<p>The present invention relates to the use of an SNP in the tomato nor gene as a marker to identify tomato plants, to produce tomato plants, and to produce seeds to be regenerated in tomato plants with long-life characteristics. It also relates to a process for identifying said tomato plants, as well as a process for producing the latter which includes providing a Solanum lycopersicum plant containing alleles that are characterized by said mutation in the nor gene, crossing said plant with a culture material of S. lycopersicum, collecting the seeds resulting from said crossing, regenerating the seeds into plants, and identifying and selecting the plants that contain said long-life characteristic by employing said SNP for this purpose. Finally it also relates to a process for producing seeds that are regenerated into tomato plants having long-life characteristics.</p> |
