Plant breeders advance food security by linking genes and genomes to traits affecting crop productivity. The availability of whole genome DNA markers made it possible to map quantitative trait loci (QTL) affecting complex traits such as yield and its stability and to deploy them in breeding, in our case, better tomatoes. Now we have the tools to move beyond ‘one gene at a time’ and address a higher level of organization: the role of interacting gene communities in determining the phenotype. Mapping of epistatic genes is difficult because typically the populations are small and the two-dimensional genome scans carry a heavy statistical penalty due to the multiple comparisons. Yet, epistasis is the bread and butter of daily breeding where successful hybrids maximize the benefits from the introduced trait into the right genetic context. To zoom-in on epistatic QTL, we developed backcross-inbred lines (BILs) between the drought tolerant wild tomato species Solanum pennellii and the cultivated tomato (Solanum lycopersicum). After two backcrosses the BILs, composed of 3000 lines, were selfed and these are being phenotyped for diversity of traits. The results clearly show that it is possible to identify interacting genomic regions that lead to epistatic morphological species-specific phenotypes as well as influencing total yield in the field.
