The present invention provides: a root-knot nematode resistance marker for tomato plants, exhibiting dominantly inherited root-knot nematode resistance; a novel root-knot nematode resistant tomato plant that includes a dominant root-knot nematode resistance locus and exhibits root-knot nematode resistance without depending on temperature conditions in a growing environment; a method for producing a root-knot nematode resistant tomato plant using the same; and a screening method for a root-knot nematode resistant tomato plant. The root-knot nematode resistant tomato plant according to the present invention includes a root-knot nematode resistance locus on chromosome 4. The root-knot nematode resistance locus can be identified using, for example, solcap_snp_sl_21346, solcap_snp_sl_21364, TK43, YU06, YK66, TY38, AR02, HT12, solcap_snp_sl_64250, solcap_snp_sl_21383, solcap_snp_sl 21385, and solcap_snp_sl_21390. By crossing the root-knot nematode resistant tomato plant of the present invention with another tomato plant, it is possible to obtain a progeny tomato plant having the root-knot nematode resistance.
