This progress report presents the accomplishments to date for the
GrainTax Synonymy Project which was initiated on the
recommendation of participants in the Taxonomy Workshop held at the
9th International Wheat Genetics Symposium (2-7 August 1998) in
Saskatoon, Canada (See Appendix below). The project, now underway, is
developing an interactive database system that will contain
classification and synonymy tables of all modern taxonomic treatments
of the wheats dating from 1921 to present. Consistent with the
recommendations of the Taxonomy Workshop, this report is being
published concurrently in the June 1999 issue of the Annual Wheat
Newsletter and also will be posted on the GrainTax website
(http://wheat.pw.usda.gov/ggpages/GrainTax).
Classification Tables
Tables for all current and relevant historical classifications of
the wheats are now under construction on the Kansas State University
Wheat Genetics Resource Center (WGRC) web site
(http://www.ksu.edu/wgrc/Germplasm/Taxonomy). As each classification
is prepared for the WGRC site, it has been reviewed for errors in
species names and authority citations. Additionally, notations have
been made where species names are illegitimate, invalid, or ambiguous
according to the rules of the International Code of Botanical
Nomenclature (ICBN, Greuter et al. 1994). As of this writing, tables
for 24 classifications have been constructed. Eleven of these
classifications are historical; the other 13 are current treatments
followed variously by genebanks, researchers, and botanists.
Although it was the original intention of the GrainTax
Synonymy Project to limit the Classification Tables to only 12
treatments (See Appendix), this task has expanded for the following
reasons. Names from older taxonomic treatments can still be
encountered in modern literature. Historical classifications have
value either because they illustrate changing treatment concepts or
they laid the foundation for the more current treatmecnts that
followed them. All generic concepts are covered by these tables --
the traditional concept of two separate genera, Triticum L.
and Aegilops L.; the enlarged concept of one genus,
Triticum L. sensu lato; the move of the T-genome species
from Aegilops into Amblyopyrum (Jaub. & Spach) Eig;
the move of the S-genome species of Aegilops into
Triticum; and the genomi concept of many genera defined by
distinctive diploid or polyploid genomic combinations.
Classification Tables for Triticum include Percival (1921),
Flaksberger (1935), Schiemann (1948), Jakubziner (1958), Bowden
(1959), Mac Key (1966, 1988), Morris and Sears (1967), Gandilyan
(1972), Dorofeev et al. (1979), Love (1984), the Flora of
Turkey (Tan 1985), Kimber and Sears (1987), Kimber and
Feldman (1987), Mac Key (1988) and van Slageren (1994) will be
printed. Classification Tables for Aegilops include Zhukovsky
(1928), Eig (1929), Kiliara (1954), Chennaveeraiah (1960), Hammer
(1980), Witcombe (1983), Love (1984), the Flora of Turkey
(Davis 1985), and van Slageren (1994). There is also a Comparative
Classification Table which is organized by genome and contrasts the
commonly encountered Triticum and Aegilops treatments
of Dorofeev et al. (1979), Hammer (1980), Kimber and Sears (1987),
Mac Key (1988), and van Slageren (1994).
