Pratylenchus neglectus resistance of rust-resistant and rust-susceptible Excalibur/Kukri doubled haploid lines. Classification of lines as carrying or not carrying Lr20/Sr15 rust resistance was based upon disease responses observed after inoculation of seedlings with appropriate pathotypes of Puccinia triticina and Puccinia graminis f. sp. tritici. Evaluation of resistance against the root lesion nematode Pratylenchus neglectus was based upon estimation of the quantity of P. neglectus DNA in the roots of inoculated wheat plants. The box spans the interquartile range of the estimated quantity of P. neglectus DNA per plant, the horizontal line within each box indicates the median. The whiskers extend to show the spread of data within the ‘inner fence’ (1.5 times the interquartile range beyond the quartiles). The solid black dots represent outliers within the ‘outer fence’ (3 times the interquartile range beyond the quartiles). The white dot represents an outlier outside of the ‘outer fence’.
