III. Zealand 1981

This list is based on new data reported in the current Recent Maize Publications (author, year) and in the Reports from Cooperators (name, 55). Recombination percentages and notes show genetic locations; new alleles and new loci are listed with descriptive words. Nonstandard symbols, overlaps of symbols, or differences in interpretation are identified by * preceding the symbol. Listings of organelle-genome designations and localizations have not yet been attempted, more because of the difficulty in defining firm standards for nomenclature and for mapping than because of any lack of solid data and observations [Applicants for open seats on the Extranuclear Regulatory Commission should send their reprints and suggestions to Zealand, 210 Curtis Hall, Univ. of Missouri, Columbia, MO 65211]. I accept responsibility for any errors and misses, and call upon your enthusiastic corrections and new observations.

Help Wanted

*E5-I, E5-II nonconforming symbols

Cytoplasms standards for designations of "cma", "N", "cytopl", etc. are not keeping pace with new knowledge

Nomenclature specifications of alleles (especially for isozymes) is falling behind our ability to make discriminations among "isoalleles" differing in strain of origin, isolation number, etc.
