10. Organization of the Catalogue
Information is given in the following order, where possible:
1. Gene symbol, with principal reference to the particular gene or gene symbol
in parenthesis.
2. Synonyms (with reference(s) in parenthesis).
3. Chromosome and chromosome-arm location, if known, with references in parenthesis.
4. Stocks carrying the particular gene in order of presentation.
i:= Near-isogenic stocks, with number of backcrosses indicated.
s: = Homologous chromosome-substitution stocks, with number of
backcrosses indicated.
v:= Cultivaral hexaploid stocks in increasing order of genetic
complexity.
v2: = Cultivaral hexaploid stocks with two or more genes affecting
the trait
d: = Alien chromosome addition line.
su: = Alien chromosome substitution line.
itv: = Near-isogenic tetraploid stocks.
tv: = Tetraploid stocks.
tv2: = Tetraploid stocks with two or more genes affecting the
trait
dv: = Diploid p?stocks.
al: = Alien species.
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.
Where more than a single gene affecting a character is listed, e.g., Gabo D3
{645) under D1, the reference refers to the literature source reporting
D1 in Gabo, and not necessarily to D3.
Abbreviations: CS= Chinese Sprint, Tc=Thatcher.
Note: Due to limitations with the database, Greek symbols were
converted to words or Roman letters (alpha or a, beta or b, etc.). For author
names with accents or special letters, the most similar Roman letter was used.
