Abstract A novel population consisted of a set of 99 near isogenic lines (NILs) and backcross recombinant inbred lines (BCRILs) derived from a cross between the cultivated tomato Lycopersicon esculentum cv. E6206 and L. hirsutum accession LA1777 is presented. Most of the lines contain a single defined introgression from L. hirsutum in the L. esculentum genetic background and together, the lines provide a coverage of more than the 85\% of the L. hirsutum genome. These lines represent a new tool to uncover the genetic resources hidden in L. hirsutum as well as to study the genes responsible of its unique biology. Furthermore, the study of the allelic frequency and heterozygosity among BCRILs showed that specific genomic regions were likely subjected to unintentional selection pressures during the stock development. Genes involved in the reproductive behavior and (or) pollen viability are hypothesized to be responsible for these alterations.
