Relative performance of some root-knot nematode resistant tomato lines derived from intervarietal crosses

Five root-knot nematode resistant tomato breeding lines derived from five different crosses through pedigree method were evaluated in replicated yield trial for four years. The highest prforming line 1-6-1-4 was also tested in multilocation trials. This line gave an average yield of 574 Q/ha which is 40% higher than the checks and has determinate plant habit, bearing medium sized pear shaped fruits. It exhibited resistance to root-knot nematodes at all the sixteen centres where it was tested.
