Genome relationships among Elytrigia ( = Agropyron) elongata, E. stipifolia, E. elongata 4x, E. caespitosa, E. intermedia, and E. elongata 10x
Canadian Journal of Genetics and Cytology 23(3): 481-492
Hybrids were obtained via embryo culture from the crosses E. elongata (2x) X E. elongata (4x), E. stipifolia X E. elongata (4x), E. elongata (4x) X E. caespitosa and E. intermedia X E. caespitosa. E. elongata (10x) was crossed with four Triticum aestivum addition lines carrying different ditelosomes of E. elongata (2x). E. intermedia was crossed with a T. aestivum addition line carrying telosome 7el1 alpha of E. elongata (10x). The S genome of E. stipifolia appeared to be related only remotely to the E genome of E. elongata (2x). E. elongata (4x) appeared to have two modified E genomes which were designated Es and Esc.
