Key to gene symbol "germplasm" information |
i: | Near-isogenic stocks, with number of backcrosses indicated. |
tv: | Tetraploid stocks. |
| s: | Homologous chromosome-substitution stocks, with number of backcrosses indicated. |
tv2: | Tetraploid stocks with two or more genes affecting the trait. |
| tr: | Translocation line of common wheat. |
idv: | Near-isogenic line of diploid wheat. |
| v: | Cultivaral hexaploid stocks in increasing order of genetic complexity. |
dv: | Diploid stocks. |
| v2: | Cultivaral hexaploid stocks with two or more genes affecting the trait. |
al: | Alien species. |
| ad: | Alien chromo some addition 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. |
| su: | Alien chromosome substitution line. |
c: | Cloning details and gene structure |
| itv: | Near-isogenic tetraploid stocks. |
