BB = alleles from resistant parent, AB = heterozygous, AA = alleles from susceptible parent; Exp. = expected ratio; RG = root galling, EM = egg masses per root system; Vu = cowpea chromosome naming (Lonardi et al. 2017); Isolate = Nematode isolate; Avr = avirulent M. incognita Beltran, M.j = M. javanica; ^balso fit a 3:1 ratio.
