The idea behind this study is to show that using high yield genes from a wild tomato can enrich tomato breeding resources and accelerate tomato breeding programs. In this study, the near-isogenic line TA1229 containing a 24-cM introgression at the bottom of chromosome 1 from Lycopersicon acc. LA1777, affects several higher yield traits. The TA1229×9706 BC1 population was analyzed by marker-assisted selection and the traits of the population were evaluated. Twenty-three recombinant individuals that carried a shorter segment than TA1229 were obtained. Among them, 16 lines with the chromosome 1 recombinant segment can increase tomato yield and a QTL affecting yield was found between TG53 and TG158. Sixteen recombinant lines are useful to improve the tomato variety.
