Postharvest shelf-life is a critical trait for fleshy fruit and so studies of genotypes with long shelf-life (LSL) phenotypes are of great potential importance, since they can lead to strategies for crop improvement. Examples of such a genotype are the Delayed Fruit Deterioration (DFD) tomato, and most accessions of the Tomatiga de Ramellet (TdR) Mediterranean landrace group, some of which have a particularly dramatic LSL phenotype and remain palatable for many months after reaching a fully ripe stage. The TdR accessions collectively show a wide variation in shelf-life, although, the basis of this variation is not known. Moreover, little has been reported regarding the relationship between cultivation conditions, fruit shelf-life and specific genetic loci. Here we show that the LSL trait in those landraces is both partially associated with a defined genetic component, in the form of the alcobaca (alc) mutation, and is profoundly affected by the irrigation regime during cultivation.
