This is an extraction of new data reported in the current list of Recent Maize Publications (author, year) and in the Reports from Cooperators in this issue of the News Letter (author, 57:page). Genetic locations are given with recombination percentages when available; the source should be consulted for standard errors and other factors that affect the precision of the numbers. New alleles and new loci are also listed, as are, for the first time, a few genomic clones. Studies that contribute to the genetic structure of chloroplasts (ctDNA) and mitochondria (mtDNA) are cited without attempting to make a synthesis of the information; this is the first attempt to compile these reports. Finally, studies that contribute to definition of the inheritance of "resistance" and "tolerance" are cited, again for the first time. Comments, suggestions, corrections and ideas would be most welcome.
