The putative amphidiploid and its origin diploid interspecific plants were transplanted to a glasshouse with steel structure (gutter height: 2.5 m, ridge height: 4.5 m, roof ventilation windows: 1 m, side ventilation windows: 1.2 m).
torvum, FaselisF1 and amphidiploid plants were assessed by staining fresh pollens in TTC (1% 2,3,5 triphenyl tetrazolium chloride, 60% sucrose) for 4-5h.
Production of amphidiploid plants of interspecific hybrid genotypes: There was no significant difference in amphidiploid plant production between 6 or 3 days of colchicine application.
Germination of these Co seeds established many fertile amphidiploids (tetraploid, 2n = 28, [E.sup.b][E.sup.b][E.sup.e][E.sup.e]), 13 of which were cytologically analyzed (Jauhar, 1988a, 1988b; Wang and Hsiao, 1989).
Furthermore, the amphidiploids can be crossed with tetraploid species of Thinopyrum to produce fertile hybrids (Wang, 1992), in which genetic recombinations can occur between closely related [E.sup.b] and [E.sup.e] genomes.
