Abstract
The present invention relates to Solanum lycopersicum (S. lycopersicum) plants with resistance to Tomato Yellow Leaf Curl Virus (TYLCV), powdery mildew (PM) and nematodes. According to the invention, the resistances are provided by coupling in cis on the same chromosome the OL4 gene conferring resistance to PM and nematodes and TY1 gene conferring resistance to TYLCV, without coupling the Mi-1 gene conferring resistance to nematodes in cis with said OL4 gene conferring resistance to PM and nematodes and TY1 gene conferring resistance to TYLCV. The genes can be present homozygously or heterozygously in the genome of the S. lycopersicum plants, and they confer resistance to TYLCV, PM and nematodes. The present invention also provides methods for making such plants, and to methods of detecting and/or selecting such plants.
