Crosses between rye plants from selected lines for high and low B chromosome transmission rate were carried out to determine the location of the genes controlling B transmission rate. Our results show that they are located on the Bs and we hypothesize that such ‘genes’ are sites for chiasma formation. Our results also suggest that rye B chromosome polymorphism is controlled mainly by the Bs.
