Tomato Leaf Curl

Solanum lycopersicum L.

A viral disease of tomato caused by a complex of Begomovirus species, primarily the Tomato yellow leaf curl virus (TYLCV), transmitted by the whitefly Bemisia tabaci.

In the reference 732 varieties crop Tomato, where this is mentioned in the description.

The disease is characterized by systemic symptoms: plants exhibit stunted growth, dwarfism, shortened internodes, and a bushy appearance. Young leaves curl upwards at the margins and become chlorotic; flowering is often interrupted by flower drop, and developing fruit remain small and deformed.

In tomato breeding, resistance genes introgressed from Solanum chilense and designated with the Ty- prefix are used to protect against TYLCV. Six major loci have been identified: Ty-1, Ty-2, Ty-3, Ty-4, ty-5, and Ty-6. Resistant hybrids often combine several genes to increase the efficacy of protection against genetically variable viral strains.
