Abstract: SRAP ( Sequence-related amplified polymorphism) was analyzed between mitochondrial DNA of cytoplasm male sterility line 21A and its maintainer line 21B of pepper. The analysis showed that a total of 1 440 amplified fragments and nine polymorphic fragments between 100-1 000 bp were detected by applying 128 SRAP primer combinations; the polymorphic fragment percentage was 0. 63%; seven of the polymorphic fragments was detected in male sterility line 21A. The polymorphic fragments were isolated,cloned and sequenced,blast of the 9 clones in GenBank showed that it all have homologous with energy metabolism genes. According to the sequences, three specific primers were designed to transform the SRAP marker to more stable SCAR markers,and they only detected in the 21A line, this suggested that the newly detected fragments related to cytoplasm male sterility.
