Although the Fertile Crescent is renowned as the center of wheat domestication, archaeological studies have shown the crucial involvement of atalhyk in this process. Bread wheat (Triticum aestivum) accounts for approximately 95 percent of all wheat consumed in the world today; the other five percent consists of durum or hard wheat (T. turgidum ssp) used in pasta and semolina products. Compared to emmer wheat, modern wheat has shorter leaf longevity, and a higher net rate of photosynthesis, leaf production rate, and nitrogen content. Throughout the domestication process of wheat, the plant phenotype has undergone both rapid (within a few hundred years) and slow (thousands of years) changes, such as the weakening of the. Other methods for incorporating wild species diversity into wheat include direct crossing of Ae. China is a major producer of grains such as wheat, corn, and rice. dicoccum), which gave rise to durum or pasta wheat (Triticum turgidum ssp. The domestication of rice dates to about 4000 b.c. It was domesticated at least 12,000 years ago, created from a still-living ancestor plant known as emmer. Other characteristics considered included spike size, growing season, plant height and grain size. Other traits apparently selected for include spike size, growing season, plant height, and grain size. Wheat: Vital grain of civilization and food security.

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. The Wheat Genetics Resource Center at Kansas State University has been a leader in collecting, conserving, and exploiting wild wheat relatives for crop improvement. Mujeeb-Kazi A, Hettel GP, (editors). 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).
