Abstract
Root-knot nematodes have a very broad host range and causing significant crop losses in many plant species of economic importance. The objective of the study was to determine reactions of eggplant genotypes representing 38 number of species against root-knot nematodes. This study was conducted at Adana Biological Control Research Institute, in a climate controlled growth chamber in 2017. The reaction of genotypes was determined by the classical test method, infected with M. incognita 1000 jüveniles / plant of eggplant seedlings. The plants were evaluated according to the galling index of the infected roots 60 days after nematode inoculation. According to the 0-5 scale, the galling index in the roots was determined between 0-2 in resistant plants, and 3-5 in susceptible plants. Results showed that eight of the 38 eggplant genotypes were resistant. The variation for gallling index in susceptible genotypes is probably due to the genetic background of genotypes. The resistant genotypes can be used in developing root-knot nematode resistant commercial cultivars.
