Galling index and reproduction factor of nematode isolates were assessed in a pot assay and resistance-breaking isolates were determined according to their reproduction index. Among the isolates, only two isolates of  <i>M. luci </i> (Or-2 and Pr-1) had a similar galling index on susceptible and resistant tomato (P ≤ 0.05). Four isolates of  <i>M. luci </i> (Çr-19, Or-2, Pr-1 and Pr-2), two isolates of  <i>M. arenaria </i> (A-7 and Sn-11) and an isolate of  <i>M. incognita </i> (A-11) produced more eggs than the initial inoculum on resistant tomato. These root-knot nematode isolates, except two isolates of  <i>M. arenaria </i>, were classified as resistance-breaking isolates having a reproduction index higher than 10%. These findings showed that the  <i>Mi-1.2 </i> gene confers resistance to  <i>M. luci  </i>but four isolates of  <i>M. luci </i> could overcome this resistance. This is the first report for resistance-breaking isolates of  <i>M. luci  </i>in tomato <i>. </i> </span> <span lang="en-us" style="font-size:9pt;font-family:Arial, sans-serif;" xml:lang="en-us"> </span> </p> <p> </p> <p> </p>}, number={4}, publisher={Türkiye Entomoloji Derneği}, organization={Türkiye Bilimsel ve Teknolojik Araştırma Kurumu}
