Abstract

A case of translocation between A and B chromosomes was recorded in the B-chromosome carrying material of pearl millet. This was induced through chemical treatment with EMS. The B-chromosomes never pair with A-chromosomes, but pair among themselves to form bivalents and multivalcnts. In the experimental material under study at pachytene and diakinesis stages in PMCs, A and B chromosome associations were observed.
