to take into account for the genetic improvement and analysis of the genotype environment interaction in this crop. It is concluded that knowing the magnitude of the interaction genotype environment for a cultivar in specific environments previously, allows identifying more stable genotypes or with better specific adaptation when making the selection and recommendation of the cultivar in the final stage of genetic improvement.

Palavras-chave : genetic improvement; adaptation; stability; selection.
