Abstract:

Naked barley, which has rich dietary fiber, high β-glucan content and strong health care effect, is an important functional agricultural product. In order to understand comprehensively the difference of naked barley β-glucan content and its influencing factors in different areas, we sorted and summarized the row type, grain color and β-glucan content of naked barley in 7 different provinces, and analyzed the influence of climate, genetic breeding and cultivation measures on naked barley β-glucan content. Answering the questions such as insufficient effective genes are related to naked barley β-glucan synthesis and the climate and cultural techniques have obvious influence on naked barley β-glucan, the following solutions are proposed: (1) to provide molecular basis for nutrition breeding of naked barley, we should locate and screen relevant sites and candidate genes by genome-wide association analysis, dig and utilize key or dominant genes which are related to naked barley β-glucan synthesis; (2) to alleviate the impact of adverse growth environment in the actual production, we should select the naked barley varieties which have high yield and high β-glucan content to process, and adopt appropriate cultivation measures according to the local climatic conditions. To promote the development of healthy agriculture, the molecular breeding and suitable cultivation practices of naked barley are conducive to improving its growth adaptability and stabilize its β-glucan content, and guarantee high-quality raw materials for agricultural products.

Key words: naked barley, β-glucan content, climate, genetic breeding, cultivation measures
