Gene symbols are proposed for 27 esterase isoenzyme alleles representing 10 loci in barley. Two new esterase loci, Est 9 and Est 10, each with an active and a silent allele, and three new alleles in previously described loci were found. A few chemical and physical characteristics of the different esterase isoenzyme systems were studied. The heat inactivation temperature differed for the isoenzymes coded by most of the loci, whereas the substrate and inhibitor specificity of the isoenzymes was less distinct. A possible relationship between some of the systems is discussed.
