A genome-wide association analysis of quantitative trait loci for protein fraction content in Tibetan wild barley

The genetic associations and differences of four protein fractions were investigated in Tibetan wild barley. Albumin, globulin and hordein contents were under genetic control probably via multiple genes/quantitative trait loci. A correlation analysis showed that globulin was significantly associated with albumin, glutelin and hordein, while hordein was closely correlated with glutelin.
