Seven revised and 16 new descriptions of genetic stocks are included in this volume (Table 1).
Many new mutants and isozyme loci have been assigned new gene symbols and new names in various publications. However, many of them do not have descriptions published in BGN or BGS number assigned. Thus, barley workers are encouraged to prepare descriptions for new mutants and isozyme loci and submit them for assignment of BGS numbers.
