site on their ahort arms. The 1E chromosome has strong telomeric pSc119.2 signal on
both arms and also an Afa family site on the long arm subterminally. The 2E chromosome
show strong pSc119.2 signs terminally on the short arm and a terminal and a subterminal
band on the long arm.
The 3E chromosome has a subterminal Afa family site and strong pSc119.2 bands on both
arms in terminal position. A double pSc119.2 signal and an Afa family site was detected
on the long arm terminally of the 4E chromosome, while the short arm has a telomeric
pSc119.2 hybridization site.
Molecular cytogenetic characterization of the individual E genome chromosomes will help
us to analyze the genome composition of the progenies of wheat × Agropyron hybrids.
