title: Linkage relationships of esterase loci in rye (Secale cereale L.).
abstract: Genetic analysis of esterase polymorphism in rye inbred lines with isoelectric focusing in polyacrylamide flat gels yielded evidence for the existence of at least ten esterase loci, Est 1-Est 10. The loci can be attributed to four different linkage groups (Est 1/ Est 2/Est 3/Est 5/Est 6/Est 7), (Est 4), (Est 8/Est 9), and (Est 10). Loci Est 5/Est 6/Est 7 and Est 8/Est 9, respectively, are tightly linked with a maximum recombination frequency of 0.2% and can therefore be regarded as compound loci which possibly originated in tandem duplications.
