Abstract
The genetic control of the fastest migrating glutamate oxaloacetate transaminase zone (GOT 1) of rye (Secale cereale L.) was studied. The results indicated that GOT 1 is under the control of two nonlinked loci that have alleles in common. These two loci are probably the result of a gene duplication. One of the Got1 loci has been located in chromosome arm 7Rq of S. cereale because of its close linkage to the an(anthocyaninless) gene. The Got1 duplication is also present in Secale montanum Guss.
