Dietary fibre (DF) is an essential component of the diet with established health benefits. Soluble DF may also have unique benefits associated with its high viscosity. However, the daily intake in UK adults is substantially below recommended guidelines. Wheat is the most important source of DF in the UK, with bread providing 20% of the daily intake. Improving wheat DF is therefore an important target. By contrast, high fibre and high viscosity are detrimental when wheat is used as feed for poultry and as raw material for alcohol production in distilling and biofuel plants. We have identified wide variation in the amounts of total and soluble fibre in the Watkins collection of wheats which were collected across the world in the 1930s. This variation will be studied in more detail and tools developed to facilitate its exploitation to produce new wheat cultivars with improved end use properties, in collaboration with a major wheat breeder and with the Scotch Whisky Research Institute

饮食纤维（DF）是具有既定健康益处的饮食的重要组成部分。可溶性DF也可能具有与其高粘度有关的独特优势。但是，英国成年人的每日摄入量基本低于建议的准则。小麦是英国最重要的DF来源，面包提供20％的日常摄入量。因此，改善小麦DF是重要的目标。相比之下，当小麦用作家禽的饲料以及用于蒸馏和生物燃料植物中的酒精生产的原料时，高纤维和高粘度是有害的。我们已经确定了沃特金斯（Watkins）在1930年代在世界各地收集的小麦集合中的总和和可溶性纤维量的广泛差异。将对这种变化进行更详细的研究和开发的工具，以促进其剥削，以与主要的小麦育种者合作，并与苏格兰威士忌研究所合作生产具有改善最终使用特性的新小麦品种
