Linkage map (a) for a PBA HatTrick $\times$ Kyabra chickpea population and outlier statistics for the association of marker positions on the Ca4 (b) and Ca7 (c) chromosomes with log-transformed numbers of Pratylenchus thornei per kg of soil and roots, as evaluated in the F₆ generation in 2018 (dark symbols) and the F₇ generation in 2019 (white symbols). In panel a, the horizontal lines on the linkage groups represent positions at which genotyping-by-sequencing tag pairs were mapped and the scale bar on the left shows genetic distances in cM
