Abstract: Despite some notable successes only a fraction of the genetic variation available in wild relatives has been utilised to produce superior wheat varieties. This is as a direct result of the lack of availability of suitable high throughput technologies to detect wheat/wild relative introgressions when they occur. Here we report on the use of a new SNP array to detect wheat/wild relative introgressions in backcross progenies derived from interspecific hexaploid wheat/Ambylopyrum muticum F1 hybrids. The array enabled the detection and characterisation of 218 genome wide wheat/Am. muticum introgressions, i.e. a significant step change in the generation and detection of introgressions compared to previous work in the field. Furthermore, the frequency of introgressions detected was sufficiently high to enable the construction of seven linkage groups of the Am. muticum genome thus enabling the syntenic relationship between the wild relative and hexaploid wheat to be determined. The importance of the genetic variation from Am. muticum introduced into wheat for the development of superior varieties is discussed. This article is protected by copyright. All rights reserved.
