| Abstract: | Summary Hybrids were produced from crossing Hordeum vulgare, H. bogdanii, Agropyron caninum and × Triticosecale onto H. parodii (6x or 4x). The rates at which hybrids were produced, expressed in terms of plantlet establishment as percent pollinated florets, ranged from 0.47%, (6x H.parodii × 6x × Triticosecale cv.  Welsh ) to 6.3% (4x H. parodii × 2x H. vulgare cv. Betzes). Based on frequencies of paired configurations at MI, autosyndetic pairing appeared to be promoted by the presence of a Secale cereale genome but suppressed by the genome of H. vulgare.Contribution No. 759 Ottawa Research Station |
