Development of single nucleotide polymorphism (SNP) markers for selection of Ve gene of tomato Verticillium wilt resistance

Tomato Verticillium wilt, caused by Verticillium dahliae and V. alboatrum is a soil-born fungal disease. Use of host resistance is an effective and environment-friendly method to control this disease. Marker assisted selection (MAS) has become very important and useful in selection of Verticillium wilt resistance genes in tomato (Solanuum lycopersicum L. syn Lycopersicon esculentum Mill.). The objective of this research was to identify Ve gene-derived single nucleotide polymorphism (SNP)markers for MAS in tomato breeding. Six gene-derived SNP markers specific for Ve locus were identified and validated to be useful in selecting Ve resistance gene in different tomato germplasm.
