A segregating population obtained by crossing Chardonnay and Tocai friulano, two varieties with very different susceptibility to “flavescence doree” (FD), was studied to dissect the genetic basis of FD resistance. The visual observations in the vineyard of FD-infected F1 individuals allowed to verify the segregation of the characters and to evaluate and measure traits associated with the low or high susceptibility to the disease. Furthermore, genotyping by sequencing was used to genotype the F1 offspring and a linkage map was subsequently constructed.
