Özet

Root-knot nematodes (RKN) cause yield losses in eggplantgrowing areas. There are no known varieties of eggplant (Solanum melongena L.) that are resistant to RKNs. However, the wild relative of eggplant, S. torvum (Sw.), provides resistance to some RKN species and is used as a rootstock for cultivated eggplants. Therefore, determination of the reproductive capacity of nematodes on eggplant rootstocks developed from S. torvum is required for effective management of RKNs that are widely present in vegetable growing areas. In the present study, the degree of reproduction of Mi-1.2-virulent and avirulent isolates of M. incognita, M. javanica, and M. luci on eggplant rootstocks, Hawk and Bogac, was evaluated in a plant growth chamber. Hawk and Bogac were resistant (< 10 egg masses per whole root system) to all avirulent and virulent isolates of M. incognita, M. javanica, and M. luci. This study is the first report on the resistance of S. torvum to virulent isolates of M. luci. Results indicate that S. torvum offers broad-spectrum resistance against RKNs.
