- Synthetic wheat is
obtained as a result of a cross between a tetraploid specie,
Triticum durum, and a diploid one, Aegilops tauschi, following by an
artificial duplication of the genome by colchicine.
- Synthetic wheat is
made by intercrossing modern tetraploid durum wheat with derivatives
of goat grass to recreate the natural hybridization made thousands
of years ago that resulted in modern hexaploid bread wheat.
- Synthetic wheats also
appear to be resistant to a large number of major wheat pests and
diseases.
- Fortunately, some of
the synthetic wheats are highly resistant to this new strain, but
whether this is due to major or minor genes is not known.
- These primary
synthetic wheats are then further crossed to conventional hexaploid
lines and form derived synthetic wheats.
