Root-knot nematodes (RKN) cause yield losses in eggplant-growing areas. There are no known varieties of eggplant ( L.) that are resistant to RKNs. However, the wild relative of eggplant, (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 is required for effective management of RKNs that are widely present in vegetable growing areas. In the present study, the degree of reproduction of -virulent and avirulent isolates of . , . , and . on eggplant rootstocks, Hawk and Boğaç, was evaluated in a plant growth chamber. Hawk and Boğaç were resistant (< 10 egg masses per whole root system) to all avirulent and virulent isolates of . , . , and . This study is the first report on the resistance of to virulent isolates of . Results indicate that offers broad-spectrum resistance against RKNs.
根结线虫（RKN）在茄子种植区会导致产量损失。目前尚无已知的茄子品种对根结线虫具有抗性。然而，茄子的野生近缘种（Sw.）对某些根结线虫物种具有抗性，并被用作栽培茄子的砧木。因此，为了有效管理蔬菜种植区广泛存在的根结线虫，需要确定由该野生近缘种培育出的茄子砧木上线虫的繁殖能力。在本研究中，在植物生长室中评估了南方根结线虫（Meloidogyne incognita）、花生根结线虫（M. arenaria）和爪哇根结线虫（M. javanica）的致病型和非致病型分离株在茄子砧木Hawk和Boğaç上的繁殖程度。Hawk和Boğaç对南方根结线虫、花生根结线虫和爪哇根结线虫的所有非致病型和致病型分离株均具有抗性（每个完整根系上的卵块少于10个）。本研究是关于该野生近缘种对南方根结线虫致病型分离株抗性的首次报道。结果表明，该野生近缘种对根结线虫具有广谱抗性。
