Narrative |
A barley dwarfing locus Sdw1/DENSO has been mapped in the Baudin x Meatcalfe population to a genetic region on the long arm of chromosome 3H, colinear to the rice region spanning the dwarfing gene GIBBERELIC ACID-20 OXIDASE (GA20Ox). The barley orthologue, HvGA20Ox2 is a candidate for the Sdw1 locus. In the bi-parental mapping population, SNP A = associated with drarf height. SNP G = associated with normal height. |
