Abstract: Citrus plants are part of one of the most important fruit crops in the world in subtropicais countries. It is one of the most popular sources of tasty fruits that provide multifunctional bioactive compounds such as folic acid, fiber, vitamins and essential oils. The use of rootstock is important in citriculture to ensure a more uniform production and maintain the genetic characteristics of superior cultivars, adding agronomic value. However, the compatibility between the scion and the rootstock is necessary for the success of its cultivation. The rootstock influences the phenotype of the plants, their productivity, size and precocity, as well as the quality of their fruits and their resistance to abiotic and biotic stresses. Therefore, one way to overcome the problems caused by Phytophthora diseases would be the use of scion/rootstock combinations tolerant to the pathogen. In this sense, the objective of this study was to evaluate the correlation between phenotypic attributes of plants with 'Pera' orange [Citrus × sinensis (L.) Osbeck] and 'Tahiti' acid lime [C. × Tanaka latifolia (Yu.) Tanaka] grafted onto 'Indio' citrandarin ('Sunki' × 'English' trifoliata) rootstock inoculated with Phytophthora citrophthora. The study of correlation between phenotypic attributes contributes to plant breeding programs, in the selection of scion/rootstock combinations with desirable traits. The experiment was carried out in a greenhouse at Embrapa Mandioca e Fruticultura, in the municipality of Cruz das Almas, BA. The experimental design was completely randomized (DIC) with nine replications. The correlated characters were plant height (cm), diameter of the rootstock stem (mm), number of leaves and size of the lesion caused by P. citrophthora (mm2). The plants were inoculated with a disk of culture medium containing the mycelium of P. citrophthora, taken from colonies cultivated on eight-day-old carrot-agar medium, kept in a B.O.D greenhouse at 25 ºC and 24 h of light. The discs were placed under the rootstock stem bark, this area was protected for about 15 days with moistened cotton and covered with adhesive tape. Lesion size evaluations were performed 60 days after inoculation, measuring the percentage of injured area under the bark in pixels using the ASSESS program. The data obtained in the phenotypic evaluations were submitted to Pearson's correlation coefficient analysis at 5% probability of error, with significance at the 1% level by the t test, using the Rcmd package in the R software (R Core Team Development, 2024). The results showed significant correlation coefficients between most of the evaluated characters, with exception between the stem diameter and the number of leaves. Of the evaluated characters, the one that presented the highest positive correlation with lesion size was the character plant height (r=0.3782). The highest negative correlation value with lesion size was number of leaves (r= - 0.3802). Thus, it is inferred that these correlations indicated that taller plants with fewer leaves in the scion/rootstock combinations evaluated are associated with larger lesions caused by P. citrophthora.
