Microsatellite mapping of the gene for sham ramification in spikelets derived from a hexaploid wheat (Triticum spp.) accession 171ACS
Original language description
Plants with elongated spikelet rachilla (sham ramification) have been found in the progenies of a cross between hexaploid wheat (Triticum aestivum L., 2n = 6x = 42, BBAADD genome) line '171ACS' and durum wheat (T. durum Desf., 2n = 4x = 28, BBAA genome) 'Bereketli-95'. 171ACS was the carrier of the genes for sham ramification and extra glume. Expression of both of these traits was suppressed in hexaploid wheat. The gene for "sham ramification" (shr (171ACS) ) was mapped by genotyping F-2 populations using microsatellite markers. In the F-2 of 171ACS/Bereketli-95, the shr (171ACS) gene was located in chromosome arm 5AL. The shr (171ACS) gene and the gene for extra glume (exg) were completely linked. The shr (171ACS) /exg gene complex was bracketed by the markers Xbarc319 and Xbarc232 on the long arm of chromosome 5A. In F-2 hybrids between #145 and #629, and T. durum 'LD222', the shr (171ACS) gene was completely linked to the exg gene, and the shr (171ACS) /exg gene complex was located in the long arm of chromosome 5A. F-2 hybrids between two tetraploid ramified progenies and T. jakubzineri Udacz. et Shakhm. (2n = 4x = 28, BBAA genome) indicated that shr (171ACS) was allelic to shr1.
