Ogihara Y et al. (1994) High-resolution cytological mapping of the long arm of chromosome 5A in common wheat using a series of deletion lines induced by gametocidal (Gc) genes of Aegilops speltoides Molecular and General Genetics 244:253-259.
Nineteen deletion lines of chromosome 5A of wheat were created using the gametocidal genes of Aegilops cylindrica. Deletion lines were characterized by microscopy of root tip cells stained with the Giemsa C-banding method, measuring distance to chromosomal banding patterns. These mutants were named 'q' followed by the number of the deletion line.
Mapping was done on Southern blots by scoring for presence / absence of hybridization of markers to deletion lines. This study mapped the Q gene to the distal end of chromosome 5A
