Abstract: The comparative study on karyotypes of Vicia cracca L. populations from 8 different regions in the north of China were made. The result showed that the chromosome numbers of the different populations are 12、14 and 24 respectively. The present paper supports the standpoint that 12-chromosome-type comes from 14-chromosome-type through Rorbertsonian translocation. There are not differences on external form between plant individuals with 12-chromosome and 14-chrosome, and they should be treated as the same taxon. The plant individuals with 14-chromosome have discriminating characters on external form and they should be divided into different subspecies or variations.

Key words: Viccia cracca, chromosome, karyotype, cytogeography
