Mutant Germplasm Repository
Joint service of the IAEA and Food and Agriculture Organization (FAO). Registry and distribution
system for plant breeders and geneticists of important crops induced to mutate using radiation or chemicals.
During the past fifty years, varieties of a large number of crops have been induced
to mutate with chemicals and radiation. Many of these mutants were either released as new varieties or were further used
as parents in conventional crossing and selection. However, the use of these mutants has been mostly local or regional.
Only in a few cases have the mutants been widely used. In many instances, the widespread use of valuable mutants
has been limited by non-availability of seeds and propagules, and by lack of information on individual mutants.
