Development of Pink Tomato Genitors Resistant or Tolerant to Tomato Root-Knot Nematode (Meloidogyne spp.) and Tomato Spotted Wilt Virus (TSWV) Using Molecular Markers

Abstract

Tomato (Solanum lycopersicum) production faces increasing threats from biotic stress factors such as Root-knot Nematodes (Meloidogyne spp.) and Tomato Spotted Wilt Virus (TSWV), which can cause significant yield losses. In this study, molecular characterization of 154 tomato genotypes was performed to assess their resistance and tolerance to Root-knot Nematodes (Meloidogyne spp.) and Tomato Spotted Wilt Virus (TSWV) using Polymerase Chain Reaction (PCR) with SCAR markers of Mi23 and Sw5 specific to the target pathogens. PCR results successfully categorized the genotypes into resistant, heterozygous resistant/tolerant, and susceptible groups. The Mi23 marker detected genotypes carrying the mi-1.2 gene associated with resistance to Root-knot Nematodes, while the Sw5 marker identified those resistant to TSWV. The results showed that several tomato lines have both resistance and tolerance mechanisms, highlighting their potential value in breeding programs aimed at developing new cultivars with better resistance to multiple biotic stresses. While molecular data offered useful insights, field-based pathogenicity tests are needed to confirm the resistance traits under different environmental conditions. Overall, this study highlights the effectiveness of marker-assisted selection (MAS) in speeding up the identification of resistant lines and significantly advances sustainable tomato breeding strategies to minimize yield losses caused by pathogens.
