TRANSLOCATIONS occur spontaneously or may be induced by external agents which give rise to changes in chromosomal arrangement and heredity. Viable translocation heterozygotes can be examined cytologically in large numbers. Induced exchanges might allow rearrangement of the karyotype of species such as Dactylis glomerata eliminating or altering various types of gene action. This may lead to a greater expression of agronomically desirable characteristics and at the same time provide a mechanism for conserving valuable gene combinations in sexual reproduction.
