The frequencies and geographical distribution of B chromosomes of rye (Secale cereale L.) collected from various localities in Korea were investigated. All of the 15 strains of rye investigated were found to have B chromosomes, and the frequencies of B chromosomes ranged from 6 % to 51 % with 20.1 % average. Plants with 2Bs seem to be the most stable in populations with B chromosomes. Of 1400 plants examined, one plant was observed to have a deficient-B chromosome in Buyo rye
