In order in study resourses of rice cytoplasm extensively,we have isolated restrictive mtDNA from callus. A comparative analysis of the mtDNA in eliolated seedling and in callus of a year’ s. culture has been conducted. Restriction fragment patterns of mtDNA isolated from these two sources were identical. We have compared mtDNA of Nonghu. Liuqianxin, Liming male sterile cytoplasms and the results show that.BamHI patterns of mtDNA from ST type are almost identical.
