Abstract Genetic variation in 60 main processing tomato inbred lines developed in recent years was analyzed using 137 InDel and one SSR markers．The results show that average genetic distances of these inbred lines were between 0.097 and 0.183．Minimal paired genetic distance was 0.022，while the maximal was 0.272．These 60 inbred lines could be grouped into two or four sub-populations based on structure analysis，which had no obvious association with the traits observed in this study．The range of genetic variation in 60 main inbred lines was narrower than that in 25 inbred lines developed before 2012．
