BREEDING PROCESSING TOMATO HYBRIDS TOLERANT TO TOMATO YELLOW LEAF CURL DISEASE IN CHINESE TAIPEI
Tomato yellow leaf curl disease (TYLCD) became a major constraint of tomato production in Chinese Taipei in the mid-1990s and the major tomato-infecting begomovirus in Chinese Taipei are Tomato leaf curl Taiwan virus (ToLCTWV) and Tomato yellow leaf curl Thailand virus (TYLCTHV). Distribution of ToLCTWV and TYLCTHV varies in Chinese Taipei but can occur in the same fields and co-infect tomato plants. Therefore, evaluation of the selected gene combinations of Ty-1, Ty-2, and Ty-3 for tolerance to ToLCTWV and TYLCTHV were studied. It was demonstrated that heterozygous for Ty-1, Ty-2 and Ty-3, showed the highest tolerance to TYLCD in Chinese Taipei. Therefore, it should be possible to develop future processing tomato hybrids for Chinese Taipei that possess sufficiently high levels of TYLCD resistance.
