Genomic localization of QTL associated with resistance to root-galling (RG) by: A, avirulent M. incognita and B, aggressive M. javanica. The QTL were detected in the CB46-Null x FN-2-9-04 F${}_{2:3}$ population phenotyped for RG under field infestation. Horizontal dashed line represents the Bonferroni threshold of significance at P < 0.05 [-log(p) = 4.8]. Old LG represents former cowpea linkage group numbering and Vu indicates the new cowpea linkage group numbering based on the cowpea pseudomolecules (Lonardi et al. 2017).
