Abstract
Meiotic configuration of a cultivated rye with B chromosomes from China was characterized. Plants with two B chromosomes formed the highest frequency of a bivalent of B chromosomes while the multivalent formation of B chromosomes in plants with four B chromosomes was relatively high. The existence of B chromosomes had negligible effect on the mean chiasma frequency of A chromosomes. Spontaneous reciprocal translocations of A chromosomes were also detected in two out of 40 plants examined with the length of chromosome segment involved in translocations assumed to be different in the two translocation heterozygotes.
