Abstract: A Solanum lycopersicum plant including a QTL giving the plant improved resistance to Tomato Brown Rugose Fruit virus, compared to a plant without the QTL, and wherein the QTL is introgressed from S. pimpinellifolium and is to be found on chromosome 9, within the chromosomal region delimited by the SNP TO-0201220 (SEQ ID NO:1) and the SNP having SEQ ID NO:101 or on chromosome 11, within the chromosomal region delimited by markers having SEQ ID NO:102 and 115. The QTL may be chosen from those present in the genome of a plant of the seeds LVSTBRFVRES2 NCIMB accession number 43591. The QTL includes defined alleles of different SNPs on chromosome 9 or 11.

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.

Abstract: The invention relates to a method for producing haploid H, doubled haploid HD and/or dihaploid DH plants, the HD and DH being homozygous or essentially homozygous, this method being a method such as those which come under the technique of gynogenesis induced by irradiated pollen. This method comprises a step of irradiating the reproductive material of the male parent at a dose of between 160 and 190 gamma ray and/or a step of selecting the haploid H and/or DH plants by using one or more molecular marker(s).

Abstract: The invention provides a new Squash Leaf Curl Virus (SLCV) resistant gene slc-2 in cucurbit plants and plants comprising the slc-2 gene. The invention also provides molecular markers linked to slc-2 gene. The invention further provides methods of breeding to produce plants that are resistant to SLCV, and the resistant plants produced by such methods.
