Abstract:: Ten 100% male sterility maintainer lines of the clustered pepper were taken as experimental materials,which were provided by Qingdao Agricultural University.The method of evaluating 10 maintainer lines was agronomic characters combined with InDel markers in this study.The object was to evaluate the male sterile lines and its applications in crossbreeding.The results showed that the maintainer line 16010-2 had the best level,and 16002 was the second.So,the male sterile lines were the excellent female parent in crossbreeding of clustered pepper.The maintainer lines 16006 and 16010-6 had significantly higher color value than other materials.So they could be used as the excellent female parent in crossbreeding for high color value.The evaluation of agronomic characters and genetic relationship showed that these maintainer lines were similar among 16012-1,16012-2,16010-2 and 16010-4.In crossbreeding,the four lines could be combined into one line to reduce the breeding workload.
