Abstract:

Tomato yellow leaf curl disease (TYLCD) is the most destructive disease of tomato. It can cause serious loss, and is the main limiting factor in tomato production in many parts of the world. It is spread by silverleaf whiteflies, also known as Bemisia tabaci. The high variability among tomato yellow leaf curl virus isolates from different geographical areas makes progress in breeding for resistance to TYLCD slowly. This paper reviews detection and control of TYLCV, current advance of study on the screening of TYLCD-resistance, methods of resistance identification, genes with resistance/tolerance to TYLCD and molecular marker. The problems to be solved and prospects of TYLCD-resistant breeding were discussed.

Key words: tomato yellow leaf curl disease (TYLCD), resistance gene, molecular marker, breeding
