Development of a SCAR Marker Linked to Tomato YellowLeaf Curl Disease Resistance Genes in Tomato
Summary: Tomato yellow leaf curl disease (TYLCD) is caused by different viral species belonging to the genus Begomovirus. Resistance to this disease has been identified in some wild tomato relatives and some of these have been used for intensive genetic studies, which have so far led to the mapping of five tomato yellow leave curl virus resistance genes (Ty-1_Ty-5). Pyramiding resistance alleles is desirable and could be simplified by the use of molecular markers tightly linked to the resistance. The purpose of this study was the development of molecular markers linked to the tomato yellow leaf curl virus (TYLCV) resistance genes. A total of 800 UBC RAPD primers were primary screened on TYLCV resistant and susceptible inbred lines. In addition, 20 TYLCV susceptible commercial hybrids were screened. Of these, two markers tightly linked to Ty-1 and Ty-3 genes. One of these was successfully converted into co-dominant SCAR marker. This SCAR marker can be used in breeding program for the selection of the Ty-1 and Ty-3 genes for TYLCV resistance.
