Abstract: TA1229 is a near-isogenic line in the Lycopersicon esculentum cv E6203 background and contains a 24-cM introgression at the bottom of chromosome 1 from L.hirsutum acc.LA1777. TA1229 has high yield genes. By the means of the hybridization and backcross with the elite tomato material-9706, a set of sub-NILs which have high yield trait derived from TA1229 were developed. And the fragment length of these sub-NILs was shorter than 24-cM. Through yield analysis ,16 high yield tomato materials were obtained and QTL affecting yield was located between TG53 and TG158.
