Alien chromosome introgression transferring characters into bread wheat

In situ hybridization is now widely used to identify the nature and size of chromosome, chromosome arm and chromosome segment introgressions from alien or wild species in plant breeding lines. The molecular cytogenetics research group has several projects investigating introgression of chromosomes into wheat from rye, Thinopyrum (2x and 6x), Aegilops and other species or…
