Glossary of abbreviations

Prefixes used in the source Catalogue of Gene Symbols for Wheat to label germplasm stocks and reference entries.

v:

Cultivaral hexaploid stocks in increasing order of genetic complexity.

v2:

Cultivaral hexaploid stocks with two or more genes affecting the trait.

i:

Near-isogenic stocks, with number of backcrosses indicated.

s:

Homologous chromosome-substitution stocks, with number of backcrosses indicated.

tr:

Translocation line of common wheat.

tv:

Tetraploid stocks.

tv2:

Tetraploid stocks with two or more genes affecting the trait.

itv:

Near-isogenic tetraploid stocks.

dv:

Diploid stocks.

idv:

Near-isogenic line of diploid wheat.

al:

Alien species.

ad:

Alien chromosome addition line.

su:

Alien chromosome substitution line.

ma:

Reference to mapping information involving agronomic and morphological traits and molecular markers under gene entries will generally be restricted to values of less than 10 cM. Values higher than this would be of less use in genetics and plant breeding and, in any case, should be available from the genetic linkage section of the Catalogue or from genetic maps. Higher values will be used in the case of flanking markers.

c:

Cloning details and gene structure.
