The present invention relates to novel tomato plants producing fruits displaying a modified sugar content, particularly displaying an increased sucrose content. The present invention also relates to seeds and parts of said plants, for example fruits. The present invention further relates to methods of making and using such seeds and plants. The present invention also relates to a novel sucrose modifier SucMod allele, which, when combined with a sucrose accumulation TIV allele derived from a green-fruited wild tomato accession, significantly alters the proportion of sugar stored in the fruit, confers increased fruit sucrose content at the expense of hexose sugars and results in a fruit with a distinctive flavour. La présente invention concerne de nouveaux plants de tomates produisant des fruits affichant une teneur en sucre modifiée, affichant particulièrement une teneur accrue en saccharose. La présente invention concerne également des graines et des parties desdits plants, par exemple des fruits. La présente invention concerne en outre des procédés de fabrication et l'utilisation de tels graines et plants. La présente invention concerne également une allèle de modification de saccharose SucMod, qui, lorsqu'il est combiné à un allèle d'accumulation de saccharose TIV provenant d'une obtention de tomate sauvage à fruit vert, altère significativement la proportion du sucre stocké dans le fruit, confère une teneur accrue en saccharose du fruit au détriment des sucres d'hexose et résulte en un fruit ayant un arôme distinctif.
