Popis:	The genetic basis of the control system responsible for suppressing the association of homoeologous chromosomes at first metaphase of meiosis in interspecific hybrids of Lolium was investigated by means of cytological and genetical analyses of a test cross between L. temulentum and L. perenne. It is concluded that more than one gene is involved. Linkage to a gene which codes for an Esterase enzyme of low electrophoretic mobility is clearly identified with the possibility that a second gene is associated with another Esterase locus. The phenotypic effect of individual pairing genes in relation to the distance between them and linked markers is discussed.
