Comment	Present with Rht9 in Akakomugi and Mara (Rao and Rao, 1980). Borner et al., (1996) found no evidence of orthologous GA-sensitive genes in rye, but reviewed evidence for orthologous GA-insensitive genes. The close linkage of Rht8 and Xgwm261-2D permitted the use of the microsatellite as a marker for the detection of allelic variants at the Rht8 locus (Worland et al., 1998). Mapping Information: Xgwm484-2D (proximal) - 19.9 cM - Rht8 - 0.6 cM - Xgwm261-2D (distal) (Korzun et al., 1998). A survey of Chinese cultivars showed 13 alleles of Xgwm261-2D (Liu et al., 2005). Allele sizes for Xgwm261 in U.S. eastern and central wheat cultivars are given in (Guedira et al., 2010).
