Metabolome dynamics during wheat domestication. Expert Answer. Domestication of wheat By Ahmet Meng on Wednesday, May 18, 2022 Wheat is a grain product with about 25,000 different varieties today. Another possible method is that the early farmers harvested wheat that was ripe but not yet self-pollinated, thus harvesting the wheat that was still on the plant.

"Wheat Domestication." CBOT May soybeans were 17 cents higher at $14.96 a bushel and CBOT May soft red winter wheat was up 4 cents at $7.09-1/2 a bushel. The move brought the reserve price closer to the 2023-24 minimum support price (MSP) of Rs 2,125 per quintal.

The earliest finds of domesticated einkorn and emmer wheat date back to the Abu Hureyra region in Syria, to the Epi-Paleolithic period, when the Younger Dryas began, about 13,00012,000 years ago. Part of wheats adaptability is due to the fact that it occurs both as winter habit varieties (requiring a cold period of 6 to 8 weeks to trigger reproduction), and spring habit varieties (not requiring the cold period). Much later, another hybridization occurred between domesticated emmer wheat (AABB) and Ae.
