[Submit comment/correction]

Gene	Pch (Triticum)  [ Marker Report ]
Synonym	Other name Pch1 Doussinault G et al. (1983) Transfer of a dominant gene for resistance to eyespot disease from a wild grass to hexaploid wheat. Nature 303:698-700.
Gene Class	Reaction to Pseudocercosporella herpotrichoides (Fron) Deighton
Reference	McIntosh RA et al. (1995) Catalogue of gene symbols for wheat. Proceedings of the 8th International Wheat Genetics Symposium 1333-1500. [ Show all 6 ]

Chromosome Arm	7DL Koebner RMD et al. (1988) Wheat endopeptidase: genetic control, polymorphism, intrachromosomal gene location and alien variation. Genome 30:186-192. Worland AJ et al. (1988) Location of a gene for resistance to eyespot (Pseudocercosporella herpotrichoides) on chromosome 7D of bread wheat. Plant Breeding 101:43-51.
Germplasm	Hexaploid stock 5L 219 Vahl U and Muller G (1991) Endopeptidase EP-1 as a marker for the eyespot resistance gene Pch-1 from Aegilops ventricosa in wheat line 'H-93-70'. Plant Breeding 107:77-79. [ Show all 9 ]
Comment	Pch is closely linked with Ep-V1 (693). Delibes et al. (174) concluded that Pch was not located in chromosome 7D whereas Law et al. (559) found that H-93-70 possessed a unique allele, Ep-D1b, in common with VPM1 and its derivatives. Eyespot resistance and Ep-A1b in chromosome 7A were genetically associated (508). Alien species: Ae. ventricosa (189). Hexaploid stock: Ae. ventricosa derivative (189).
