For these purposes, 98 inbred lines of yellowmelon and two commercial controls, Vereda and AF-646, were evaluated in a randomized block designwith two replications, at the conditions present in Mossoró and Baraúna. Analyses of the following traitswere performed: fruit yield, mean fruit weight, pulp thickness, pulp firmness and soluble solids content. Acomplex portion of the GxE interaction was predominantly detected for all traits. The recommendation inthis case is to promote selection in each environment. Alternatively, selection based on the average behaviorof the inbred lines is the strategy that generates the greatest gains, approaching those obtained throughdirect selection in each specific environment. The selection indexes aimed at reducing the expression of alltraits proved to be best for both locations. The index constructed for Baraúna allowed the selection of agreater number of inbred lines with a higher yield potential and better quality fruit and, thus, greaterefficiency. 2016 artículo científico 1679-9275 https://www.redalyc.org/articulo.oa?id=303044042006 https://www.redalyc.org/journal/3030/303044042006/ https://www.redalyc.org/journal/3030/303044042006/html/ https://www.redalyc.org/journal/3030/303044042006/303044042006.epub https://www.redalyc.org/journal/3030/303044042006/movil en http://www.redalyc.org/revista.oa?id=3030 Acta Scientiarum.
