Intergeneric hybrids obtained in CIMMYT between some Triticeae were cytogenetically analyzed, and are discussed. A few possessed the maternal euploid composition, devoid of any detectable alien chromosomes. Other plants had the somatic counts expected from the cross-combinations. Hordeum vulgare x Triticum aestivum hybrids with a chiasmata frequency range of 2.47 to 2.63 per cell suggest homoeologous chromosome pairing. T. aestivum x Elymus giganteus had a mean of 1.2 rod bivalent fomation. The H. vulgare x Elymus (S2S2H2H2H3H3, 2n=6x=42) hybrid with a lesser than expected mean chiasmata frequency (4.77) suggests an evaluation of the pairing relationships amongst the HH2H3 genomes. Backcross progeines were obtained in a few hybrids assisted by post-pollination gibberellic acid (75 ppm) application.
