Sentences with phrase «goat grass»

As such, goat grass genes constitute a major component of the very large wheat genome.

Bread wheat was created some 10,000 years ago by a natural cross of more simple, primitive wheats with a sub-species of goat grass.

Well, spelt emerged as a result of the hybridization of emmer and wild goat grass.

The International Maize and Wheat Improvement Center (CIMMYT) and the International Centre for Agricultural Research in the Dry Areas (ICARDA) have produced many wheat x grass crosses, recreating the original, natural cross but using other goat grass species and thus greatly expanding wheat's diversity.

The commentary was sparked by the recent publication of a reference genome from Aegilops tauschii, also called goat grass.

Dr. Davis has presented some evidence that the biggest problem with wheat may be that it has twice been hybridized, expanding its genome from 14 chromosomes in its ancestral form (einkorn wheat) to 28 chromosomes (emmer wheat) through hybridization with goat grass, later to 42 chromosomes through another hybridization with Triticum grass to create modern wheat.

To drastically alter the structure of the wheat plant — such as create a bigger ear — CIMMYT researchers spent almost 20 years using standard breeding techniques to enhance traits such as fertility, branching, and robustness in varieties ranging from Polonicum wheat to wild goat grass.

Read the Nature Plants article: The goat grass genome's role in wheat improvement.

The sequencing of goat grass DNA opens the way for wheat breeders to apply a number of advanced approaches to improve the speed and precision of wheat breeding for important traits that may be found in the goat grass segment of the wheat genome.

That's how 28 - chromosome emmer wheat, for instance, mated with another 14 - chromosome wild grass, goat grass, and yielded the ancestor of all modern wheat, the first Triticum aestivum species.
