摘　　要：采用137个InDel标记和1个SSR标记,对近年来选育的60个加工番茄骨干自交系的遗传变异进行分析。结果表明:60个加工番茄骨干自交系的平均遗传距离在0.097~0.183之间,成对比较的最小遗传距离为0.022,最大遗传距离为0.272。群体结构分析将60个骨干自交系分为2个或4个亚群,亚群分类与自交系的生物学性状之间没有明显的关联性。与2012年以前育成的25个加工番茄自交系比较发现,这60个骨干自交系的遗传变异范围相对较窄。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.
