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.
«This is great news because preharvest sprouting is a very difficult trait
for wheat breeders to handle through breeding alone,» said Bikram Gill, university distinguished professor of plant pathology and director of the Wheat Genetics Resource Center.
«A wheat line's adaptation to its local environment is probably one of the most important properties of the plant
for wheat breeders because it directly influences crop production,» Akhunov said.
