There are several reasons for diversification in the use of rootstocks in the state of Paraná, as the search for induction better fruit quality, resistance to biotic and abiotic stresses, and others. The low diversification of rootstocks in Paraná citrus make it vulnerable to the occurrence of diseases. The main rootstock used in Paraná is the Rangpur lime, which is susceptible to the decline of citrus, sudden death and gummosis. The adoption of new rootstocks, such as hybrid trifoliate with grapefruits or tangerines, which have good resistance to disease and good quality fruit induction can make more sustainable citrus production in the medium and long term. Other important features demanded by the citrus sector refer to short plants with high production efficiency, producing fruit with high content of soluble solids, thin skin, good post-harvest conservation and production at different times. In the American state of Florida, in São Paulo, and in other parts of the world, and citrumelos citrandarins have been tested and generally showed characteristics of interest to the productive sector. Therefore, Knowledge of rootstock genotypes, based on previous experience is of great importance for the planning of diversification and maintaining
the sustainability of Paraná citrus industry.
