PLANT FORMATION FROM POLLEN OF TETRAPLOID WHEAT SPECIES AND TRITICUM-TAUSCHII

Anther cultures were performed with T. tauschii, T. monococcum and 13 tetraploid wheat species including T. turgidum spp. durum. Embryos wer e induced from pollen in all species except T monococcum. The tetraplo id wheat species showed an average embryo induction rate of 4.5% based on plated anthers. Mainly non-green pollen plantlets were regenerated from T tauschii, T polonicum, T dicoccoides, T carthlicum, T turanicu m, T. dicoccon, T. ispahanicum and T turgidum ssp. durum cv. ''MONDUR' '. Average regeneration of embryos to plantlets was 22.4% in tetraploi d wheat, but only 3% of the regenerated plantlets were green, all resu lting from one accession of T dicoccon.
