Abstract :Tomato (Solanum lycopersicum L.) is one of the most cultivated vegetables both in Türkiye and in the world. Türkiye is the 4th tomato producing country after China, India and the USA. According to consumer demands, tomato varieties such as pink, beef, bunch, cocktail are grown. The main goals in breeding are high yield, quality and resistance to stress factors, and molecular marker-assisted selection is a fast and reliable method, especially in determining the presence or absence of resistance genes to biotic stress factors. In this study, the resistance genes determined for 339 advanced tomato lines, which have the potential to become parent lines due to their agro morphological characteristics and disease resistance against Meloidogyne incognita (Root-knot nematode), Tomato spotted wilt virus (TSWV), Tomato mosaic virus (ToMV) and Verticillium wilt in the plant material. 235 were homozygous resistant to root-knot nematode, 172 homozygous resistant to Verticillium wilt, 201 homozygous resistant to TSWV and 211 homozygous resistant to ToMV were determined. It has been seen that breeding programs can b e created with the results obtained.
