Evaluation of P. pinaster response to pine wood nematode artificial inoculation in a 510-panel from five half-sib progenies

This dataset includes phenotypic data from an artificial pine wood nematode inoculation assay using a panel of 510 plants from five Pinus pinaster half-sib progenies (family 17, 77, 152, 440, and 465). The plants were maintained in 2,5 L pots in a greenhouse, placed according to a completely randomised experimental design organised in nine blocks. Symptoms after PWN inoculation were assessed weekly from the 14th dpi until the 447th dpi and were classified according to a visual scale: level 1 – 0 % of brown/wilting needles; level 2 – 1-25 % of brown/wilting needles; level 3 – 26-50 % of brown/wilting needles; level 4 – 51-75 % of brown/wilting needles; and level 5 – 76-100 % of brown/wilting needles. Symptom scores were combined into a single value for each plant, to quantitatively summarise the pine wilt disease progression over time and encompass a greater range of phenotypic variance compared to relying only on a single time-point measurement.
