Breeding method of high-quality, high-yield and high-beta-glucan highland barley

The invention belongs to the technical field of crop breeding, and particularly relates to a breeding method of high-quality, high-yield and high-beta-glucan highland barley. The highland barley variety obtained by adopting the breeding method disclosed by the invention has the advantages that the beta-glucan content is higher and can reach more than 6%, the comprehensive character is better and more stable, the yield is higher than that of Longqing No.1 by more than 5%, the lodging resistance and disease resistance are equivalent to those of the Longqing No.1, and the waxy property is equivalent to that of Zhongwaxy No.8 (the ratio of amylopectin in total starch is more than 90%). 本发明属于作物育种技术领域，具体涉及一种优质高产和高β-葡聚糖青稞的选育方法。采用本发明所述选育方法选育得到的青稞品种β-葡聚糖含量更高，可以达到6％以上，综合性状更好更稳定，产量较陇青1号高5％以上，抗倒、抗病与陇青1号相当，糯性与中糯8号相当(支链淀粉占总淀粉比大于90％以上)。
