| Abstract: | In this study,RAPD markers were used to analyze the genetic variations of flowering Chinese cabbage accessions treated by space flight mutagenesis.Compared with the original species,genetic variations occurred in all the three accessions studied at the molecular level.Accession B had the greatest number of differential bands and the largest variation,followed in order by accession C and accession A. |
