A Database for Triticeae and Avena
CIMMYT is pleased to announce the release of the Wheat Fingerprinting
Database, a Microsoft Access Database containing molecular-marker
characterization data from wheat germ plasm. This germ plasm includes
CIMMYT cultivars, breeding lines, and landraces. A simple user's
manual is included as an additional Microsoft WORD file.
Both files are downloadable from the CIMMYT website at http://www.cimmyt.org/english/wps/publs/Catalogdb/index.cfm.
If your internet connection does not support downloading large
files, you may obtain a free CD-ROM version from CIMMYT by contacting
Liliana Villaseñor (firstname.lastname@example.org). Microsoft
Access must already be installed on your computer in order to
open and run the database.
The database was constructed around linked tables containing
information on the studies that generated the data, the genotypes
that were fingerprinted, the markers used in fingerprinting, and
the marker data itself. Users may input or receive data in various
formats through the use of forms provided with the program, and
query functions allow subsets of data to be generated. Currently,
all data are from individuals from heterogenous populations or
pure lines, but a second table that handles population data (with
multiple alleles and allele frequencies) is available and marker
data will be available in this table in the near future. The
CIMMYT Wheat Fingerprinting Database currently holds 32,518 data
points, which are all SSR marker loci scored in five separate
studies, which analyzed between 40 and 240 individuals or pure
lines; marker data for 494 genotypes total are currently available.
Both the functionalities (form tools and queries) and the data
are expected to increase in the future, and the database on the
CIMMYT website will be updated periodically.
This data is freely available without restrictions, however,

published works and posters. Comments and questions about the
database and its contents may be referred to Marilyn Warburton

feedback about the usefulness of the data and how it is being
