摘  要：
元麦膳食纤维含量丰富,β-葡聚糖含量高,保健功效强,是重要的功能性农产品。为了全面了解不同地区元麦β-葡聚糖含量的差异性及其影响因素,本研究对全国7个不同省份元麦棱型、粒色、β-葡聚糖含量进行了整理和归纳,分析了气候、遗传育种和栽培措施等方面对元麦β-葡聚糖含量的影响。针对有关元麦β-葡聚糖合成筛选的有效基因少,气候与栽培措施对元麦β-葡聚糖的影响较大等问题,提出如下解决建议:(1)通过全基因组关联分析定位筛选相关位点与候选基因,挖掘与利用和β-葡聚糖合成相关的关键或主导基因,为元麦营养育种提供分子基础。(2)实际生产中根据当地气候条件,选择高产高β-葡聚糖含量的加工用营养元麦品种,采用适宜的栽培措施,缓解不良生长环境的影响。元麦分子育种和适宜的栽培措施有助于提高元麦生长适应能力,稳定元麦β-葡聚糖的含量,保障高品质元麦原料,推动健康农业的发展。

摘  要：
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 highquality raw materials for agricultural products.
