The population of the tobacco cyst nematode Globodera tabacum was examined for the ability to reproduce on several rootstocks for eggplant. Although G. tabacum produced many cysts on Solanum integrifolium rootstock cultivar Akanasu, no cysts were produced on S. torvum rootstock cultivars Tonashimu and Torero. We then examined the suppressive effect of S. torvum cultivar Torvum vigor and tomato rootstock cultivar Doctor-K on the population density of the nematode in soil. Torvum vigor and Doctor-K were resistant to G. tabacum. Nematode egg and second-stage juvenile densities in soil were reduced after cultivation with those rootstocks.
