In this study, Meloidogyne incognita (Kofoid & White, 1919) (Rhabditida: Meloidogynidae) and Fusarium oxysporum f. sp. The effect of radicis-lycopersic Jarvis & Shoemaker (FORL) interaction on nematod reproduction and purity severity has been studied in the varieties of hybrid tomatoes. The study, under controlled conditions, includes five combinations of individual, simultaneous and sequential inoculations of M. incognita, Adel, Alberty, Armstrong, Body, Gülizar and Kaplan F1 tomato hybrid varieties between January and May 2021. The test was completed after 60 days. Simultaneous inoculation has increased the number of M. incognita gall and egg packages in the Adel, Armstrong, Body and Gülizar tomatoes. The highest number of gall and egg packages in the varieties of Alberty and Kaplan tomatoes was detected in the FORL inoculation (N+10FORL) 10 days after M. incognita inoculation. The highest severity of the disease occurred in the application of N+10FORL in all tomato hybrids and was followed in the form of Gülizar, Kaplan, Body, Alberty, Armstrong and Adel. Meloidogyne incognita showed high fertility in Alberty and Body varieties and with the application N+10FORL the FORL resistance was broken. Meloidogyne incognita was not reproduced in the Adel and Armstrong tomato hybrids and therefore the disease was not observed. The findings showed that the development of root-coral nematodes is an important factor affecting the continuity of FORL resistance.

The interaction of Meloidogyne incognita (Kofoid & White, 1919) (Rhabditida: Meloidogynidae) and Fusarium oxysporum f. sp. radicis-lycopersici Jarvis & Shoemaker (FORL) on nematode reproduction and wilt severity was investigated in tomato hybrids in this study. The study included with five combinations of individual, simultaneous and sequential inoculations of M. incognita and FORL to tomato F1 hybrids Adel, Alberty, Armstrong, Body, Gülizar and Kaplan in January-May 2021 under controlled conditions. The experiment was completed after 60 days. Simultaneous inoculation increased M. incognita galls and egg masses in Adel, Armstrong, Body, and Gülizar. The highest gall and egg mass numbers occurred with FORL inoculation 10 days after M. incognita inoculation (N+10 FORL) in Alberty and Kaplan. The highest disease incidence occurred in all tomato hybrids at the application of N+10 FORL and was followed by Gülizar, Kaplan, Body, Alberty, Armstrong and Adel. Meloidogyne incognita showed high reproductive rates in Alberty and Body, and FORL resistance was overcome with treatment N+10 FORL. Meloidogyne incognita was unable to reproduce in Adel and Armstrong and thus no disease was seen. The results indicated that the development of root-knot nematodes is a significant factor affecting the durability of FORL resistance.
