Major Variation

Intergeneric hybrids between Triticum aestivum L. cultivars and 12 traditional Agropyron species were produced in variable frequencies, lowest being 0.35% for A. stipaefolium to a high of 41.98% for A. varnense. The crossing success of T. aestivum cultivars ranged from 'Chinese Spring' > 'Pavon-76' = 'Nacozari-75' > 'Fielder' = 'Fremont' > 'Glennson-81'. All F1 hybrids were somatically stable. The new combinations were with A. curvifolium (Thinopyrum curvifolium), A. rechingeri (T. sartorii = rechingeri), A. scythicum (T. scythicum), and A. stipaefolium (Pseudoroegeneria stipaefolia). All hybrids were perennial and possessed a modified phenotype that was intermediate between the parents involved in the hybrid combinations with major variation in spike morphology (elongated spikes with lax internodes). High-pairing hybrids, presumably owing to suppression of the Ph locus were of T. aestivum - A. scythicum (15.31 I + 2.25 II rings + 6.92 II rods + 0.32 III) and T. aestivum - A. stipaefolium (10.6 I + 7.08 II rings + 4.41 II rods + 0.54 III). In the other combinations, the pairing was either low or high, and if high, pairing was attributed to autosyndetic association of the alien genome chromosomes. Based on the meiotic pairing data, alien species that were segmental allotetraploids or partial autopolyploids, or segmental allohexaploids or autoallohexaploids, may be advantageous in developing backcross derivatives with synthetic genomes. Production of fertile amphiploids was restricted to T. aestivum - A. rechingeri. Key words: Triticum aestivum, Agropyron species, Pseudoroegeneria species, Thinopyrum species, intergeneric hybrids, crossability, wide crosses.

Elymus canadensis L. (2n = 28, SSHH), E. dahuricus Turcz. ex Griseb. (2n = 42, SSHH??), and E. cylindricus (Franch.) Honda (2n = 42, SSHH??) were successfully hybridized with Triticum aestivum L. cv. Chinese Spring (2n = 42, AABBDD) by in vivo – in vitro embryo culture. The F1 hybrids were male sterile and morphologically intermediate to their parents. The average numbers of associated chromosome arms per cell were 0.24, 2.04, and 0.65, and the mean arm association frequencies were 0.0086, 0.0486, and 0.0155, respectively. The first backcross derivatives all resulted from fusion of an euploid, hypoploid, or hyperploid unreduced F1 female gamete with a normal male gamete of common wheat. They had average numbers of associated arms per cell of 27.10, 24.36, and 23.84, and average chromosome arm association frequencies of 0.644, 0.580, and 0.568, respectively. First backcross derivatives were male sterile but morphologically, closer to their wheat parents. This study shows that no homologous genomes exist between Elymus and Triticum and that gene transfer between these two genera would be very difficult but not impossible. Key words: cytogenetics, Elymus L., Triticum L., hybrid (intergeneric).
