ABSTRACT

The study was carried out to identify resistant rootstocks of Solanum species for grafting of cultivated eggplant varieties against root-knot nematode and to evaluate the grafting compatibility of eggplant varieties with wild Solanum root-stocks. Three experiments were conducted in this respect. Six wild Solanum root-stocks were screened against root-knot nematode (Meloidogyne incognita). The root-stocks Solanum torvum and Solanum sisymbriifolium showed resistant reaction against root knot nematode. Fourteen varieties/genotypes were screened against root-knot nematode among which six varieties/genotypes showed resistant reaction. Three cultivated eggplant varieties viz., Sufala, Singnath and Kazla were grafted on Solanum torvum and Solanum sisymbriifolium. The highest grafting success was 95% in case of Solanum torvum with Sufala and the lowest (85%) in Solanum sisymbriifolium with Singnath. The success of grafting was not affected significantly due to the effect of scion and or of root stocks. The grafted plants showed resistant reaction against the disease while the scion plants showed susceptibility in the sick beds. The grafted plants also showed resistant reaction against the disease in the field conditions. The grafted plants also outyielded compared to the scion plants. The grafting combination Solanum torvum with Sufala gave the highest yield compared to other grafting combinations and non-grafted plants.
