بررسی تنوع ژنتیکی جمعیت های جوی وحشی و زراعی براساس چند شکلی پروتئین های ذخیره ای

Although, It is now generally accepted that domestication of barley is assumed to have taken place from Hordeum vulgare L. subsp. Spontaneum, however, it is not clear whether cultivated barley is of monophyletic origin or the domestication events happened in other parts of the world besides the Fertile Crescent. In this study in order to determine the center or centers of diversity and domestication of barley, 266 wild barley H. spontaneum in the Fertile Crescent region and beyond, with 44 samples of barley crops around the world were examined by Storage proteins . For Hordeins of D, C and B, were observed 12 , 21 and 20 different patterns respectively. Genetic parameters , such as number patterns and genetic diversity index showed Fertile Crescent region especially southern West of Iran, north of Iraq , South East of Turkey and Jordan were the major centers of plant diversity wild barley H. spontaneum. However, parts of North Africa and East Asia could be used as a secondary center of diversity of this plant are discussed. The study of genetic distances showed that wild barley genotypes of north of Iraq and South East of Turkey, were the nearest populations to the modern cultivated samples. This result indicates that this areas are considered the most likely for barley domestication.
