Number of Meloidogyne incognita development stages at 7, 14, and 21 d after inoculation in four Cucumis genotypes. Genotypes consisted of a resistant control, C. metuliferus (PI 482452); susceptible control, C. melo ‘Hales Best Jumbo’; and two accessions of C. melo var. texanus (Burleson Co. and MX 1230). Initial population density was 200 J2/100-cm³ soil. Different letters over bars indicates a significant difference at P ≤ 0.05 according to chi-square analysis applied in pairs of genotypes.
