Quantification of nematode numbers in population parents and SSD lines. The root dry weight (open bars not inoculated, closed bars inoculated) of Herald, RH-1 and six SSD lines of the Herald x RH-1 cross varying in root damage score (RDS) was measured. The number of P. neglectus nematodes was quantified using nematode-specific PCR on roots (open circles). Bars indicate standard errors of four repeats for each plant line.
